But Caspian terns aren't fully dedicated to particular nesting sites, and are amenable to moving.
|
|
Skimmers, terns, gulls, herons, snappers, striped bass, fluke, even opportunistic raccoons hunt these fish relentlessly.
|
|
Pelicans, ibises, stilts, avocets, coots, ducks, kingfishers, and terns fly around the marsh in the hundreds.

Big fish, seals, cormorants, gulls, and terns congregate in the tides, plucking out herring and mackerel as they move.
|
|
The goal: Getting more terns to breed farther south and eat herring, sardines and other fish in the protected bay.
|
|
His hobbies include swimming, sunbathing, and leaping out of the water to scoop up Arctic terns in his giant, gaping chops.
|
|
Those problems didn't exist in San Francisco Bay, the only coastal site chosen to entice terns away from East Sand Island.
|
|
In the rippling heat, hundreds of terns swept up on white wings, drifting over a barge chugging against the muddy current.
|
|
On Cape Cod, Good Housekeeping reported, forty thousand terns were killed in a single season by one agent of the hat trade.

Scientists in the Bay Area planted 400 plastic decoys and solar-powered speakers that played mating and nesting calls of migratory Caspian terns.
|
|
More than once, a flock of terns or a bobbing seal tipped me off to a fishy spot I might otherwise have overlooked.
|
|
The North Wales Wildlife Trust has been asking that fragile wildlife populations — thousands of terns nest here every summer — be taken into consideration.
|
|
To persuade some migrating Caspian terns to stop short of the Columbia River, scientists planted plastic decoys and patio speakers in San Francisco Bay.
|
|
But that doesn't stop traveling terns, which are themselves protected under the Migratory Bird Treaty Act, from eating the salmon and undermining their recovery.
|
|
After the 2017 breeding season, the scientists removed the plastic dummies and speakers, but Caspian terns kept returning to the area on their own.
|
|
Sleek black loons, herring gulls, harlequin ducks and oldsquaw dive at the fish on the surface, and eagles, falcons, terns and plovers glide above.
|
|
Before the 4723 breeding season, the teams erected rows of black fabric fences and stakes with flapping streamers to successfully shoo terns from Rice Island.
|
|
Encouraged by the terns' attraction to East Sand Island, biologists broadened the plan to seven other sites hundreds of miles away in Oregon and California.
|
|
There, he and his team placed nearly 400 dummy terns, as well as solar-powered patio speakers that played the birds' mating and nesting calls.
|
|
With colonies expanding, scientists anticipate the birds themselves would function as the plastic decoys had, luring more terns to the new grounds at Don Edwards.
|
|
Winterton Beach also supports a plethora of wildlife from grey seals, adders, natterjack toads, and the UK's largest colony of terns (a type of seabird).
|
|
In order to protect the birds, Birmingham Audubon did not report its findings to the public until after the least terns had completed their nesting cycle.
|
|
Terns, frigates and farcelas - including the Manutara, the symbolic bird in ancestral Rapa Nui rituals - now "adorn" their nests not with algae or stones, but with garbage.
|
|
"Terns in general respond very successfully to social attraction," said Stephen Kress, founder of the National Audubon Society's Seabird Restoration Program and a pioneer of the technique.
|
|
Numbers and colors on leg bands attached to the birds by biologists show that many terns in the refuge came from other spots around San Francisco Bay.
|
|
With their snowy white bodies, black crowns and sharp red bills, the decoys looked like real Caspian terns, a graceful migratory bird the size of a large crow.
|
|
The San Francisco Bay tern re-population hasn't yet made much of a dent in the numbers of terns eating salmon and trout in the Columbia River Estuary.
|
|
Footage of giant trevally fish leaping out of the water to nom on young arctic terns was the first collective chill Blue Planet II sent down the nation's spines.
|
|
In 2014, the Army Corps of Engineers modified five of those islands to make them hospitable to Caspian terns, which create small hollows in gravelly ground for their nests.
|
|
According to a survey conducted by biologists early in this year's nesting season, 380 Caspian terns were seen on the islands, and more were likely to arrive to nest.
|
|
Not too many tricky clues today, unless something is really outside one's wheelhouse, like not knowing the actor LIAM Hemsworth at 26A or the crosswordese bird TERNS at 2D.

A no-nonsense 26-year-old from a small Iowa town, she was part of a team of Army Corps biologists counting plovers as well as endangered interior least terns.
|
|
Least terns, which are protected by the federal government under the Migratory Bird Treaty Act, often lay their eggs on wide-open beachfronts, digging shallow nests beneath the sandy surface.
|
|
The scientists enticed these Rice Island terns 2472 miles closer to the Pacific Ocean, to East Sand Island, where they could dine on anchovies and herring rather than salmon and trout.
|
|
Drops in water levels reduced the numbers of fish for terns to eat, and coyotes and other animals could easily cross to the islands to prey on tern eggs and chicks.
|
|
The goal of those doppelgängers was to lure terns to breed on the islands, and, in doing so, prevent endangered salmon and trout living hundreds of miles to the north from vanishing.
|
|
It is also the locus for millions of migrating birds, arriving each spring from nearly every continent on Earth to raise the next generation of swans, terns, sandpipers, loons, eiders, and others.
|
|
A sequence of fish leaping from the Indian Ocean to snatch fledgling terns from the air is edited with ideal savagery, a thrilling lack of sentimentality: a splashy half-dozen feather-crushing strikes.
|
|
And while it's not expected that all of the birds will settle for San Francisco Bay, the effort could point the way toward limiting the terns' annual northward migration while still preserving their numbers.
|
|
We cruised by 12-foot-high islands composed of conch shells that harvesters, dating back to the indigenous Arawak, cast off after taking the meat, creating pearly pink mounds where terns posed in profile.
|
|
Along the way, you can see the full range of lower Penobscot Bay islands, from Seal Island — a former bombing range now managed for nesting puffins and terns — to Vinalhaven, marked by three wind turbines.
|
|
To lure the birds, Dr. Roby and his team set out 2380 fake Caspian terns on East Sand Island and played audio recordings of real tern colonies every spring and summer between 22019 and 2001.

A day trip to the beach might put you in gazing distance of several species of aggressive gulls, dive-bombing terns, adorable plovers, and regal ospreys, while a quick train ride upstate will reveal bald eagles.
|
|
According to a Tuesday news release from the Audubon Society, the group discovered on July 10 that visiting beachgoers constructed a makeshift volleyball court on top of the breeding ground for least terns on Sand Island.
|
|
After nearly being hunted to extinction for feathers for women's hats in the 1800s, the Midwestern population of least terns started doing better until after World War II, Fish and Wildlife Service recovery biologist Paul Hartfield said.
|
|
Scheduled for the South Battery Triangle, the celebration will offer bird talks and walks — the terns nest on the island's decommissioned piers — as well as children's activities, like making tern masks, oyster shell necklaces and feather crowns.
|
|
Under a blazing hot sun, white terns cruised overhead and dotted the trees, their fuzzy chicks cooling themselves in puddles by the side of the rough path Mr. Obama passed over as he took in the lush landscape.
|
|
The group said it has since reported the incident to the U.S. Fish and Wildlife Service because least terns are federally protected under the Migratory Bird Treaty Act and added that DOJ is leading the investigation into the matter.
|
|
Starting in 2008, the U.S. Army Corps of Engineers created new islands suitable for nesting at each site and teamed with Bird Research Northwest, a collaboration between biologists and federal agencies, to use social attraction to coax terns farther away from the Columbia River.
|
|
WASHINGTON — As the state of Virginia prepared for a major bridge and tunnel expansion in the tidewaters of the Chesapeake Bay last year, engineers understood that the nesting grounds of 25,000 gulls, black skimmers, royal terns and other seabirds were about to be plowed under.
|
|
Arctic terns from Greenland were shown by radio geolocation to average on their annual migrations. Most terns breed on open sandy or rocky areas on coasts and islands. The yellow-billed, large-billed, and black-fronted terns breed only on rivers, and common, least and little terns also sometimes use inland locations. The marsh terns, Trudeau's tern and some Forster's terns nest in inland marshes.
|
|
They often form mixed colonies with other terns, such as common and Sandwich terns.
|
|
The Aleutian terns frequently nests with Arctic Terns in Alaska and Common Terns in Siberia. It also happens that colonies of Mew Gull (Larus canus) are close to the Aleutian tern nests. Less aggressive than Arctic Terns; Onychoprion aleutica is frequently chased at colonies and often excluded from mixed- species foraging areas by Arctic Terns. The latter can also jeopardize the Aleutian tern foraging activity by stealing its food.
|
|
Four species of tern breed at Forvie, building their nests among the dunes and on the beach. Little terns and arctic terns favour the foreshore and raised beaches, while the sandwich terns and common terns nest amongst the marram tussocks of the dune system.The Story of Forvie National Nature Reserve. p. 13. The breeding success of the terns has fluctuated widely over the years,The Story of Forvie National Nature Reserve. p. 14.

|
Arctic, common, and roseate terns have been regulars, and in 2005 they were joined for the first time by nesting least terns.
|
|
Noddy terns (Anous stolidus), least terns (Sterna albifrons), sooty terns (Sterna fuscata), and royal terns (Thalasseus maximus) have all been recorded as nesting on nearby Pelican Cay, but not on Hans Lollik Island. Other bird species seen on Hans Lollik include the ubiquitous pearly-eyed thrasher (Margarops fuscatus), the bananaquit (Coeroba flaveloa), the oystercatcher (Haematopus pallitus), and the sparrowhawk (Falco sparverius).
|
|
The IBA was identified as such by BirdLife International because it supports a small breeding colony of West Indian whistling ducks as well as populations of American flamingos, white-tailed tropicbirds, laughing gulls, gull-billed terns, royal terns, least terns, Bahama woodstars and Bahama mockingbirds.
|
|
The islands have been identified by BirdLife International as an Important Bird Area (IBA) because they have supported over 1% of the world populations of lesser crested terns (with up to 1000 breeding pairs) and bridled terns (up to 10,000 breeding pairs). Some 120 pairs of roseate terns bred in the IBA in 1985, and up to 1500 non-breeding black-naped terns have been recorded there.
|
|
Brown noddy nest on stump of Casuarina equisetifolia Terns are normally monogamous, although trios or female-female pairings have been observed in at least three species. Most terns breed annually and at the same time of year, but some tropical species may nest at intervals shorter than 12 months or asynchronously. Most terns become sexually mature when aged three, although some small species may breed in their second year. Some large sea terns, including the sooty and bridled terns, are four or older when they first breed.
|
|
The IBA was identified as such by BirdLife International because it supports a small breeding colony of least terns as well as non-breeding royal terns.
|
|
In March 2011 there were 14 Terns on the Federal Aviation Administration register, including 4 Tern IIs and one Tern 17M. All Terns are registered in the US as Experimental - Amateur-built In March 2011 there were two Terns registered with Transport Canada, both amateur-builts.
|
|
The islands have been identified by BirdLife International as an Important Bird Area (IBA) because they support over 1% of the world population of roseate terns, as well as a large breeding colony of greater crested terns, with up to about 10,000 birds of each species recorded. The greater crested terns nest mainly on Sandy Island, with small numbers of silver gulls. As well as roseate terns, birds recorded as nesting on Low Rock include pied cormorants (150), and bridled (1000), black-naped (800) and lesser crested (440) terns.
|
|
Least terns nest on the refuge in several locations. In the mid-1980s, common terns nested in the salt marsh on the Lower Wells and Little River divisions. Roseate terns (Sterna dougallii) nested on West Goose Rocks Island in 1985, and lately, have been observed along Crescent Surf Beach in the Upper Wells Division. In 2003, Crescent Surf Beach hosted the largest nesting colony (157 pairs) of least terns in Maine.
|
|
The nearby Brook Islands are smaller and made up of North, Tween, Middle and South islands, the first three of which comprise the Brook Islands National Park. These islands are used mainly by nesting birds. It is important not to disturb the birds during breeding seasons. Birds found here include the Torresian imperial-pigeon (estimated at over 40,000), bridled terns, black-naped terns, roseate terns and little terns.
|
|
Seabird colonies are present in the coastal belt. The Sept Frères islands, in particular have breeding colonies of swift terns (Sterna bergii) and lesser-crested terns (Sterna bengalensis).
|
|
Aleutian terns fly very gracefully; their flight is strong and undeviating, and their wing beats are slower than those of Arctic and Common terns. They mostly fly above the ocean rather than above mainland. Similarly to other terns species, the Aleutian tern walks relatively slowly because of its short legs.
|
|
The IBA was identified as such by BirdLife International because it supports a small breeding colony of least terns as well as populations of common terns and brown pelicans.
|
|
Sterna is a genus of terns in the bird family Laridae. Sterna is derived from Old English "stearn" which appears in the poem The Seafarer; a similar word was used to refer to terns by the Frisians. It used to encompass most "white" terns indiscriminately, but mtDNA sequence comparisons have recently determined that this arrangement is paraphyletic. It is now restricted to the typical medium-sized white terns occurring near-globally in coastal regions.
|
|
The islands have been identified by BirdLife International as an Important Bird Area (IBA) because they support over 1% of the world populations of fairy and roseate terns, and of sooty oystercatchers. Greater crested terns breed there irregularly, sometimes in large numbers. Other birds breeding on the islands include ospreys, white-bellied sea eagles, pied oystercatchers, Caspian terns and bridled terns. The islands support 12–15 breeding pairs of beach stone- curlews.
|
|
Australian sea lions (referred to as "hair seals" at the time) were abundant at Dangerous Reef in 1904. Photographs from the 1907 show Australian sealions and cormorants inhabiting the reef and are supported by written accounts. Early 20th century descriptions note cormorants and terns there as "prolific", and detail gulls preying on unattended cormorant eggs, while the eggs of terns appeared untouched. Also noted were the presence of Greater crested terns, Little terns and Pacific gulls.
|
|
Young Arctic terns have a grey back and black bill, and juvenile roseate terns have a distinctive scalloped "saddle".Vinicombe et al. (1990) pp. 133–138. Hybrids between common and roseate terns have been recorded, particularly from the US, and the intermediate plumage and calls shown by these birds is a potential identification pitfall.
|
|
Most terns hunt fish by diving but some pick insects off the surface of fresh water. Terns are generally long-lived birds, with several species known to live in excess of 30 years.
|
|
His observations revealed that Foula's sheep target unfledged Arctic terns.
|
|
The island group has been identified as an Important Bird Area (IBA) by BirdLife International because it supports large numbers of breeding bridled terns as well as smaller numbers of other tern species. Estimated numbers of bridled terns nesting in the four years between 1993-1999 when surveys were made varied from 5000 to 50,000. Roseate and black-naped terns nest irregularly on the northern islets while black-naped, bridled and roseate terns have been recorded nesting on Dudley Island.
|
|
It is also home to resident willow ptarmigans and Arctic terns.
|
|
When adults take food back to the nest, they recognise their young by call, rather than visual identification. The common tern may attempt to steal fish from Arctic terns, but might itself be harassed by kleptoparasitic skuas, laughing gulls, roseate terns, or by other common terns while bringing fish back to its nest. In one study, two males whose mates had died spent much time stealing food from neighbouring broods. Terns normally drink in flight, usually taking seawater in preference to freshwater, if both are available.
|
|
Adult terns may be hunted by owls and raptors, and their chicks and eggs may be taken by herons, crows or gulls. Less obvious nest predators include ruddy turnstones in the Arctic, and gull-billed terns in little tern colonies. Adults may be robbed of their catch by avian kleptoparasites such as frigatebirds, skuas, other terns or large gulls.Harrison (1988) pp. 320–323.
|
|
This habit greatly increases their food-collecting ability during bad weather when fish swim deeper, out of reach of plunge-diving terns, but still within reach of the deeper-diving Puffins. In winter, the forehead becomes white and the bill black. Juvenile roseate terns have a scaly appearance like juvenile Sandwich Terns, but a fuller black cap than that species.
|
|
There are bird sanctuaries on many of the islands as well as turtle nesting sites on Culebra. Leatherback, green sea and hawksbill sea turtles use the beaches for nesting. The archipelagos bird sanctuaries are home to brown boobies, laughing gulls, sooty terns, bridled terns and noddy terns. An estimated 50,000 seabirds find their way back to the sanctuaries every year.
|
|
Further down the tidal zone a visitor will often see Sandwich terns and common terns, as well as a variety of gulls and smaller waders including redshanks, greenshanks, turnstones, ringed plovers, pied wagtails, and other sandpipers.
|
|
Pollution has been a problem in some areas, and in the 1960s and 1970s DDT caused egg loss through thinning of the shells. In the 1980s, organochlorides caused severe declines in the Great Lakes area of the US. Because of their sensitivity to pollutants, terns are sometimes used as indicators of contamination levels. Habitat enhancements used to increase the breeding success of terns include floating nest platforms for black, common and Caspian terns, and artificial islands created for a number of different species. More specialised interventions include providing nest boxes for roseate terns, which normally nest in the shelter of tallish vegetation, and using artificial eelgrass mats to encourage common terns to nest in areas not vulnerable to flooding.
|
|
Thalasseus, the crested terns, is a genus of eight species of terns in the family Laridae. It has a worldwide distribution, and many of its species are abundant and well-known birds in their ranges. This genus had originally been created by Friedrich Boie in 1822, but had been abandoned until a 2005 study confirmed the need for a separate genus for the crested terns. These large terns breed in very dense colonies on coasts and islands, and exceptionally inland on suitable large freshwater lakes close to the coast.
|
|
Dolly's Cay (or Dolly's Rock) is a remote rock on the Great Bahama Bank in the series of cays running southeast from Andros Island, and is around east south east of the southeast tip of Andros. It is part of South Andros District. The cay is used for nesting by bridled terns, sooty terns, Sandwich terns, and royal terns, which were last verified by James Parnell in 1998. These birds are monitored as part of the West Indies Seabird Geographic Information System,West Indies Seabird Geographic Information System .
|
|
It sometimes nests among Arctic terns, which, like most white terns, are fiercely defensive of their nest and young and will attack large predators. The Aleutian tern, however, is not aggressive in defence of its nests or young.
|
|
Early season crow predation and late season owl and coyote predation depressed productivity. The refuge controls diurnal predators such as crows and foxes with several techniques, including hazing, fencing, trapping, and shooting. Least terns also nest at Laudholm Beach, Goose Rocks, Higgins, and Reid State Park. During migration, large numbers of common terns, along with smaller numbers of roseate terns (15), stage at Crescent Surf Beach.
|

Roseate tern in flight. Lady Isle is owned by the Marquess of Ailsa and was for many years leased out as a bird sanctuary with a bird observatory and warden's post built and run by the Scottish Society for the Protection of Wild Birds (SSPWB). Common terns and Arctic terns used to nest here and roseate terns had been observed on many occasions.Booth, David & Perrott, David.
|
|
The keeper's house seems to be home to a large colony of terns.
|
|
The island hosts the San Francisco Bay’s largest nesting colony of Caspian terns. The terns are relatively recent arrivals, first recorded in the south bay in 1922 and nesting on Brooks Island since around 1980. They now occupy much of the man-made sandspit that stretches west from the north side of the island. The terns feed on fish from areas around the Golden Gate and San Pablo Bay.
|
|
These walled areas have enabled a build-up of soil and the establishment of vegetation, notably tree mallow (Lavatera arborea), which provides nesting cover for the birds. The smaller Bill has very little vegetation. Rockabill is an important seabird breeding island, especially notable for its terns. It is an internationally important site for roseate terns, with the largest colony in Europe, 1,597 pairs, and 2,085 pairs of Common Terns (2017 data).
|
|
Gaillard Island is also the only Alabama nesting site for Caspian terns, Sandwich terns, royal terns, and laughing gulls. The first recorded nesting of herring gulls occurred on Gaillard Island in 1986. The Alabama Department of Conservation and Natural Resources has closely monitored the colonial nesting shore and seabirds conducting annual surveys since 1998. During the first survey, they estimated that there were 10,000 nests on the island.
|
|
Birds known to nest here include royal terns, sandwich terns, black skimmers, and laughing gulls. In addition, the islet is used at various times as a loafing area by white pelicans, brown pelicans, and various other species of terns and gulls. Recent hurricanes and storms have eroded the island to such an extent that no nesting has occurred since 1992. Public access to the refuge is restricted due to its remoteness.
|
|
Identification of orange-billed terns within their range is straightforward. Crested and Cayenne terns (which do not overlap in range) can be identified by their bill colour. Of the truly orange-billed species, the only geographical overlaps are between royal and lesser crested, and between royal and elegant Terns, and in both cases the larger size and strong bill of royal tern should prevent misidentifications (in addition, lesser crested terns have a grey, not white, rump). Identification of vagrants has proved to be much more difficult however, with known hybridisation, and birds which do not match the classic character sets of individual species.
|
|
3 In 2012 the application was refused due to environmental concerns over wildlife (Sandwich terns).
|
|
The rock is also a nesting site for many sea birds, including terns and puffins.
|
|
Aleutian terns are skilled flyers and can take insects out of the air while flying.
|
|
The white tern, uniquely, lays its single egg on a bare tree branch. Depending on the species, one to three eggs make up the clutch. Most species feed on fish caught by diving from flight, but the marsh terns are insect-eaters, and some large terns will supplement their diet with small land vertebrates. Many terns are long-distance migrants, and the Arctic tern may see more daylight in a year than any other animal.
|
|
Tapeworms of the family Cyclophyllidea may also infect this species. The mite Reighardia sternae has been found in common terns from Italy, North America and China.Rothschild & Clay (1953) pp. 194–197. A study of 75 breeding common terns found that none carried blood parasites.
|
|
The coat of arms was granted on 22 May 1987. The arms show three silver terns on a blue background. Terns, a very watchful and energetic bird, are intended to symbolize the local inhabitants and the coast with the vast bird life in the area.
|
|
It has breeding populations of gulls, terns and waders, together with many wintering waders and wildfowl.
|
|
The lagoon attracts a wide variety of water birds including ducks, gulls, terns and other shorebirds.
|
|
Noddy terns There are an enormous number of birds on the island. white-capped noddy terns nest in abundance in the Pisonia trees whilst bridled terns, black-naped terns and silver gulls nest on the ground in more open areas nearer the beach. The carcasses of noddy tern chicks that fall out of nests or adults that become tangled in the sticky Pisonia seeds are quickly devoured by centipedes and the nutrients eventually returned to the soil. From December to May, migratory wedge-tailed shearwaters, colloquially known as 'mutton birds', nest in burrows in the interior of the island and their mournful wails can be heard at night.
|
|
Localities within the site include three Saint Helena plover breeding sites – Broad Bottom, Southern Pastures, and Man and Horse. Apart from red-billed tropicbirds, breeding seabirds include band- rumped storm petrels, Atlantic masked boobies, Atlantic sooty terns, brown and black noddies, white terns and, possibly, brown boobies.
|
|
The island has been identified by BirdLife International as an Important Bird Area (IBA) because it supports the largest colony of greater crested terns in the world, with up to 29,000 nests recorded there. Tern eggs are harvested by the island's traditional owners. Up to 800 silver gulls also nest on the island, and possibly bridled and roseate terns. Large numbers of migrant common and little terns roost there, as do smaller numbers of frigatebirds and brown boobies.
|
|
Little Terns are highly sensitive to human disturbance and a decrease in suitable habitat impacts on the population size due to a decrease in adequate roosting and breeding grounds.Chan, K. J. Dening. 2007. Use of sandbanks by terns in Queensland, Australia: a priority for conservation in a popular recreational waterway. Biodiversity and Conservation 16:447-464 Little terns are also impacted by pollution as poor water quality is known to negatively affect their food intake capacity.
|
|
It encompasses diverse habitats including bay beach, a brackish pond, a freshwater pond, kettle holes, tidal flats, salt marsh, freshwater marsh, shrub, grasslands, maritime oak forest, and red cedar. The refuge's diversity is critical to Long Island wildlife. The north/south orientation of the refuge's peninsula creates important habitat for shorebirds, raptors and songbirds as they navigate the coastline during migration. Habitats along the beach attract nesting piping plovers, roseate terns, least terns, common terns, and shorebirds.
|
|
This species breeds in colonies on lakes, marshes and coasts. It nests in a ground scrape and lays two to five eggs. This is a somewhat atypical tern, in appearance like a Sterna tern, but with feeding habits more like the Chlidonias marsh terns, black tern and white-winged tern. The Australian gull-billed tern does not normally plunge dive for fish like the other white terns, and has a broader diet than most other terns.
|
|
It is also thought that Arctic terns may, in spite of their small size, occasionally engage in kleptoparasitism by swooping at birds so as to startle them into releasing their catches. Several species are targeted—conspecifics, other terns (like the common tern), and some auk and grebe species. While nesting, Arctic terns are vulnerable to predation by cats and other animals. Besides being a competitor for nesting sites, the larger herring gull steals eggs and hatchlings.
|
|
Crested terns, Sterna bergii, have brilliant white feathers covering the body while the head is completely black.
|
|
Hybridisation in terns is not as frequent as in gulls; however, some mixed pairings have been noted.
|
|
Seagulls and terns nest on Nahlieli. The islands are part of the Rosh HaNikra Islands Nature Reserve.
|
|
Terns of several species will feed on invertebrates, following the plough or hunting on foot on mudflats. The marsh terns normally catch insects in the air or pick them off the surface of fresh water. Other species will sometimes use these techniques if the opportunity arises.Svensson et al.
|
|
In 2017 it was reported that 130 pairs of common terns and four pairs of Arctic terns are nesting at the docks. Fish inhabiting the dock include eels and flounder, and freshwater species such as roach, chub and bream have been caught, as have sea trout and salmon.

The sexes are identical in appearance, but young birds are readily distinguishable from adults. Terns have a non-breeding plumage, which usually involves a white forehead and much-reduced black cap. The terns are birds of open habitats that typically breed in noisy colonies and lay their eggs on bare ground with little or no nest material. Marsh terns construct floating nests from the vegetation in their wetland habitats, and a few species build simple nests in trees, on cliffs or in crevices.

The Aleutian tern (Onychoprion aleutica) is a migratory bird living in the subarctic region of the globe most of the year. It is frequently associated with the Arctic tern, which it closely resembles. While both species have a black cap, but the Aleutian tern may be distinguished by its white forehead (although juvenile Arctic terns also have white foreheads). During breeding season, the Arctic terns have bright red bills, feet, and legs while those of the Aleutian terns are black.
|
|
Juvenile lesser crested terns resemble same-age Sandwich terns, but with a yellow-orange bill, and paler overall, with only faint dark crescents on the mantle feathers. There are two other orange-billed terns within the range of this species, royal tern and Greater crested tern. Both are much larger and stouter-billed; royal also has a white rump and tail, while crested (which shares the grey rump) is darker overall above and has a yellower bill. See also orange-billed tern.

The major threat to the terns here is predation by rats; in 1978 rats killed 17 adult terns including 14 roseate terns, as well as taking all the eggs and young of that year. The RSPB warden the site to protect the terns; management measures they have undertaken here to help increase the roseate tern population include small-scale control of vegetation and provision of nestboxes, although it is thought that the number of breeding pairs at this site is primarily dependent on the overall health of the Irish Sea population. The site first came to national attention among birders in July 2005 when a sooty tern paid a very brief visit, before relocating to The Skerries and Cemlyn.
|
|
After 4–5 weeks, the chicks start fledging. Aleutian terns are easily disturbed from nests. As soon as an intrusion is detected, the adults fly off the nest. They are much slower at returning to nests after being disturbed than are Arctic terns, taking up to 30 min to return.

Nurse shark Nesting birds are a common sight along the rocky coast line. The two cays have been identified as an Important Bird Area by BirdLife International because of their breeding seabirds. These include red-billed tropicbirds, brown pelicans, brown boobies, laughing gulls and least terns. Brown noddies and bridled terns also occur.
|
|
Arctic terns protect their offspring extremely aggressively by very quick drop-downs from a stationary flight over their enemies. Other birds often benefit from this behavior by breeding very close to the Arctic terns. Red-winged blackbird males help defend neighbor's nests. There are many theories as to why males behave this way.

|
The islands have been identified by BirdLife International as an Important Bird Area (IBA) because they support over 1% of the world population of roseate terns, with up to 4000 breeding pairs using the site. Other seabirds recorded as breeding in the IBA include crested and lesser crested terns, and pied cormorants.

In the early 1900s, the small colonies of common and little terns were badly affected by egg-taking, disturbance and shooting, but as protection improved the common terns population rose to 2,000 pairs by mid-century, although it subsequently declined to no more than 165 pairs by 2000, perhaps due to predation. Sandwich terns were a scarce breeder until the 1970s, but there were 4,000 pairs by 1992. Blakeney is the most important site in Britain for both Sandwich and little terns, the roughly 200 pairs of the latter species amounting to eight per cent of the British population. The 2,000 pairs of black-headed gulls sharing the breeding area with the terns are believed to protect the colony as a whole from predators like red foxes. Other nesting birds include about 20 pairs of Arctic terns and a few Mediterranean gulls in the tern colony, ringed plovers and oystercatchers on the shingle and common redshanks on the salt marsh. The waders' breeding success has been compromised by human disturbance and predation by gulls, weasels and stoats, with ringed plovers particularly affected, declining to 12 pairs in 2012 compared to 100 pairs twenty years previously.

The bird order Charadriiformes contains 18 coastal seabird and wader families. Within the order, the terns form a lineage with the gulls, and, less closely, with the skimmers, skuas, and auks. Early authors such as Conrad Gessner, Francis Willughby, and William Turner did not clearly separate terns from gulls, but Linnaeus recognised the distinction in his 1758 Systema Naturae, placing the gulls in the genus Larus and the terns in Sterna. He gave Sterna the description rostrum subulatum, "awl-shaped bill", referring to the long, pointed bills typical of this group of birds, a feature that distinguishes them from the thicker-billed gulls.Linnaeus (1758) p. 84.Jobling (2010) p. 338.Brookes (2006) p. 1510. Behaviour and morphology suggest that the terns are more closely related to the gulls than to the skimmers or skuas, and although Charles Lucien Bonaparte created the family Sternidae for the terns in 1838, for many years they were considered to be a subfamily, Sterninae, of the gull family, Laridae.

The wetland has been identified as an Important Bird Area by BirdLife International because it provides nesting, resting, and feeding habitat for over 40 bird species, including a breeding colony of least terns and wintering common terns. Snowy and piping plovers have been recorded, as have the green-throated carib and the Lesser Antillean bullfinch.
|
|
Also important to the islands are the dozen breeding pairs of Caspian terns and, in 1983 and 1986, several pairs of Australian pelicans. Little penguins and fairy terns have bred there in the past. The common tern also roosts in exceptionally large numbers and as many as 260 have been seen there at once.
|
|
Relationships between various tern species, and between the terns and the other Charadriiformes, were formerly difficult to resolve because of a poor fossil record and the misidentification of some finds.Gochfeld & Burger (1996) pp. 624–645. Following genetic research in the early twenty-first century, the terns were historically treated as a separate family: Sternidae. Most terns were formerly treated as belonging to one large genus, Sterna, with just a few dark species placed in other genera; in 1959, only the noddies and the Inca tern were excluded from Sterna.

|
An adult common tern bringing a sand eel to a juvenile Most terns hunt fish by diving, often hovering first, and the particular approach technique used can help to distinguish similar species at a distance.Hume & Pearson (1993) pp. 54–55. Sea terns often hunt in association with porpoises or predatory fish, such as bluefish, tuna or bonitos, since these large marine animals drive the prey to the surface. Sooty terns feed at night as the fish rise to the surface, and are believed to sleep on the wing since they become waterlogged easily.

A phylogenetic framework for the terns (Sternini) inferred from mtDNA sequences: implications for taxonomy and plumage evolution . Molecular Phylogenetics and Evolution 35: 459–469.. Indeed, in his 1758 Systema Naturae, Linnaeus placed the terns in the genus Sterna. However, a phylogenetic analysis found that the species in the Onychoprion clade, which includes O. aleutica, O. fuscata (Sooty tern), and O. anaethetus (Bridled tern), are related only distantly to the "typical" terns retained in a much- restricted Sterna. Still, in broader terms the genera Onychoprion and Sterna are sisters.

Birds that have to see through an air/water interface, such as terns and gulls, have more strongly coloured carotenoid pigments in the cone oil drops than other avian species.Varela, F J; Palacios, A G; Goldsmith T M (1993) "Vision, Brain, and Behavior in Birds" in Zeigler & Bischof (1993) pp. 77–94. The improved eyesight helps terns to locate shoals of fish, although it is uncertain whether they are sighting the phytoplankton on which the fish feed, or observing other terns diving for food.Lythgoe (1979) pp. 180–183.

They demonstrated overall success, with Forster's Terns preferring to use them to avoid the vulnerabilities that come with a natural nest.

Its topography consists of earth banks, rocky banks, rocky islands, sandbars, low vegetated islands, rocky islets, and sandy beaches. Notable avifauna include Laos's last known nesting little terns, river lapwings, river terns, small pratincoles and wire-tailed swallows. The Phou Xiang Thong IBA is also in the Phou Xiengthong NBCA. This IBA spans two provinces, Champasak and Salavan.

The interior of the keys are frequented by warblers and the hawks that prey on them. Coastal zones are habitat for ruddy turnstones and least sandpipers. Gulls and terns include royal terns, laughing gulls and ring- billed gulls, with brown pelicans just offshore. Wilson's plovers nest on Boca Chita Key, where nesting zones are closed during breeding season.
|
|
When the chicks are a month old they fledge or start to fly. Royal terns mature around the age of 4 years, after which they build their own nests and reproduce. Like all white terns, it is fiercely defensive of its nest and young. The royal tern and the Cayenne tern nest and breed together in Argentina and Brazil.
|
|
This fish feeds on zooplankton, including copepods, mysids, and crab larvae. It is in turn an important prey item for a variety of larger fish, including weakfish (Cynoscion regalis), striped bass (Morone saxatilis), chain pickerel (Esox niger), and bluefish (Pomatomus saltatrix). Birds such as royal terns (Thalasseus maximus) and Sandwich terns (T. sandvicensis) feed on it.
|
|
Terns often feed in flocks, especially if food is plentiful, and the fishing success rate in a flock is typically about one-third higher than for individuals. Terns have red oil droplets in the cone cells of the retinas of their eyes. This improves contrast and sharpens distance vision, especially in hazy conditions.Sinclair (1985) pp. 93–95.

Shags (694 individuals), fulmar (11,626 pairs), puffins (2,072 pairs), storm petrel, common terns, Arctic terns, bonxies and various species of gull also nest in the sea-cliffs.NTS Seabird colonies. Retrieved 27.12.2006 Manx shearwaters nested on Lianamul stack until the late 18th century, when they were driven away by puffins, and tysties have also been recorded there.

Disagreement stems from the damming of the Te Arai Stream, interfering with the life cycle of fish said to be key to the diet of fairy-terns. In 2019, scientists who have been studying fairy terns at Mangawhai on Northland's east coast now suspect the bird's decline may be linked to the removal of mangroves from the harbour.
|
|
The diet of a family of lemmings consists mostly of Saliceae. Poaceae are also in their diet. They are a well studied example of a cyclic predator−prey relationship. Terns in the Arctic target lemmings that move in groups; after attacks, lemmings seek shelter in holes or elsewhere out of the terns' territory to avoid additional attacks.

Prawn fishing is particularly productive in providing extra food, since prawns usually represent only 10–20% of the catch, the remaining being bycatch, mainly fish such as cardinalfish and gobies. Bycatch from prawn fishing can provide extra food A study of an area of the Great Barrier Reef where the number of breeding great crested terns has grown ten-fold, probably due to extra food from trawl by-catch, suggested that lesser crested and sooty terns have moved away and now breed on a part of the reef where fishing is banned. It is possible that the large increase in the number of greater crested terns may have affected other species through competition for food and nesting sites. Terns have red oil droplets in the cone cells of the retinas of their eyes.

Bird species include black oropendola, brown pelicans, frigate birds, terns, oystercatchers, willet, whimbrel, and spotted sandpiper, kingfishers, white ibis, heron, and laughing gulls.
|
|
The call of the roseate tern is a very characteristic chuwit, similar to that of the spotted redshank, quite distinct from other terns.
|
|
Predation on inland breeding terns by coyotes, bobcats, feral dogs and cats, great blue herons, Mississippi kites, and owls has also been documented.
|
|
This species breeds in very dense colonies on coasts and islands, and exceptionally inland on suitable large freshwater lakes close to the coast. It nests in a ground scrape and lays one to three eggs. Unlike some of the smaller white terns, it is not very aggressive toward potential predators, relying on the sheer density of the nests—often only apart and nesting close to other more aggressive species such as Arctic terns and black-headed gulls to avoid predation. Like all Thalasseus terns, the Sandwich tern feeds by plunge-diving for fish, almost invariably from the sea.

Large nesting colonies of brown noddies (Anous stolidous), bridled terns (Sterna anaethetus), the lesser noddy (Anous tenuirostris), red-footed booby (Sula sula) and lesser frigate birds (Fregata ariel), exist on Diego Garcia. Other nesting native birds include red-tailed tropicbirds (Phaethon rubricauda), wedge-tailed shearwaters (Puffinus pacificus), Audubon's shearwater (Puffinus iherminierii), black-naped terns (Sterna sumatrana), white (or fairy) terns (Gygis alba), striated herons (Butorides striatus), and white-breasted waterhens (Amaurornis phoenicurus).Natural Resources Management Plan (2005), paragraph 4.2.2.1.1. The 680-hectare Barton Point Nature Reserve was identified as an Important Bird Area for its large breeding colony of red- footed boobies.

West Island Conservation Park is a protected area occupying both West Island and Seal Island in coastal waters near Victor Harbor in South Australia. The park was proclaimed in 1972 following the enactment of the National Parks and Wildlife Act 1972 with the protection initially applying to West Island only which itself previously had reserve status under the Fauna Conservation Act 1964-1965. Seal Island was added to the park in 1979. The purpose of the park is to protect the breeding populations of bird species present on both islands such as little penguins, silver gulls, crested terns, Caspian terns and fairy terns.
|
|
Migratory waders recorded in the islands include some regular visitors as well as vagrants. None breeds there. However, North Keeling is important for breeding seabirds, with sizeable numbers of red-footed boobies, great and lesser frigatebirds, common noddies and white terns. Other breeding seabirds include wedge-tailed shearwaters, masked boobies, brown boobies, red-tailed and white-tailed tropicbirds, and sooty terns.

Order: CharadriiformesFamily: Laridae Laridae is a family of medium to large seabirds, the gulls, terns, and skimmers. Gulls are typically grey or white, often with black markings on the head or wings. They have stout, longish bills and webbed feet. Terns are a group of generally medium to large seabirds typically with grey or white plumage, often with black markings on the head.
|
|
Although their legs are short, terns can run well. They rarely swim, despite having webbed feet, usually landing on water only to bathe. The majority of sea terns have light grey or white body plumage as adults, with a black cap to the head. The legs and bill are various combinations of red, orange, yellow, or black depending on species.
|
|
The most common inhabitants are wedge-tailed shearwaters, sooty terns and common and black noddies. Their numbers are usually quite high and bird cries continue day and night on the island. Several species of booby migrate through the Island including masked, brown and red-footed boobies, and also the lesser frigatebird. Crested terns are also seen to migrate, although not as often.

Common terns were once plentiful in the region before industrialism drove out all but a small number of them. The banks of the Detroit River near the Trenton Channel Power Plant are one of the only places in the region where common terns regularly nest and breed. Other birds, such as bald eagles, peregrine falcons, and great blue herons also use the grounds for habitat.
|
|
Since that time unauthorised landings have been forbidden. The Island is a nesting site for black-headed gulls and the little tern. In 2008 the island had 4,886 nesting pairs of black-headed gulls and 11 nesting pairs of little terns. None of the little terns managed to raise any young that year something thought to be in part due to the number of black-headed gulls.
|
|
Notable avifauna is the last known nesting little terns (Sternula albifrons); there are also small pratincoles (Glareola lactea), river lapwings (Vanellus duvaucelii), wire-tailed swallows (Hirundo smithii), and river terns (Sterna aurantia). The Phou Xiang Thong IBA (36,650 hectare) is situated within the Phou Xiengthong NBCA (120,000 hectare). The IBA encompasses two provinces, Salavan and Champasak. The IBA is located at an altitude of above sea level.
|
|
Wildlife may be disturbed, a frequent difficulty for species that breed in exposed areas such as ringed plovers and little terns, and also for wintering geese. During the breeding season, the main breeding areas for terns and seals are fenced off and signposted. Plants can be trampled, which is a particular problem in sensitive habitats such as sand dunes and vegetated shingle.Liley (2008) pp. 10–14.

It supports internationally important numbers of breeding Sandwich and little terns, and nationally significant populations of common and Arctic terns, as well as wintering waders and wildfowl. It has a number of uncommon plants adapted to its harsh environments. It was bought by the National Trust in 1923, and became a national nature reserve. It was subsumed into the North Norfolk Coast SSSI in 1986.

DTE Energy regularly spreads crushed limestone along the banks of the Detroit River on Slocum's Island, because such an item provides a popular nesting habitat for native common terns. Common terns were once plentiful in the region before industrialism drove out all but a small number of them. Other birds, such as the bald eagles, peregrine falcons, and great blue herons also use the grounds for habitat.

On islands at the western end of the lagoon, there is an important tern colony, with the only breeding Sandwich terns in Wales. The numbers of breeding Sandwich terns have increased to around 1,500 pairs in recent years, making Cemlyn the third-largest colony in the United Kingdom. Arctic and common terns breed here regularly in smaller numbers but roseate tern now only occasionally. For this reason Cemlyn has been designated as part of the Ynys Feurig, Cemlyn Bay and The Skerries Special Protection Area along with two other nearby sites, Ynys Feurig and The Skerries, and all three are also classed by BirdLife International as an Important Bird Area.

Common tern in flight Common tern in flight Terns are seabirds in the family Laridae that have a worldwide distribution and are normally found near the sea, rivers, or wetlands. Terns are treated as a subgroup of the family Laridae which includes gulls and skimmers and consist of eleven genera. They are slender, lightly built birds with long, forked tails, narrow wings, long bills, and relatively short legs. Most species are pale grey above and white below, with a contrasting black cap to the head, but the marsh terns, the Inca tern, and some noddies have dark plumage for at least part of the year.
|
|
It avoids areas which are frequently exposed to excessive rain or wind, and also icy waters, so it does not breed as far north as the Arctic tern. The common tern breeds close to freshwater or the sea on almost any open flat habitat, including sand or shingle beaches, firm dune areas, salt marsh, or, most commonly, islands. Flat grassland or heath, or even large flat rocks may be suitable in an island environment. In mixed colonies, common terns will tolerate somewhat longer ground vegetation than Arctic terns, but avoid the even taller growth acceptable to roseate terns; the relevant factor here is the different leg lengths of the three species.
|
|
Especially in the early part of the breeding season, for no known reason, most or all of the terns will fly in silence low and fast out to sea. This phenomenon is called a "dread". This autumn juvenile in Massachusetts has a white forehead, having lost the ginger colouration characteristic of younger birds On their return to the breeding sites, the terns may loiter for a few days before settling into a territory, and the actual start of nesting may be linked to a high availability of fish. Terns defend only a small area, with distances between nests sometimes being as little as , although is more typical.

Nine small cays, with a combined area of , comprise the Swain Reefs Important Bird Area (IBA), identified as such by BirdLife International because together they support over 1% of the world population of breeding roseate terns, and even larger numbers of non- breeding roseate terns, with up to 25,000 individuals recorded there. Other birds recorded on the cays include masked and brown boobies, silver gulls, black-naped, sooty, bridled, greater crested, lesser crested and little terns, black and common noddies, and lesser frigatebirds. Cays supporting seabirds include Gannet Cay (), Bylund Cay (), Thomas Cay (), Bacchi Cay (), Frigate Cay (), Price Cay (), Distant Cay (), Riptide Cay () and Bell Cay ().

The island has been identified as an Important Bird Area (IBA) by BirdLife International because it is one of only three known locations in Seychelles which are nesting sites of Roseate terns (about 150 pairs). Also spotted are Sooty terns (about 5000 pairs) and Brown noddys (about 1000 pairs). All three species breed in dense colonies during the south-east monsoon season. green and hawksbill sea turtles also nest there.

Hays lives in Manhattan in the other portion of the year. During her stays on the island, she lives in former barracks and is assisted by other volunteer conservationists in her work. The researchers weigh the terns and help to monitor hatchlings and improve nesting conditions for them. As of 2014, over 26,000 terns lived on the island, more than 10 times the number when Hays started her work.

Body mass ranges from . In winter, the cap is lost, and there is a dark patch through the eye like a Forster's tern or a Mediterranean gull. Juvenile gull-billed terns have a fainter mask, but otherwise look much like winter adults. Juvenile Sandwich terns have a short bill, and are frequently mistaken for gull-billed tern where the latter species is uncommon, such as North Sea coasts.

Little cormorants are seen on perches around the lake. Compact flocks of brahminy ducks, as well as shovellers, pintails, gadwall, teals, pochards, geese and coots, are also seen. Nesting colonies of gull-billed terns and river terns are seen on the Nalabana Island. In 2002, the Bombay Natural History Society survey recorded 540 nests of the Indian river tern at the island, the largest nesting colony in the southeast Asia.

Parents and chicks can locate one another by call,Burton (1985) p. 123. and siblings also recognise each other's vocalisations from about the twelfth day after hatching, which helps to keep the brood together. Vocal differences reinforce species separation between closely related birds such as the least and little terns, and can help humans distinguish similar species, such as common and Arctic terns, since flight calls are unique to each species.Constantine (2006) pp. 73–77.

Aleutian terns primarily feed on small fish, but their diet also includes crustaceans, insects and zooplankton. They forage mostly by flying, hovering low over water and swooping down or surface-dipping into the water to take their food from the surface. Only contact- and surface-dipping have been observed, even in places where other species have been seen plunge-diving. Indeed, terns are considered as poor swimmers because of their small webs and short legs.

According to one study, "Crested and Caspian Terns that nest in the open are closed out by the canopy, and Little Penguins (Eudyptula minor) and Bridled Terns (Sterna anaethetus) are excluded by the lack of undergrowth". In New Zealand it has established on several seabird-dominated islands where it is considered to be a serious ecological weed and for which there are active eradication programmes, such as on North Brother Island in Cook Strait.

The Bountiful Islands are a group of small islands in the Gulf of Carpentaria, northern Australia, belonging to the state of Queensland. They have an area of 442 ha. They form an Important Bird Area because they support more than 1% of the global population of two bird species, with up to 2,000 pairs of roseate terns and 26–30,000 pairs of crested terns. It is around 450 hectares or 4.5 square km in size.

The islands have been identified by BirdLife International as an Important Bird Area (IBA) because they support over 1% of the world populations of greater crested (with up to 50,000) and roseate terns (up to 17,500). Bridled and black-naped terns also breed on the islands, which are used for nesting by large numbers of sea turtles as well.BirdLife International. (2011). Important Bird Areas factsheet: Pearce, Urquhart and Hervey Islands (Sir Edward Pellew Group).

A policy of eliminating predatory gulls preceded the recolonization of the island by a large mixed band of Arctic terns and common terns. During the Cold War, the island was used as a gunnery range and bombing test site for the United States Navy. Unexploded ordnance remains on the island, though some of it was detonated by a fire in the late 1970s. The ordnance presents no real danger to refuge staff or interns.

This improves contrast and sharpens distance vision, especially in hazy conditions. Birds that have to see through an air/water interface, such as terns and gulls, have more strongly coloured carotenoid pigments in the cone oil drops than other avian species.Varela, F. J.; Palacios, A. G.; Goldsmith T. M. (1993) "Vision, Brain, and Behavior in Birds" in Harris, Philip; Bischof, Hans-Joachim Vision, Brain, and Behavior in Birds: a comparative review Cambridge, Massachusetts: MIT Press 77–94 The improved eyesight helps terns to locate shoals of fish, although it is uncertain whether they are sighting the phytoplankton on which the fish feed, or observing other terns diving for food. Tern's eyes are not particularly ultraviolet sensitive, an adaptation more suited to terrestrial feeders like the gulls.

Woodland is limited in the SSSI, although a belt of Corsican pine planted at Holkham has provided shelter to allow other trees and shrubs to become established. The SSSI is designated as a Special Protection Area for birds because its variety of coastal habitats give it year-round importance for a number of species.

However, the tern population has been decreasing, apparently due to reduced nesting area. The sandspit is being reduced by erosion from the bay waters, and also by the encroachment of invasive plants such as ice plant and marguerite daisies. The terns face strong competition at Brooks Island from a growing population of California gulls. The gulls "compete with the terns for nesting sites, steal fish from them, take their eggs, even chicks if they're small enough".

The rats probably arrived on large fishing boats that were wrecked on the island in 1999 and 2000. Bird species include white terns, masked boobies, sooty terns, brown boobies, brown noddies, black noddies, great frigatebirds, coots, martins (swallows), cuckoos and yellow warblers. Ducks have been reported in the lagoon. The island has been identified as an Important Bird Area by BirdLife International because of the large breeding colony of masked boobies, with 110,000 individual birds recorded.

The courtship display of the Aleutian tern has never been thoroughly described, but all terns are thought to display the same strategies of courtship: ceremonial “fish flight,” “low flight,” “high flight,” and ground “parade”. The Aleutian Tern pre-courtship flights have been described in literature. Beginning on May, several terns participate in a synchronous ascending spiral flight, before the beginning of courtship in early June. Pairs do not always copulate at the colony; indeed, Mickelson et al.

Terns may be killed or injured by collisions with trawl warps, trapped in trawls or discarded gear, or hooked by longline fishing, but, unlike albatrosses and petrels, there is little evidence that overall numbers are significantly affected. An unusual incident was the incapacitation of 103 terns off Robben Island, South Africa by marine foam, generated by a combination of wave action, kelp mucilage and phytoplankton. After treatment, 90% of the birds were fit to be released.

Internationally important numbers of Sandwich and little terns breed on the island, together with common and Arctic terns The marshes also support wintering wildfowl and waders, including shelduck, wigeon, teal and curlew. brent geese feed on sea lettuce and eelgrass, preferring the former when both are available. The average number of pink-footed geese in the five winters to 2009/10 was 22,764, far exceeding the international importance level of 2,700 birds.Holt et al (2011) p. 31–32.

New Zealand fairy terns were also reportedly found in Canterbury, in the South Island. However, from the mid-1970s, the population declined rapidly. By 1984, New Zealand fairy tern breeding was restricted to three sites in Northland: the Papakanui sandspit in Kaipara Harbour, the Waipu sandspit, and the Mangawhai sandspit. Currently, New Zealand fairy terns still occupy these breeding sites, with the addition of a new breeding site in 2012 at the Te Arai Stream mouth, south of Mangawhai.

The reserve was created in 1978 to protect sea turtle and seabird colonies. There were more than 10,000 Caspian terns (Sterna caspia) in the reserve during the 1980s, and there are also many royal terns (Thalasseus maximus) and great white pelicans (Pelecanus onocrotalus). Several sea turtle species are quite populous, including loggerheads (Caretta caretta) and green turtles (Chelonia mydas). The common dolphin (Delphinus delphis) and the African manatee (Trichechus senegalensis) are also observed in the area.

Much of the terns habitat and nesting areas have been taken over by the over-abundant cormorant over the last several decades. The terns are now not commonly seen. Coastal migrants (also called "transients") include shorebirds such as plovers, turnstones, sandpipers, willet and yellowlegs. Summer residents include the seaside sparrow, sharp-tailed sparrow, Nelson's sparrow, clapper rail, mallard and black duck, herons and egrets, including the black-crowned night heron and snowy egret as well as the least tern and piping plover.

The Rachel Carson National Wildlife Refuge was established to preserve ten important estuaries that are key points along migration routes of waterfowl and other migratory birds. During harsh winters, the refuge's marshes provide vital food and cover for waterfowl and other migrating birds at a time when inland waters are frozen. The refuge also supports piping plover, least terns, peregrine falcons, bald eagles, and other state and federally protected species. Nesting success of plover and terns has benefitted from the increased habitat protection.

The nest is a shallow depression usually built on low vegetation such as mosses, lichens, field horsetail, cottongrass, hairgrass or coastal bluegrass. Both parents incubate the eggs and feed the chicks, although the female does more incubating and less fishing than her partner. Aleutian terns are reported to spend less time brooding chicks than do Arctic terns; consequently, Aleutian tern mortality rate is higher during the chick stage. The eggs typically have an elongate ovate shape and range from 40–46mm length.

Without an advanced degree, Hays began her career in 1956 in low-level positions cataloguing specimens and performing secretarial work. In 1969 Hays made her first trip to Great Gull Island, which the American Museum of Natural History had recently purchased. At that time hunting had greatly reduced the numbers of breeding pairs of common terns and roseate terns in North America. In 1969 Hays began spending six months of the year on the island working to restore the local population.

A nesting Arctic tern with an egg in Schleswig-Holstein, Germany Arctic tern nesting in southern Iceland Arctic terns flock on Patagonia Breeding begins around the third or fourth year. Arctic terns mate for life and, in most cases, return to the same colony each year. Courtship is elaborate, especially in birds nesting for the first time. Courtship begins with a so-called "high flight", where a female will chase the male to a high altitude and then slowly descend.

In 1998, an estimated 3.7% of the world's population of this bird at the time were counted nesting on the rocky outcrops. The same site is significant within North America for the numbers of colonial waterbirds using the area, especially Common terns. Other globally significant nesting areas are found at Gull Island and Sandhill Island, Little George Island and Louis Island. Birds nesting at these sites include Common and Caspian terns, Herring gull, Ring-billed gull, Double-crested cormorant and Greater scaup.

A population of Arctic terns, known locally as tirricks (stress on last syllable; an onomatopoeic word), migrates to Shetland from Antarctica during the summer. As swallows are sometimes seen as harbingers of summer elsewhere, in Yell and Shetland, it is the tirricks or terns that fulfil this role - "On Yell [the Arctic tern] has the impact of August on a heather moor, and nothing draws the islander closer to nature’s year than the first tern." Other birds that regularly visit Yell include great and Arctic skuas, various terns, eider, Eurasian whimbrel, red- throated diver, dunlin, golden plover, twite, lapwing and merlin. The Eigg, and Ern Stack in the north west of Yell, is the last known nesting site of Shetland sea eagles, which were recorded there in 1910.

It feeds by picking fish from the surface in marine environments, often in large flocks, and rarely comes to land except to breed, and can stay out to sea for 3 to 10 years. Due to the lack oil in its feathers, it cannot float, and spends that entire time on the wing. This bird is migratory and dispersive, wintering more widely through the tropical oceans. It has very marine habits compared to most terns; sooty terns are generally found inland only after severe storms.

In the 1990s, the Oregon Department of Fish and Wildlife attempted to restore the island, but wind and wave action quickly eroded it away again. In 2008, the United States Army Corps of Engineers built a nesting site at the location of the original island. It was specifically designed to resist erosion and the surface was covered with sand and gravel to create nesting habitat for Caspian terns. Since its completion, the new island has become a successful nested site for terns and other water birds.

In most species, the subsequent moult does not start until after migration, the plumage then becoming more like the adult, but with some retained juvenile feathers and a white forehead with only a partial dark cap. By the second summer, the appearance is very like the adult, and full mature plumage is usually attained by the third year. After breeding, terns moult into a winter plumage, typically showing a white forehead. Heavily worn or aberrant plumages such as melanism and albinism are much rarer in terns than in gulls.

The gull- billed tern is an opportunist predator, taking a wide variety of prey from marine, freshwater and terrestrial habitats. Depending on what is available it will eat small crabs, fish, crayfish, grasshoppers and other large insects, lizards and amphibians. Warm-blooded prey includes mice and the eggs and chicks of other beach-breeding birds; least terns, little terns and members of its own species may be victims. The greater crested tern will also occasionally catch unusual vertebrate species such as agamid lizards and green sea turtle hatchlings, and follows trawlers for discards.

It used to be grouped in the genus Sterna but is now placed on its own in the genus Gelochelidon. The gull-billed tern does not normally plunge dive for fish like the other white terns, and has a broader diet than most other terns. It largely feeds on insects taken in flight, and also often hunts over wet fields and even in brushy areas, to take amphibians and small mammals. It is also an opportunistic feeder, and has been observed to pick up and feed on dead dragonflies from the road.

Like all frigatebirds they will not alight on the water surface and are usually incapable of taking off should they accidentally do so. Great frigatebirds will also hunt seabird chicks at their breeding colonies, taking mostly the chicks of sooty terns, spectacled terns, brown noddies and black noddies. Studies show that only females (adults and juveniles) hunt in this fashion, and only a few individuals account for most of the kills. Great frigatebirds will attempt kleptoparasitism, chasing other nesting seabirds (boobies and tropicbirds in particular) in order to make them regurgitate their food.

Nesting Sandwich and common terns preen when they have been alarmed by a potential predator or when they have had an aggressive encounter with a neighboring bird, for instance. Fighting European starlings will break off their battles to preen.
|
|
External parasites include chewing lice of the genus Saemundssonia, feather lice and fleas such as Ceratophyllus borealis.Rothschild & Clay (1953) p. 82, 130. Lice are often host specific, and the closely related common and Arctic terns carry quite different species.
|
|
There are many kinds of seabirds on the coast. Pelicans and cormorants join up with terns and oystercatchers to forage for fish and shellfish on the coast. There are sea lions on the coast of Wales and other countries.
|
|
Aleutian terns are highly social. Usually, their nests are settled within loose mixed-species colonies. Monospecific colonies or isolated pairs are rare. Colony size usually ranges from 4–150 pairs, but up to 700 pairs on Sakhalin Island (Siberia).
|
|
No European tern winters so far north. This species breeds in colonies in marshes. It nests in a ground scrape and lays two or more eggs. Like all white terns, it is fiercely defensive of its nest and young.
|
|
It is uninhabited by human beings. There is no fresh water source on Haycock Island. It is sometimes nicknamed the Scout's Hat because it looks like an oversized scout hat. Haycock Island is a nesting haven for Bridled Terns.

Shorebirds and wading birds are abundant at Assateague. Breeding birds include piping plovers, great egrets and red-winged blackbirds. Seabirds include brown pelicans and several species of gulls and terns. Wooded habitats shelter ruby- crowned kinglets and white-eyed vireos.
|
|
Attempts were made in the late 1800s to capture animals from Dangerous Reef for zoological displays. Captured animals included seal pups and terns. The seals were well known residents of the reef, and were described as "plentiful" there in the 1930s.
|
|
Black noddies and white terns nest in the middle and lower branches. The root system is used by reef herons and red- tailed tropic birds. Other birds can be found in the Pisonia forest, the only one left in Samoa.
|
|
The abundance of invertebrates such as gnat larvae (chironomids) and back swimmers (Trichocorixa) are fed upon extensively by the huge shorebird and waterfowl populations that utilize the lake. Fish in these bays are fed upon by diving terns and pelicans.
|
|
Body mass ranges from . In winter, the cap is lost, and there is a dark patch through the eye like a Forster's tern or a Mediterranean gull. Juvenile Australian terns have a fainter mask, but otherwise look much like winter adults.
|
|
While the ducks generally brooding at the Little Lake in the south, the gulls and common terns prefer the islets in colonies. Lake Düden, Lake Little and their surrounding area of wetlands and steppes are declared protected area in 1992.
|
|
High Island's Great Sand Bay, on the western side of the island, is one of the last suitable Great Lakes nesting sites for the endangered piping plover. Many terns breed on a sandspit on the northeast corner of the island.
|
|
The fauna is extensive in the jungle, in the lowlands of the Coast there is an equatorial fauna such as: the American jaguar or tiger, the sloths or "light parakeets", anteaters, macaws, parrots, toucans, redfish, boobies, terns, lizards, poisonous snakes.
|
|
Breeding seabirds include little penguins, silver gulls, and crested, Caspian and fairy terns. Reptiles recorded from the island include Cunningham's spiny-tailed, White's and Peron's earless skinks. In 1977, it was reported that Australian sea lions occasionally visited the island.
|

The island is an important breeding site for sooty terns Middle Brother, also known as Île du Milieu, is an 8-hectare coral island on the Great Chagos Bank atoll of the Chagos Archipelago in the British Indian Ocean Territory. It is one of the three islands in the Three Brothers group on the western side of the atoll, and forms part of the Chagos Archipelago strict nature reserve. It has been identified as an Important Bird Area by BirdLife International for its significance as a breeding site for seabirds, notably sooty terns, of which 12,500 pair were recorded in a 2004 survey.
|
|
The archipelago has been identified by BirdLife International as an Important Bird Area (IBA) known as the Sir Joseph Banks Group Important Bird Area because it supports over 1% of the world populations of white-faced storm petrels (with up to about 180,000 breeding pairs), Cape Barren geese (up to about 1200 individuals), black-faced cormorants (from 3000 to 5000 breeding pairs), and, probably, of Pacific gulls. Other seabirds which breed in the archipelago include little penguins, silver gulls and greater crested terns. Fairy terns, eastern reef egrets, rock parrots and muttonbirds have also been recorded.
|
|
The set of sites has been identified by BirdLife International as an IBA because it supports over 1% of the world populations of Pacific gulls (Paddys Island), little penguins (with up to 15,000 breeding pairs on St Helens Island), pied oystercatchers (Georges Bay) and significant numbers of fairy terns and hooded plovers (Maurouard Beach and Peron Dunes). Other seabirds breeding on the islands include 10,000 pairs of white-faced storm- petrels, 2350 pairs of short-tailed shearwaters and 10 pairs of common diving- petrels on St Helens Island, as well as small numbers of Caspian terns and kelp gulls on Paddys Island.

Roseate tern profile As with other Sterna terns, roseate tern feeds by plunge-diving for fish, almost invariably from the sea; it is much more marine than allied terns, only rarely visiting freshwater lagoons on the coast to bathe and not fishing in fresh water. It usually dives directly, and not from the "stepped-hover" favoured by Arctic tern. The offering of fish by the male to the female is part of the courtship display. Unusual for a tern, the roseate tern shows some kleptoparasitic behaviour, stealing fish from other seabirds, at British colonies most often from puffins.
|
|
It nests in a ground scrape, often in a hollow or under dense vegetation, and lays one or two (rarely three) eggs. It is less defensive of its nest and young than other white terns, often relying on Arctic and common terns in the surrounding colony to defend them. In smaller colonies, they may rarely mate with these other tern species. The white- bellied sea-eagle (Haliaeetus leucogaster) and silver gull are known to prey on eggs and chicks, while the turnstone (Arenaria interpres), black rat (Rattus rattus) and King's skink (Egernia kingii) are suspected predators.

Passage Key has suffered substantial shoaling in recent years and is currently reduced to a small sandbar approximately long at high tide. It began in 1921 with a hurricane that destroyed a freshwater lake and most of the vegetation. The island, first known as Isla de San Francisco y Leon, then Burnaby Island, and later as Cayo del Pasaje or Passage Key, was a barrier island teaming with laughing gulls, royal terns, black skimmers, sandwich terns, brown pelicans and oystercatchers. The hurricanes of 2005 reduced the island to the current state that must be saved or allowed to disappear.

|
The terns nest on the airfield because they do not have to compete with beachgoers, and the airport fence keeps dogs and other animals out, while the airplane activity helps keep predatory hawks away from the nests. Approximately 135 nests were established there in 2007.
|
|
The reef has been identified as an Important Bird Area (IBA) by BirdLife International because its cays, with a collective land area of about a hectare, have supported over 1% of the world population of lesser crested terns (with up to 5000 nests recorded).
|
|
It was formed from sandstone, is almost treeless (one coconut tree in 1995), and covered by grass and low-growing vegetation (shrubland). It is significant as a nesting site for terns, the colonies of which are subject to frequent exploitation and disturbance by poachers.
|

Klein Bonaire has been identified by BirdLife International as an Important Bird Area (IBA) because it supports populations of threatened or restricted-range bird species, including bare-eyed pigeons, least terns and Caribbean elaenias. It is also a breeding site for Wilson's and snowy plovers.
|
|
The bay, with its wetlands and beaches, has been identified as an 83 km2 Important Bird Area (IBA) by BirdLife International because it regularly supports over 1% of the world populations of pied and sooty oystercatchers as well as small numbers of fairy terns.
|
|
Fishes, penguins, Cape cormorants, crested terns and fur seals and jellies eat this fish. This goby hides from predators within jelly tentacles when it rises to feed and reoxygenate its blood. Although targeted by purse seines, it may also be caught incidentally in trawls.
|
|
This population boom has resulted in large resident flocks of gulls that will opportunistically prey on other species, particularly the eggs and nestlings of other birds. Seriously threatened birds that share the same South Bay habitat include the snowy plover and California least tern, while less-threatened birds including black-necked stilts, American avocets, Forster's terns, and Caspian terns are also preyed upon by the abnormally large flocks of California gulls. Efforts are underway to reduce habitat for this species and find other ways to disperse the large numbers of gulls. Contrary to its name, the California Gull is the state bird of Utah.
|
|
The Tanji Bird Reserve has had around 300 species of birds recorded within it, including 82 species of Palearctic migrants. The reserve has been declared as an Important Bird Area by Birdlife International. Species seen regularly on the reserve's lagoons include Black-headed heron, white-fronted plover, Caspian tern, spur-winged plover, sanderling, Western reef heron, royal tern and lesser black-backed gull. While the Bijol Islands are an important feeding and roosting area for substantial numbers of shorebirds, seabirds, ospreys, and other birds, including Gambia's only breeding seabirds, including colonies of grey-headed gulls, slender-billed gulls, royal terns, Caspian terns, long-tailed cormorants and Western reef herons.
|
|
A recent analysis of DNA sequences supported the splitting of Sterna into several smaller genera. One study of part of the cytochrome b gene sequence found a close relationship between terns and a group of waders in the suborder Thinocori. These results are in disagreement with other molecular and morphological studies, and have been interpreted as showing either a large degree of molecular convergent evolution between the terns and these waders, or the retention of an ancient genotype. The word "stearn" was used for these birds in Old English as early as the eighth century, and appears in the poem The Seafarer, written in the ninth century or earlier.
|
|
The eyes of terns cannot accommodate under water, so they rely on accurate sighting from the air before they plunge-dive. Like other seabirds that feed at the surface or dive for food, terns have red oil droplets in the cones of their retinas; birds that have to look through an air/water interface have more deeply coloured carotenoid pigments in the oil drops than other species.Varela, F J; Palacios, A G; Goldsmith T M "Color vision in birds" in Ziegler & Bischof (1993) pp. 77–94. The pigment also improves visual contrast and sharpens distance vision, especially in hazy conditions,Sinclair (1985) pp. 88–100.

The group of sites has been identified as an IBA by BirdLife International because it supports significant numbers of critically endangered orange-bellied parrots and vulnerable fairy terns, and over 1% of the world populations of blue-billed ducks, chestnut teals, Australian white and straw-necked ibises, red-necked stints and silver gulls. The IBA regularly supports over 20,000 waterbirds, including 4000 to 15,000 waders and over 10,000 nesting seabirds. The largest Victorian colonies of white-faced storm petrels comprise some 12,400 nesting burrows on Mud Islands and South Channel Island. Mud Islands also has important breeding colonies of Australian pelicans, silver gulls, greater crested and Caspian terns, and ibises.

Levenhall Links are one of the most popular sites for birdwatching in the vicinity of Edinburgh. The ash lagoons have provided a roost site for gulls, shorebirds and terns; while the seawall provides excellent views of the flocks of sea ducks such as common eider, velvet scoter, red-breasted merganser, long-tailed duck and common goldeneye. Many rare visitors have been seen over the years including white-winged scoter, surf scoter, Wilson's phalarope, western sandpiper, marsh sandpiper, Franklin's gull and citrine wagtail. It has hosted three terns which had their first occurrences for Scotland here; namely Forster's tern, lesser crested tern and royal tern.
|
|
Unlike other species of terns which forage in the open ocean, the New Zealand fairy tern is not a plunge diver, but instead feeds in the top 5–8 cm of the water; it can capture prey in extremely shallow water such as estuaries and tidal pools. Adult birds have been observed feeding gobies (Favonigobius lentiginosus and F. exquisitus) and flounders (Rhombosolea sp.) to their chicks, and adult diet may include a substantial number of shrimps. Birds were observed foraging in Te Arai Stream, the mouth of which is a popular flocking for post-breeding fairy terns, but appeared to be getting most of their food from elsewhere.

Among those auks and terns, tried to feed these pipefish to their young as their more normal diet of sand-eels, had declined. However, the pipefish have limited nutritional value compared to the oily-fleshed sand-eels and many chicks choked on their hard, rather indigestible bodies.
|
|
The island is a breeding ground for a few seabirds, particularly southern fulmars, but also Wilson's storm petrels and Antarctic terns. Penguins, including Adélie and chinstrap penguins, visit the island infrequently. There are numerous seals, particularly crabeater seals, leopard seals and smaller numbers of southern elephant seals.

Terns have coloured oil droplets in the cones of the eye to improve distance vision Seabirds such as terns and gulls that feed at the surface or plunge for food have red oil droplets in the cones of their retinas. This improves contrast and sharpens distance vision, especially in hazy conditions. Birds that have to look through an air/water interface have more deeply coloured carotenoid pigments in the oil droplets than other species.Varela, F. J.; Palacios, A. G.; Goldsmith T. M. "Color vision of birds" in Ziegler & Bischof (1993) 77–94 This helps them to locate shoals of fish, although it is uncertain whether they are sighting the phytoplankton on which the fish feed, or other feeding birds.

The reason for their dark plumage is unknown, but it has been suggested that in tropical areas, where food resources are scarce, the less conspicuous colouration makes it harder for other noddies to detect a feeding bird. Plumage type, especially the head pattern, is linked to the phylogeny of the terns, and the pale- capped, dark-bodied noddies are believed to have diverged earlier than the other genera from an ancestral white-headed gull, followed by the partially black-headed Onychoprion and Sternula groupings. Juvenile terns typically have brown- or yellow-tinged upperparts, and the feathers have dark edges that give the plumage a scaly appearance. They have dark bands on the wings and short tails.

Masked boobies are the largest seabirds breeding on Lord Howe and can be seen nesting and gliding along the sea cliffs at Mutton Bird Point all year round. Sooty terns can be seen on the main island at Ned's and Middle Beaches, North Bay, and Blinkey Beach; the most numerous of the island's breeding seabirds, their eggs were formerly harvested for food. Common and black noddies build nests in trees and bushes, while white terns lay their single eggs precariously in a slight depression on a tree branch, and grey ternlets lay their eggs in cliff hollows. Three endemic passerine subspecies are the Lord Howe golden whistler, Lord Howe silvereye, and Lord Howe currawong.

In the early 1900s, Desecheo NWR was still a major nesting ground for thousands of seabirds. Approximately 15,000 Brown Boobies, 2,000 Red-footed Boobies (Sula sula), 2,000 Brown Noddies (Anous stolidus), 1,500 Bridled Terns (Onychoprion anaethetus), and hundreds of Magnificent Frigatebirds (Fregata magnificens), Laughing Gulls (Larus atricilla), and Sooty Terns (Onychoprion fuscatus) nested here. Invasive mammals, including goats and rats, began to impact Desecheo NWR early in the 20th century. Around and during the time of World War II, the island was used as an artillery range by the US Air Force. That and the invasive species’ damage to Desecheo's ecosystem have been severe, and by the turn of the millennium, virtually no seabirds were using the refuge.

The foraging style of the kittiwakes is often compared to the terns' foraging strategy due to their frequent hovering and their head diving quickly at the surface of the water. Instances of kittiwakes following whales are also common since they benefit from the fish fragments expelled by these huge marine mammals. Fishers and commercial fishing boats are also the frequent witnesses of big groups of kittiwakes, often mixed with other gull species and terns, hovering around their ship in order to benefit from the scraps rejected in their sewage water or thrown overboard. There are few studies focussing on their water needs, though they seem to prefer salt water to fresh water.

The lake, with its associated seasonal claypans and the nearby Barrolka Lakes to the north-east, has been identified by BirdLife International as a Important Bird Area (IBA) because it has supported over 1% of the world populations of plumed whistling-ducks, sharp-tailed sandpipers and Australian pelicans, as well as providing habitat for Australian bustards. A large colony of Australian pelicans breeds on an island at the north-eastern end of the lake. The Barrolka Lakes hold several cormorant colonies. Other birds recorded in substantial numbers include hardheads, white-headed stilts, glossy ibises, grey teals, black-tailed nativehens, Australian pratincoles, whiskered terns and Pacific black ducks, with smaller numbers of freckled ducks and white- winged black terns.
|
|
It was proposed that the Scottish Wildlife Trust might take over the isle as a reserve, however the decline of the tern colony led to this proposal being rejected. The hypothesis that the gulls were responsible for the loss of the terns is unfounded. It is more likely, though not certain, that the reduction in breeding terns across the whole of the Clyde area is due to a combination of reduced feeding grounds and limited habitats suitable for breeding due to human development. Members visited the island on 19 May 1993 to assess its value as a reserve, taking the boat from Troon harbour which regularly visits the island to maintain the lighthouse.

Despite occupying a relatively small area, 265 bird species have been observed in the protected area Poda. 46 bird species nest in the area and it is the only location on the Black Sea Coast with a mixed heron breeding colony of spoonbill, glossy ibis, purple heron, grey heron, night heron, great white egret and little egret. Other species breeding in the area are marsh harriers, common terns and little terns, and great cormorants - which have forsaken their usual breeding sites in reed beds and made their nests in the abandoned electrical pylons in the area. Its rich biodiversity is attributed to the three different types of water habitats it contains - brackish, fresh, and hyper-saline salt water.

Kingbirds attack other birds that come too close. In North America, northern mockingbirds, blue jays, and Arctic terns can peck hard enough to draw blood. In Australia, a bird attacking a person near its nest is said to swoop the person. The Australian magpie is particularly well known for this behavior.

The east coast of Mousa towards the Peerie Bard Mousa is known for grey and common seals, black guillemots, Arctic terns and storm- petrels. Mousa holds c. 6,800 breeding pairs of European storm-petrels in total. This represents about 8% of the British population and 2.6% of the world population.
|
|
Moreover, wintering area in Southeast Asia could be related to breeding population declines because this region undergoes several ecological stresses from unregulated fishing, coastal development, and pollution. Aleutian terns are very sensitive to disturbance at colonies and may seasonally or even permanently abandon their colonies in response to human disturbance.

Like all Thalasseus terns, lesser crested tern feeds by plunge-diving for fish, usually from saline environments. It usually dives directly, and not from the "stepped-hover" favoured by Arctic tern. The offering of fish by the male to the female is part of the courtship display. Great Barrier Reef, Australia.
|
|
Common terns usually breed once a year. Second clutches are possible if the first is lost. Rarely, a second clutch may be laid and incubated while some chicks from the first clutch are still being fed. The first breeding attempt is usually at four years of age, sometimes at three years.

Because of its location at the boundary between the Gulf of Maine and the Bay of Fundy, Machias Seal Island is fog-bound for many days of the year. It is also a sanctuary for seabirds such as Atlantic puffins, razorbills, common murres, common and Arctic terns, Leach's storm-petrels, and common eiders.
|
|
The site has been identified by BirdLife International as an IBA because it has supported significant numbers of freckled and pink-eared ducks, grey teals, hardheads, Australian pelicans, banded stilts, red-necked avocets and Caspian terns. It also supports populations of Eyrean grasswrens, black honeyeaters, banded whitefaces, chirruping wedgebills and cinnamon quail-thrushes.
|
|
Over a hundred species of native birds have been recorded in the sanctuary, including about 60 species of migratory birds which visit seasonally; these include terns, gulls, herons, sandpipers and cormorants. Notable species are whimbrels and brahminy kites. The sanctuary is well known for a wide variety of fish, mussels and crabs.

Penguin pool The 800 square metre enclosure for Humboldt penguins, Inca terns, cinnamon ducks and red-shouldered ducks, which was opened in 2014, is located in the direct vicinity of the Rainforest House and houses a penguin colony of ten breeding pairs. The terrain for the penguins is divided into two thirds land area and one third water area. The natural habitat of the penguins was the model for the design of the new enclosure, especially the artificial rock face: the coastal regions of northern Chile and Peru on the cold Humboldt Current. The entire enclosure was covered with a net construction, so that in addition to Humboldt penguins, Inca terns, cinnamon and red-shouldered ducks can also be kept.

A few of the 130,000 Atlantic sooty terns at Mars Bay breeding grounds, Ascension Island After cats were introduced to Ascension Island in 1815, large seabird breeding colonies were quickly wiped out everywhere except in small cat-inaccessible areas, such as on the offshore Boatswain Bird Island. Following a two-year campaign, feral cats were eradicated by 2009 and seabirds began to recolonise the main island. Ascension Island, including fourteen inshore stacks and marine habitat extending out for from the coastline, has been identified as an Important Bird Area (IBA) by BirdLife International as a breeding site for seabirds. Birds for which the IBA is significant include red-billed tropicbirds, Ascension frigatebirds (an endemic breeder), sooty terns and black noddies.

Gull populations have increased over the last century because of reduced persecution and the availability of food from human activities, and terns have been forced out of many traditional nesting areas by the larger birds. A few species are defying the trend and showing local increases, including the Arctic tern in Scandinavia, Forster's tern around the Great Lakes, the Sandwich tern in eastern North America and its yellow-billed subspecies, the Cayenne tern, in the Caribbean. Terns are protected by international legislation such as the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) and the US-Canada Migratory Bird Treaty Act of 1918. Parties to the AWEA agreement are required to engage in a wide range of conservation strategies described in a detailed action plan.

A few pairs of white-tailed tropicbirds are also nesting here. Little Tobago is also a good site from which to see birds which breed on neighbouring small islands, including red-footed booby and magnificent frigatebird. The latter species is frequently seen harassing the tropicbirds, boobies and terns. A few species of reptiles have been recorded on Little Tobago.

Samoa flying fox Amalau Valley has been described as the best place in American Samoa to observe the Many-colored Fruit Dove. There are also large numbers of White-tailed Tropicbirds, White Terns, and Brown Noddies present. Amalau Valley is a particularly great site to observe fruit bats, especially the Samoa flying fox.Watling, Dick and Dieter R. Rinke (2001).

Pelagic birds, also called oceanic birds or seabirds, live on open seas and oceans rather than inland or around more restricted waters such as rivers and lakes. Pelagic birds feed on planktonic crustaceans, squid and forage fish. Examples are the Atlantic puffin, macaroni penguins, sooty terns, shearwaters, and Procellariiformes such as the albatross, Procellariidae and petrels.

A colony of Sandwich terns on Norderoog Arctic tern on Norderoog Norderoog is a resting and hatching place for a number of rare species of marine birds. Notably the Sandwich tern (Sterna sandvicensis) has a colony. During spring and early summer, up to 5,000 couples will breed there annually. In 2007, 2,800 breeding couples were counted.
|
|
The island is known for its rich fish life. The red-footed booby and sooty tern used to breed there but are now extinct. The brown noddy and white-tailed tropicbird still breed while hundreds of lesser noddies and bridled terns roost at night. Barn owls were introduced in 1949 but died out in 1951-1952.

The Sabine's gull breeds in colonies on coasts and tundra, laying two or three spotted olive-brown eggs in a ground nest lined with grass. It is very pelagic outside the breeding season. It takes a wide variety of mainly animal food, and will eat any suitable small prey. It also steals eggs from nesting colonies of Arctic terns.
|
|
Mammals most commonly found in the park are white-tailed deer, groundhogs, minks, foxes, squirrels, and eastern chipmunks. Monson Lake State Park is located on a major corridor of the Mississippi Flyway and attracts a variety of birds. Regionally threatened or uncommon species include Henslow's sparrows, American white pelicans, Forster's terns, Franklin's gulls, horned grebes, and trumpeter swans.
|
|
Grótta and the region close by is a popular outdoor recreational area. Grótta became a nature reserve in 1974 and it is forbidden to visit it during nesting season, from 1 May to 15 July. There are about 450 couples of arctic terns in Grótta. A lighthouse was originally built in 1897, a new one was built in 1947.

Roosting with little terns, note size difference The greater crested tern occurs in tropical and warm temperate coastal parts of the Old World from South Africa around the Indian Ocean to the Pacific and Australia. The subspecies T. b. bergii and T. b. enigma breed in Southern Africa from Namibia to Tanzania, and possibly on islands around Madagascar.
|
|
Large populations of birds inhabit the island, including American oystercatcher, great blue heron, and snowy egret. There are over 320 species that are known to inhabit the island during some portion of the year. These include gulls, terns, and other shorebirds along with raptors, waterbirds, and waterfowl. The piping plover is a threatened species that nests on Assateague.

Gerrids, or water striders, are preyed upon largely by birds and some fish. Petrels, terns, and some marine fish prey on Halobates. Fish do not appear to be the main predators of water striders, but will eat them in cases of starvation. Scent gland secretions from the thorax are responsible for repelling fish from eating them.

A colony of feral rabbits was introduced in the nineteenth century, but was eliminated in 2008. Rawaki has its own species of seabird tick, Ixodes amersoni. It also boasts various species of flies, moths, leafhoppers, green bugs, and spiders. Sea birds consist of sooty, grey, and white terns; frigates, petrels and shearwaters; boobies, migratory plover and curlew.
|
|
It is also home to the following rare or protected species: sea lamprey, river lamprey, brook lamprey, white-clawed crayfish, Atlantic salmon and otter. The Lough Gill water system gets a very early run of spring salmon. A small colony of common terns breed on the lake's islands (20 pairs in 1993). Kingfishers are also found on the lake.

The average life span is 32 years.FWS Juvenile sooty terns are scaly grey above and below. The sooty tern is unlikely to be confused with any tern apart from the similarly dark-backed but smaller bridled tern (O. anaethetus). It is darker-backed than that species, and has a broader white forehead and no pale neck collar.

The south polar skua eats mainly fish, often obtained by robbing gulls, terns and even gannets of their catches. It also eats other birds, rabbits, and carrion. Like most other skua species, it continues this piratical behaviour throughout the year, showing less agility and more brute force than the smaller skuas (jaegers) when it harasses its victims.
|
|
It usually occurs in crevices in rocky areas, 5–90 metres (16–295 feet) deep. It is a very territorial fish, also being venomous to humans. They eat mollusks, crustaceans, and small fish. The young are fed upon by lingcod, cabezon, birds, rockfish, salmon, porpoises and terns, while adults are preyed upon by sharks, dolphins and seals.
|
|
The island is uninhabited in winter, but seasonal wardens are present throughout the summer to protect the nesting birds. Landing on Coquet Island for the general public is prohibited, but local boating companies from Amble sail close up to the island in good weather throughout the summer, allowing visitors to get good views of the puffins and roseate terns.
|
|
The area close to the estuary offers overwintering habitats for a number of important birds including pale- bellied Brent geese, lapwings, black-tailed godwits, and golden plovers. The mudflats are home to a variety of waders, swans and ducks. Other birds that inhabit the reserve include linnets, little terns, meadow pipits, reed buntings, skylarks, stonechats, wheatears, and wrens.
|
|
The island has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a wide range of seabirds including a breeding colony of over 600 pairs of southern giant petrels. Other birds nesting at the site include Adélie and chinstrap penguins, Antarctic terns and kelp gulls. Weddell and southern elephant seals regularly haul out.
|
|
Currently, this species is of relatively low conservation concern and does not require significant additional protection or major management, monitoring, or research action. The IUCN Red List status of the emerald shiner is of least concern. Other than being caught for use in fish bait, emerald shiners are preyed upon by birds (gulls, terns, mergansers, cormorants) and fishes.
|
|
In winter, the forehead becomes white and the body plumage a much paler grey. Juvenile whiskered terns have a ginger scaly back, and otherwise look much like winter adults. The first winter plumage is intermediate between juvenile and adult winter, with patchy ginger on the back. The whiskered tern eats small fish, amphibians, insects and crustaceans.
|
|
Common bird species include the Common Myna, Rock Dove, White-Cheeked Bulbul, Eurasian Collared Dove, Laughing Dove and House Sparrow. Other notable species are falcons, terns, wagtails, hoopoes, herons, larks, gulls, eagles and sandpipers. On the offshore territory of Halul Island, at least 38 species of seabirds have been observed. Fuwayrit is an important site for birds.

Hume (1993) pp. 79–85. The common tern hosts feather lice, which are quite different from those found in Arctic terns, despite the close relationship of the two birds.Rothschild & Clay (1953 ) p. 135. It may also be infected by parasitic worms, such as the widespread Diphyllobothrium species, the duck parasite Ligula intestinalis, and Schistocephalus species carried initially by fish.
|
|
Insects are known to be eaten during El Niño events. In southern California, least terns feed in bays and lagoons, near shore, and more than from shore in the open ocean. Elsewhere, they feed in proximity to lagoons or bay mouths. Adults do not require cover, so that they commonly roost and nest on the open ground.
|
|
The area covered by the national park is also overlapped by the Coffin Bay Important Bird Area, a non-statutory classification determined by BirdLife International. This particular IBA supports over 1% of the world populations of pied and sooty oystercatchers, as well as significant numbers of fairy terns, hooded plovers, western whipbirds, rock parrots and blue-breasted fairy-wrens.
|
|
These are by far the longest migrations known in the animal kingdom. The Arctic tern flies as well as glides through the air. It nests once every one to three years (depending on its mating cycle); once it has finished nesting it takes to the sky for another long southern migration. Arctic terns are medium-sized birds.
|
|
Other nesting birds, such as alcids, often incidentally benefit from the protection provided by nesting in an area defended by Arctic terns. The nest is usually a depression in the ground, which may or may not be lined with bits of grass or similar materials. The eggs are mottled and camouflaged. Both sexes share incubation duties.
|
|
This location is the only mainland site where leatherbacks repeatedly return to lay eggs. Rose-crowned fruit doves, fairy gerygones and grey fantails are commonly found in the canopies to the west. Along the beaches pied oystercatcher, bar-tailed godwits, tattlers and crested terns are often seen. Emus and brahminy kites can also be found in the park.

Tatiana Borisovna Ardamatskaya (; 25 October 1927 – 24 October 2011) was a Soviet-Ukrainian ornithologist and conservationist. She is known for her research on waterbirds and coastal birds of the Ukrainian Black Sea region and for her efforts to improve environmental protections for them. Her studies included Mediterranean gulls, swans, eiders, ducks, geese, and terns, among others.

Adult male at Waipu River estuary The New Zealand fairy tern is currently considered a subspecies of the fairy tern (Sternula nereis). Two other subspecies exist: Sternula nereis nereis, which breeds in western and southern Australia, and S. n. exsul, which breeds in New Caledonia. Fairy terns were first described from the Bass Strait in Australia in 1843.
|
|
The island has been classified as an Important Bird Area because it has been reported as supporting over 1% of the world's breeding population of flesh-footed shearwaters (6000-8000 pairs) and great-winged petrels (10,000-15,000 pairs). Other birds that are found on the island include wedge-tailed shearwaters, little shearwaters, Caspian terns and Pacific gulls.
|
|
The bill is yellow with a black tip, the irises are brown and the legs are yellowish. The pale grey underparts differentiate it from other small terns. It has a very rapid and characteristic wingbeat. The call is a shrill "kik" and a harsh "gree", and it also utters a descending series of "kee-ee-eer" notes.

Several hundred thousand water birds winter in these lakes, including the world's largest concentrations of little gulls and whiskered terns. Other birds making their homes in the delta include grey herons, Kentish plovers, shovelers and cormorants. Also found are egrets and ibises. Lake Bardawil and Lake Burullus are protected wetlands of international importance under the Ramsar Convention.

Its taxonomic placement was unclear for many years, as its plumage and migration inland to nest suggested it belonged with the marsh terns of the genus Chlidonias yet it did not nest in marshes like the other members of that genus. Martin Moynihan described it as "the most puzzling case", ultimately placing it in Sterna as he suspected the similarity of its breeding plumage to that of C. hybrida was due to similarity in environment and observed that the nonbreeding plumage resembled that of other members of Sterna. Gochfeld and Berger (1996) followed in keeping it in Sterna, while Charles Sibley and Burt Monroe placed it in Chlidonias. A 2005 molecular study by Bridge and colleagues placed it as a basal member of the marsh terns, settling the issue.

In Australia, predation by cats and dogs, and occasional deaths by shooting or collisions with cars, wires or light-towers have been documented. Nominate subspecies roosting with Sandwich terns in South Africa Commercial fisheries can have both positive and negative effects on the greater crested tern. Juvenile survival rates are improved where trawler discards provide extra food, and huge population increases in the southeastern Gulf of Carpentaria are thought to have been due to the development of a large prawn trawl fishery. Conversely, purse-seine fishing reduces the available food supply, and sizeable fluctuations in the numbers of great crested terns breeding in the Western Cape of South Africa are significantly related to changes in the abundance of pelagic fish, which are intensively exploited by purse-seine fishing.

Sandwich tern in flight The terns are small to medium-sized seabirds, gull-like in appearance, but usually with a more delicate, lighter build and shorter, weaker legs. They have long, pointed wings, which gives them a fast buoyant flight, and often a deeply forked tail. Most species are grey above and white below, and have a black cap which is reduced or flecked with white in the winter. The Sandwich tern was originally described by ornithologist John Latham in 1787 as Sterna sandvicensis, but was recently moved to its current genus Thalasseus (Boie, 1822) following mitochondrial DNA studies which confirmed that the three types of head pattern (white crown, black cap, and black cap with a white blaze on the forehead) found amongst the terns corresponded to distinct clades.

Caspian terns (Hydroprogne caspia), North America's largest tern, return to the Bay every spring to nest, migrating from as far away as Colombia. According to scientists from the U.S. Geological Survey, Caspian tern populations in the South Bay are declining at the same time that high levels of mercury are being found in their eggs. The highest mercury levels found in animals from the Bay were in the eggs of Caspian and Forster's (Sterna forsteri) terns that nest near the Cargill salt ponds at the mouth of the Guadalupe River. A study conducted by the U.S. Fish and Wildlife Service has found that nearly three- quarters of the eggs examined from black-crowned night heron (Nycticorax nycticorax) nests in the Guadalupe watershed contained mercury exceeding thresholds known to kill the embryos of other bird species.

Another letter, dated June 21, 1990, was sent by FWS to USACE, reporting that at least eight interior least terns, an endangered species, had been found on a small island in the Arkansas River approximately south of the site of the proposed turnpike bridge. Although the bridge was not yet under construction at the time, the anticipated eighteen-month period of bridge construction had the possibility of interfering with the terns' nesting period, which runs from mid-May to mid-August. FWS was also in favor of requiring OTA to prepare a full EIS, a process that could have taken up to three years. Further delays on the Creek Turnpike project appeared inevitable in October 1990, as a new area meeting the federal definition of a wetland was discovered in the path of the turnpike.

The waters are clear and there is great diversity of underwater flora and fauna, including flourishing coral formations. The island vegetation is mainly low, small plants such as grasses and herbs. Seabirds include the white bellied booby, terns, frigates, jays and woodpeckers. Charles Darwin visited the archipelago in 1830 and was impressed by the variety of species, including birds, lizards and spiders.

Nesting colony of Montezuma oropendolas Though most birds nest individually, some species—including seabirds, penguins, flamingos, many herons, gulls, terns, weaver, some corvids and some sparrows—gather together in sizeable colonies. Birds that nest colonially may benefit from increased protection against predation. They may also be able to better utilize food supplies, by following more successful foragers to their foraging sites.
|
|
Plymouth Beach is also an important breeding and nesting site for several threatened and endangered shorebirds, including the piping plover and the least, Arctic, common and roseate terns. The beach is a critical checkpoint in migratory birds flight. The birds stop at Plymouth beach to rejuvenate. The birds' routes typically span up to 3,000 miles (4,858 km) of non-stop flight.

Little Tobago Red-billed tropicbird nest on Little Tobago. Little Tobago (or Bird of Paradise Island) is a small island off the northeastern coast of Tobago, and part of the Republic of Trinidad and Tobago. The island supports dry forest. It is an important breeding site for seabirds such as red-billed tropicbird, Audubon's shearwater, brown booby, brown noddy, sooty and bridled terns.

The island is part of the Stewart B. McKinney National Wildlife Refuge and has the fifth-largest colony of nesting roseate terns in the northeastern United States. Much of the island's land mass has been lost to erosion, down to about from its original . The United States Army Corps of Engineers reinforced the eastern boundary to slow the advancing deterioration.

Goose Island provides habitat for seabird species such as black- faced cormorants, little penguins, pied cormorants, pied oystercatchers and sooty oystercatchers. Crested terns and silver gulls also inhabit and breed on the island. Reptiles recorded included marbled geckoes, three species of skink, sleepy lizards (Tiliqua rugosa) and tiger snakes (Notechis scutatus). The island is also a haul out area for Australian sea lions.
|
|
The large number of visitors at coastal sites sometimes has negative effects. Wildlife may be disturbed, a frequent difficulty for species that breed in exposed areas such as Ringed Plovers and Little Terns, and also for wintering geese. Plants can be trampled, which is a particular problem in sensitive habitats such as sand dunes and vegetated shingle.Liley (2008) pp. 10–14.
|
|
An exception is the brown noddy, which sometimes harbours protozoa of that genus. In 1961 the common tern was the first wild bird species identified as being infected with avian influenza, the H5N3 variant being found in an outbreak involving South African birds. Several species of terns have been implicated as carriers of West Nile virus.Takken & Knols (2007) p. 137–140.

There are Atlantic salt flats which fringe on the blanket bog, particularly in the lower reaches of the bay. Species growing here include sea thrift, sea arrowgrass, sea plantain, common salt marsh grass, Juncus gerardii, Juncus maritimus and turf fucoids. The bay supports breeding terns of several varieties and black-headed gulls, including the red- breasted merganser and sand martin.
|
|
The Seekonk River is home to numerous fauna that either migrate to the bay at some point during the year or live there year-round. There are several species of fish, shellfish and crab that have been documented. Birds include Loon, Cormorants, Herons, Gulls, Terns, Swans and Geese. Numerous flora also make the Seekonk River their home both on land and underwater.

In the mud at the bottom, scientists have discovered crustaceans that they believe are indigenous to the bay. Trysfjord has several islands and islets. The islets of Storholmen, Notholmen, and Urholmen lie just outside of Røsstad. Near the villages of Trysnes and Lastad lies the island of Lastadholmen which in recent years has had the largest colony of terns in Southern Norway.

Aleutian terns usually forage in shallow water, including tidal rips, along rivers, and over inshore marine waters. Occasionally adults and fledgling juveniles catch insects by hawking over freshwater ponds. This species can forage in nearshore marine waters up to offshore from Seward Peninsula, and up to offshore from other colonies. Individuals occasionally attempt to steal fish from other adults bringing fish to chicks.
|
|
Cemaes has a range of wildlife from foxes and peregrine falcons to marine life. On Wylfa Head, you can see porpoises coming up for air. Cemaes harbour is a good spot for fishing, as you can catch Atlantic mackerel, flatfish, red crabs and other fish and crustaceans. Near Cemaes is Cemlyn, which hosts the only breeding Sandwich terns in Wales.

Dalkey Island is home to a colony of seals, and a herd of wild goats also lives on the island. Birdwatch Ireland have established a colony of Roseate Terns on Maiden Rock just north of Dalkey Island. A pod of three bottlenose dolphins also frequents the waters around Dalkey Island. There are red squirrels and sparrow hawks on Killiney Hill.
|
|
The island provides habitat for a rich array of animals and birds. Native animals include deer, bears, beavers, red fox, rabbits and raccoons. More rarely seen are moose, coyotes and wolves. The coastal waters and inland lakes provide ideal habitat for loons, eagles, owls, songbirds, osprey, sandpipers, caspian terns, sandhill cranes, blue herons, blue jays, turkey vultures and many species of duck.
|

Ipswich sparrow, rough-legged hawk, and short-eared owl spend winter at the refuge. In late spring and summer the beach hosts piping plover, and common and least terns (protected by the Endangered Species Act) as well as sandpiper and other shorebirds. The eastern hognose snake, a New York State designated species of special concern, can still be found on the refuge.
|
|
It supports nationally important breeding populations of common tern. Roseate terns returned to the site after an absence of six years with two breeding pairs recorded in 1997. It has also supported nationally important numbers of Arctic tern. It also qualified under Criterion 3c for supporting internationally important breeding populations of Sandwich tern and of overwintering light-bellied brent geese.
|

The royal tern typically feeds in small secluded bodies of water such as estuaries, mangroves, and lagoons. Also, but less frequently, the royal terns will hunt for fish in open water, typically within about off the shore. The royal tern feeds in salt water and on very rare occasions in fresh water. When feeding they fly long distances from the colony to forage.
|
|
The Forster's tern feeds by plunge-diving for fish, but will also hawk for insects in its breeding marshes. It usually feeds from saline environments in winter, like most Sterna terns. It usually dives directly, and not from the "stepped-hover" favoured by the Arctic tern. The offering of fish by the male to the female is part of the courtship display.
|
|
In winter, the forehead becomes white and a characteristic black eye mask remains. Juvenile Forster's terns are similar to the winter adult. The call is a harsh noise like a black-headed gull. This species is unlikely to be confused with the common tern in winter because of the black eye mask, but is much more similar in breeding plumage.
|
|
Weather is the main explanation for nest failure and egg loss. Unsheltered nests are more prone to destruction than sheltered one. Nest made on higher ground are also more shielded from flooding but are more exposed to the wind. Forster's Terns have been recorded using man-made platforms, most notably in Wisconsin, where they were built to substitute for the Cat Island Chain.
|

The subspecies that lived on La Digue is extinct. From the arthropod group there is, for example, the Seychelles coconut crab which likes to dig holes in the backyards of the Seychellois people. Among others, there are fodys, sunbirds, terns, fruitbats, sheath-tailed bats, and geckos. The reefs and lagoons of La Digue offer a large amount of flora and fauna.
|
|
Juvenile bridled terns are scaly grey above and pale below. This species is unlikely to be confused with any tern apart from the similarly dark-backed sooty tern and the spectacled tern from the Tropical Pacific. It is paler-backed than that sooty, (but not as pale as the grey-backed) and has a narrower white forehead and a pale neck collar.

Saunders was an expert on gulls and terns. Among other duties, he wrote about the gull specimens from the Challenger expedition of 1872–1876. Saunders served as secretary of the British Ornithologists' Union from 1901 to 1907, and first secretary and treasurer of the British Ornithologists' Club. He was also an active member of the Zoological, Linnean and Royal Geographical Societies.

Retrieved on 2007-09-28. While sometimes detrimental to seabird habitat, management of tree mallow (both planting and thinning) has been successfully employed to shelter nesting sites of the threatened roseate tern, which requires more coverage than common terns to impede predation.Du Feu, Chris. (February 2005.) Nestboxes: Extracts from British Trust for Ornithology Field Guide Number 23 with some additions and amendments.

The islands have been colonized by large numbers of breeding birds. A colony of 200 breeding pairs of Pied avocet has made the islands their home, as has a large colony of Common tern. Little terns also breed on the islands. Northern shoveler, Gadwall, Garganey, Mediterranean gull, Spoonbill, and numerous other species of birds have been seen on and around the islands.

Grazing by rabbits maintains a short sward, which is desirable for the fledglings. Great Copeland has an internationally important Arctic tern colony, with some 550 pairs. The site now represents the largest colony for this species in Ireland. Mew Island has been an important tern colony in the past and it is hoped that positive management will encourage terns to become re-established.

In Argentina, dusky dolphins associate closely with southern right whales and South American sea lions. They have been found around bottlenose dolphins, but apparently do not interact with them, and may share feeding areas with Risso's dolphins. They also associate with various seabirds, such as kelp gulls, cormorants, terns, shearwaters, petrels, and albatrosses. In New Zealand, dusky dolphins mingle with common dolphins.

Today, it is limited almost exclusively to sport boats and pleasure cruisers. To the north is the Zingster Strom, the river- like section of the bodden south of Zingst. Here the bodden reaches its greatest depths of over six metres. To the northwest lie the well-known islands of Kirr and Barther Oie, both important breeding areas for gulls, terns, waterfowl and waders.

There is also some geographical variation, Californian birds often being in non- breeding plumage during migration. Juvenile common terns have pale grey upperwings with a dark carpal bar. The crown and nape are brown, and the forehead is ginger, wearing to white by autumn. The upperparts are ginger with brown and white scaling, and the tail lacks the adult's long outer feathers.

Although not a true hover, some birds remain in a fixed position relative to the ground or water by flying into a headwind. Hummingbirds, kestrels, terns and hawks use this wind hovering. Most birds that hover have high aspect ratio wings that are suited to low speed flying. Hummingbirds are a unique exception - the most accomplished hoverers of all birds.
|
|
The site has been identified as an Important Bird Area by BirdLife International mainly because, between April and September, it is an important nesting and roosting site for least terns. Other wetland birds which breed at the site include white-cheeked pintails, black-necked stilts, snowy plovers and willets. Breeding land birds include restricted-range green-throated caribs and Caribbean elaenias.

Coconut palms planted by the guano diggers did not thrive, although a few dilapidated trees may still be seen. Introduced weeds, including the low- growing woody vine Tribulus cistoides, now dominate extensive open areas, providing increased cover for young sooty terns. Malden is an important breeding island for about a dozen species including masked boobies (Sula dactylatra), red-footed booby (Sula sula), tropicbirds (Phaethontidae), great frigatebird (Fregata minor), lesser frigatebird (Fregata ariel), grey-backed tern (Onychoprion lunata), red-tailed tropicbird (Phaethon rubricauda), sooty terns (sterna fuscata) It is also an important winter-stop for the bristle- thighed curlew (Numenius tahitiensis), a migrant from Alaska; and other migratory seabirds (nineteen species in all). Two kinds of lizards, the mourning gecko (Lepidodactylus lugubris) and snake-eyed skink (Cryptoblepharus boutonii) are present on Malden, together with brown libellulid dragonfly.

The dominant feature of the locality is the eponymous lagoon. The lagoon can cover several miles in wet seasons, and is "intensely salty". It is used by "many thousands of water birds, pelicans, great cormorants, whiskered terns and silver gulls" at certain times of year. In the late nineteenth and early twentieth century, it was a popular alternate "seaside" attraction, with visitors coming from across the district.

The ten units of Stewart B. McKinney NWR include a variety of habitats from grassy upland, to tidal salt marsh. Native wildlife populations have diverse habitat requirements. Each species, from roseate terns to American black ducks, has very different needs for food, water, shelter and space. The refuge units along Connecticut's coast fill these needs by providing habitats that are forested, marshy, sandy and secluded island habitats.

Only the modern megapodes and the little tern exhibit a comparable degree of embryonic ossification in the arm and shoulder bones. It is likely that Gobipipus hatchlings, like megapodes and little terns, would be able to fly very soon after hatching. No embryos are known from G. major eggs, but they are usually assumed to have been laid by a similar type of bird.

Loons, diving ducks, penguins and auks pursue their prey underwater, using their wings or feet for propulsion, while aerial predators such as sulids, kingfishers and terns plunge dive after their prey. Flamingos, three species of prion, and some ducks are filter feeders. Geese and dabbling ducks are primarily grazers. Some species, including frigatebirds, gulls, and skuas, engage in kleptoparasitism, stealing food items from other birds.

Young birds bear grey and brown scalloped plumage on their backs and wings. It is a vocal bird. It nests in a ground scrape and lays one to three eggs. Like all Thalasseus terns, the Sandwich tern feeds by plunge diving for fish, usually in marine environments, and the offering of fish by the male to the female is part of the courtship display.
|
|
Fledged juveniles are fed at the nest for about five days, and then accompany the adults on fishing expeditions. The young birds may receive supplementary feeds from the parents until the end of the breeding season, and beyond. Common terns have been recorded feeding their offspring on migration and in the wintering grounds, at least until the adults move further south in about December.

Where numerous large animals are present, cattle egrets selectively forage around species that move at around 5–15 steps per minute, avoiding faster and slower moving herds. The cattle egret may also show versatility in its diet. On islands with seabird colonies, it will prey on the eggs and chicks of terns and other seabirds. During migration it has also been reported to eat exhausted migrating landbirds.

Terns are generally long-lived birds, with individuals typically returning for 7–10 breeding seasons. Maximum known ages include 34 for an Arctic tern and 32 for a sooty. Although several other species are known to live in captivity for up to 20 years, their greatest recorded ages are underestimates because the birds can outlive their rings. Interbreeding between tern species is rare, and involves closely related species when it occurs.

A close relative of the bridled and sooty terns (with which it is sometimes confused), the spectacled tern is less common than the other members of its genus and it has been studied less. The three species, along with the Aleutian tern were recently split into a new genus Onychoprion from Sterna (Bridge et al., 2005). They resemble the sooty tern but with a grey back instead of a black one.
|
|
Onychoprion aleutica has not been thoroughly studied yet. If its winter migratory range was completely unknown until the late 1980s; it is now known that many Aleutian terns spend the winter near the Equator in the western Pacific. The Aleutian tern breeds in wide-ranging coastal colonies only in Alaska and eastern Siberia. Although Alaskan and Siberian populations are not well monitored, both are thought to be in significant decline.
|
|
Their color ranges from a clay/olive green to a honey yellow, they tend to be darker than eggs of other terns. Distinctive large and smaller black spots are irregularly marked over the egg. After a three-week incubation period, the eggs hatch from early June until late July. Several days after hatching, young birds move to taller vegetation before moving with adults to staging areas along coast (semiprecocial juvenils).
|
|
The terrestrial vegetation on the island is limited because of the high number of seabirds. The island is almost treeless and is covered by grasses and other low-growing plants. It has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a breeding population of 430,000 pairs of sooty terns, and a large number of boobies. Green and hawksbill sea turtles also nest there.

This small sea bird is well known for laying a single speckled egg on exposed thin branches in a small joint or depression without a nest. The thin branches it chooses is act of predator-avoidance behavior, crows (Corvus splendens maledivicus) and even rats avoid sitting or climbing small branches. However, terns are vulnerable to strong winds and the chicks have sophisticated sharp clawed feet to cling on fragile branches.

Forster's terns tend to nest in marshy areas, either in freshwater or in estuaries. The nests are usually located deep within the marsh, either on tidal islands or evaporation pond islands, but also on manmade dikes. Nests are composed of adjacent marsh vegetation. Many nests are considered floating and are made of marsh grasses, then can be set on top of the vegetation or deposited on floating rafts of vegetation.

Wildlife may be disturbed, a frequent difficulty for species that breed in exposed areas such as ringed plovers and little terns, and also for wintering geese. Plants can be trampled, which is a particular problem in sensitive habitats such as sand dunes and vegetated shingle.Liley (2008) pp. 10–14. The limited access to the island means that it is not subjected to the pressures of heavy or uncontrolled visitor access.

The Goose Lake Valley is on the western flyway from Mexico to bird breeding grounds in the Arctic. During the spring, Canada geese, snow geese, Ross' geese, and whistling swans stops in the valley to feed and rest before continuing north. Numerous shorebirds also migrate through the valley. These include black-necked stilts, American avocets, spotted sandpipers, Wilson's phalaropes, red-necked phalaropes, black terns, eared grebes, horned grebes, and cinnamon teal.

The coast and offshore islands are home to gulls, terns and cormorants. The mountainous north of the country attracts many passerines in passage, the desert areas are home to the endangered houbara bustard, sand partridge, four species of sandgrouse, desert larks, pipits, wheatears and buntings. The mountains additionally attract golden eagles and Egyptian vultures. The Dhofar region in the south has a great variety of breeding and migratory species.

The Ross's gull breeds in small colonies on tundras and swampy Arctic estuaries, often nesting with other seabirds such as Arctic terns. It lays two to three eggs in a nest on the ground lined with seaweed, grass or moss, often on an island in a little lake. The eggs are olive green with small reddish-brown spots. Incubation takes about three weeks and the chicks fledge in another three weeks.

Because of the tract's location in the Pacific Flyway, a large variety of waterfowl inhabit it, especially during the fall and winter. Year round species include gulls, great blue herons, terns, swallows, crows, blackbirds, cormorants and kingfishers. Hunting on the open water is allowed, subject to California Fish & Wildlife Department (CDFWD) regulations. Permits and other arrangements must be made in advance through the Brannan Island State Recreation Area.

The results of this rich source of nutrients are visible everywhere. Commonly seen along the beaches and the adjacent maritime forests are several species of shorebirds, including egrets, herons, white ibis, gulls, terns, plovers, sandpipers, pelicans, and ospreys. Local birds of prey include vultures, hawks, and the southern bald eagle. Five of the eighteen sites along Georgia's Colonial Coast Birding Trail are located within the Golden Isles/Glynn County.

The more abundant species of fish in the waters include: Mediterranean parrotfish (Sparisoma cretense), moray eel, anchovy, grouper, wrasse, in addition to crabs and limpets. Marine and terrestrial birds vary throughout the year, influenced by migratory patterns and climate. In addition to local terns, shearwaters and herons, the fajã is visited by wagtails, sparrows and common blackbird (Turdus merula) throughout the year, with other species arriving in the summer months.

This species breeds in colonies on lakes, marshes and coasts. It nests in a ground scrape and lays two to five eggs. While widely distributed in freshwater areas in Eurasia, it is associated almost solely with saltwater, coastal areas in North America. This is a somewhat atypical tern, in appearance like a Sterna tern, but with feeding habits more like the Chlidonias marsh terns, black tern and white-winged tern.

A previous paper details four early claims of red-necked stint, none of which were acceptable. As of 2007, records of Wilson's snipe (from 1985 and 1998),Mitchell, Dominic, editorial comment in response to Mike Buckland (2007) Wilson's on the record Birdwatch 185:20–21 elegant terns (from 2002), a number of eastern whitethroats and lesser whitethroats, and several apparent North African common chaffinches, are still under consideration.

Tern's eyes are not particularly ultraviolet sensitive, an adaptation more suited to terrestrial feeders like the gulls. An adult bringing a sand eel to a juvenile at Nantucket National Wildlife Refuge The common tern preferentially hunts fish long.Sandilands (2005) pp. 157–160. The species caught depend on what is available, but if there is a choice, terns feeding several chicks will take larger prey than those with smaller broods.

The ruddy turnstone will take eggs from unattended nests, and gulls may take chicks. Great horned owls and short-eared owls will kill both adults and chicks, and black-crowned night herons will also eat small chicks. Subscription needed for full text. Merlins and peregrine falcons may attack flying terns; as with other birds, it seems likely that one advantage of flocking behaviour is to confuse fast- flying predators.

Whimbrel at Muzhappilangad Beach Lesser crested terns Ruddy turnstone Despite a tourist destination the beach is a bird watching hotspot too. More than thirty species of migratory birds visit here in the winter. Among them Pectoral sandpiper and Caspian plover, sighted here in 2013 were reported for the first time in Kerala. Long, broad shore and rocky formations on the either side of the beach provide a safe place for migration.

After young chicks are three days old, they are brooded less frequently by parents and require wind blocks and shade, and protection from predators. In some colonies in southern California, Spanish roof tiles are placed in colonies so chicks can hide there. Notable disruption of colonies can occur from predation by burrowing owls, gull-billed terns and American kestrels. Depredation by domestic cats has been observed in at least one colony.

This bird feeds on fish, carrion, scraps, smaller birds up to the size of common gull and rodents, especially lemmings. It robs gulls, terns and even gannets of their catches. Like most other skua species, it continues this piratical behaviour throughout the year, showing great agility as it harasses its victims. Only the Great Black Backed Gull, White- Tailed Eagle and Golden Eagle are known to take adult, healthy pomarine skuas.

The Story of Loch Fleet National Nature Reserve. p. 12-13. Breeding birds at Loch Fleet include Arctic terns, common terns, oystercatchers, ringed plovers, wheatears, stonechats, cuckoos, meadow pipits and skylarks, these species tending to favour the links habitat. The pinewoods hold species including crossbills, siskin, redstart, treecreeper, great spotted woodpecker, buzzard and sparrowhawk. Loch Fleet is a good place to see osprey fishing, and in the early 1990s there were 10 breeding pairs of breeding on the wider SPA.The Story of Loch Fleet National Nature Reserve. p. 12-13. The most visible mammals at Loch Fleet are seals: common seals can be seen from the public road at Skelbo year round, and grey seals visit during the winter months. Otter and pipistrelle bats are also found here, along with other typical Scottish land mammals such as roe deer, fox, pine marten, and weasel. Red squirrels and Scottish wildcats have been recorded in the area, but have not been seen in recent years.

Gantlett's specialism as an ornithologist is the advancement of bird identification. Among the areas of knowledge in which Gantlett has played a key role are the identification of orange-billed terns. He also found the UK's first Rock Sparrow at Cley on 14 June 1981 (with Richard Millington), still the only record in the UK. He has published papers on this subject in Birding World and in British Birds.Gantlett, S.J.M. Lesser Crested Tern in Norfolk.

The spit has a short sloping shelf that drops off steeply at about 40–2000 metres in depth within of the reef. Three small cayes: North Silk, Middle Silk and South Silk, lie south of Gladden entrance just inside Queen Caye. A nesting colony of terns has been recorded on North Silk Caye. The reserve contains some of the healthiest parts of the reef system due to its elevation and good water quality.

Smaller species are less closely packed and mob intruders. Peruvian and Damara terns have small dispersed colonies and rely on the cryptic plumage of the eggs and young for protection. The male selects a territory, which he defends against conspecifics, and re-establishes a pair bond with his mate or attracts a new female if necessary. Courtship involves ritualised flight and ground displays, and the male often presents a fish to his partner.

Least terns and snowy plovers nesting at Batiquitos Lagoon Wintering locations are actually unknown, but suspected to include the South American Pacific Coast. The California least tern arrives at its breeding grounds in late April. Courtship typically takes place removed from the nesting colony site, usually on an exposed tidal flat or beach. Only after courtship has confirmed mate selection does nesting begin by mid-May and is usually complete by mid-June.

The auks are a family of seabirds related to the gulls and terns which contains several genera. The common murre is placed in the guillemot (murre) genus Uria (Brisson, 1760), which it shares with the thick-billed murre or Brunnich's guillemot, U. lomvia. These species, together with the razorbill, little auk and the extinct great auk make up the tribe Alcini. This arrangement was originally based on analyses of auk morphology and ecology.

The New Zealand fairy tern was noted as being common in the late 19th century. However, these records have been suggested as inaccurate as the birds can be difficult to distinguish from little terns. From 1940 to 1983, the New Zealand fairy tern was known to have bred at several sites along the northern coastline of the North Island. Their breeding range extended from Ruakaka, in Northland, to Tauranga in the Bay of Plenty.

About 60 species are mainly summer visitors which breed in Britain but winter further south, mainly in Africa. A large number of these are insectivores such as warblers, flycatchers and common cuckoo, as would be expected from the scarcity of insects in British winters. Several seabirds move out to sea after breeding, and terns and some auks are absent during the winter months. In 2007, 16 million birds flew from Africa to Britain.

They have white plumage including a thick layer of down, with only the face and leg colours distinguishing the two species. They look plump and dove-like, but are believed to be similar to the ancestors of the modern gulls and terns. There is a rudimentary spur on the "wrist" (carpal) joint, as in plovers. The skin around the eye is bare, as is the skin above the bill, which has carbuncular swellings.

100px The birds forage for food by flying low over the water with the bill open and the lower mandible skimming through the water. When a fish is encountered, it moves up the lower mandible and the bird raises the upper mandible and snaps it with a movement of the head. They forage in small flocks and often associate with terns. They feed mainly on fish but also take small crustaceans and insect larvae.
|
|
The eggs are buff or white with brown blotches and streaks. There are three to five eggs in a clutch. They may indulge in a low- level of inter-specific brood parasitism, laying their eggs in the nests of river terns (Sterna aurantia). The birds tend to incubate the eggs more during the cooler hours of the day and are often away from the nest during the hotter parts of the day.

A pair of masked boobies (Sula dactylatra) calling on Malden Island Grey-backed terns flying over Malden Island with lagoon in background Because of Malden's isolation and aridity, its vegetation is extremely limited. Sixteen species of vascular plants have been recorded, of which nine are indigenous. The island is largely covered in stunted Sida fallax scrub, low herbs and grasses. Few, if any, of the clumps of stunted Pisonia grandis once found on the island still survive.

On the breeding grounds they can be heard making yelping and rattling sounds. Outside of the breeding season they spend most of their time over open ocean and have a harsh kreeah cry. This bird feeds on fish (mainly caught from other seabirds), smaller birds, food scraps, small mammals, fruit and carrion. On migration, long-tailed jaegers are more likely to catch their own food, and less likely to steal from gulls and terns than larger species.

The erosion control project was completed, but Hurricane Irene and Hurricane Sandy greatly reduced the breeding habitat of the terns to just . Erosion threatens the island's very existence, it is believed that it was around eight acres in 1639 before being reduced to 5.70 acres by 1818. By 1987, the total area has fallen to 2.87 acres and it was projected that it could lose another 12 inches each year until the lighthouse crumbles into the sea around 2026.

The vegetation is dominated by coconut-palms and Casuarina equisetifolia trees. It is used as a support base for the harvesting of sooty tern eggs on neighboring Desnoeufs Island during the nesting season from June to August. Marie Louise has been identified as an Important Bird Area (IBA) by BirdLife International because it supports breeding colonies of brown (2000 pairs) and lesser noddies (3500 pairs), and white terns (3000 pairs). Green and hawksbill sea turtles also nest there.

Greater crested tern displaying in Tasmania. The suborder Lari is the part of the order Charadriiformes that includes the gulls, terns, skuas and skimmers; the rest of the order is made up of the waders and snipes. The auks are now placed into the Lari too, following recent research. Sometimes, the buttonquails are also placed here, but the molecular data and fossil record rather suggests they are a quite basal offshoot along with the snipe-like and aberrant waders.

On the island are Steller's eider (Polysticta stelleri), the key bird species, and razorbill (Alca torda). Other breeding species recorded are: Mute swan (Cygnus olor), greylag goose (Anser anser), tufted duck (Aythya fuligula), gadwall (Anas strepera), black guillemot (Cepphus grylle), razorbill (Alca torda), guillemot (Uria aalge), water rail (Rallus aquaticus), colonies of gulls (Larus spp.), terns (Sterna spp.) and the white-tailed eagle (Haliaeetus albicilla). Despite harsh conditions, the vegetation on the island is fairly diverse.

North Uist has many prehistoric structures, including the chambered cairn, the stone circle, the standing stones, the islet of (which may be the earliest crannog site in Scotland), and the roundhouses, which were exposed by storms in January 2005. The Vikings arrived in the Hebrides in AD 800 and developed large settlements. The island is known for its bird life, including corncrakes, Arctic terns, gannets, corn buntings and Manx shearwaters. The RSPB has a nature reserve at Balranald.

The marshes and tidal muds offer a variety of wildlife habitats, which are important for gulls and terns in spring/summer and waders and wildfowl in autumn/winter. At Pennington Marshes, there are several lagoons, situated just inside the seawall - at the western end is Fishtail Lagoon, and the east of that Butts Lagoon. A number of rare vagrant birds have occurred at the marshes including a stilt sandpiper in 2002, and a lesser sand plover in 2003.

Refuge islands provide habitat for common, Arctic, and endangered roseate terns; Atlantic puffins; razorbills; black guillemots; Leach's storm- petrels; herring, greater black-backed, and laughing gulls; double-crested and great cormorants; and common eiders. Over the last 25 years, the Service has worked to reverse the decline in these birds' populations. As a result, many species have returned to islands where they nested historically. In addition to seabirds, wading birds and bald eagles nest on refuge islands.

Mingo NWR Mingo's primary goal is to protect wilderness resources and critical habitat for migratory waterfowl. Located in the center of the busy Mississippi Flyway, the refuge serves as an important resting and feeding area for migratory birds heading south. In addition to resident waterfowl species, Mingo provides for migrating ducks, geese, shorebirds, gulls, terns, loons, grebes, pelicans, cormorants, herons, bitterns, ibises, rails, coots, and swans. Over 95 species of migratory waterfowl have been seen at Mingo.

Numerous other birds can be seen, especially during the spring and autumn migration. Sand martins (Riparia riparia) arrive early and can usually be seen hawking over the water for insects in the second or third week of March. Flocks of tits (Paridae), swallows (Hirundinidae) and terns (Sternidae) can regularly be seen. Waders, such as lapwings (Vanellus vanellus), dunlin (Calidris alpina) and common snipe (Gallinago gallinago), are attracted to the muddy shores if the water level drops in autumn.

There are large breeding colonies of grebes and brown-headed gulls, and some strip geese, rust geese and terns. In the vicinity of the lake black-necked cranes and Tibetan grouse are relatively common. The basin of the Tso Kar and the adjoining More Plains constitute one of the most important habitats of the kiang, Tibetan gazelles, Tibetan wolves and foxes; there are himalayan marmots in the higher reaches. Yaks and horses are kept by the nomads.

FOLIA ZOOLOGICA-PRAHA-, 51(3), 205-214. Outside of aforementioned families other infrequently taken bird prey has included cuckoos, nightjars, sandpipers, terns, rollers and hoopoes. Due likely in no small part to the scarcity of herpetological prey diversity in the temperate and often frigid haunts of Ural owls, reptiles are very infrequent prey for this species. However, sometimes frogs may be taken when an Ural owl opportunes upon one in the warmer months of the year.

Mamelles Island is a granite island with a length of , a width of , covered with little vegetation. The fauna of the island is represented only by wild rabbits and sea birds, including terns, which nest on the island. The name of the island comes from the French word «mamelles», which means "breast". This strange island was called because of its shape - two high hills in the south and the north, and a relatively deep hollow between them.

A large colony, dominated by lesser noddies, but including about 1300 pairs of brown noddies, is present from May to September during the south-east monsoon. During the north-west monsoon, the hill supports a breeding colony of wedge-tailed shearwaters. Year-round breeders include white and bridled terns, white-tailed tropicbirds and some 1000–1,500 pairs of Audubon's shearwaters. Several hundred great and lesser frigatebirds use the island for roosting and can be seen soaring over it.

There are brown snakes and skinks in dense bushes along the top of the embankments. Each year in late summer thousands of black swans and ducks descend on the area as the inland waterways they inhabit dry up. Waterbirds such as pelicans, cormorants, oyster catchers and terns are common often year round. Egrets, ibis, herons and spoonbills feed on the seagrass and fairy wrens, chats, fantails and thornbills feed on insects and plants amongst the samphire.

Of crustaceans, Norway lobster, and deep-water prawns and brown shrimp are commercially fished. The coasts provide breeding habitat for dozens of bird species. Tens of millions of birds make use of the North Sea for breeding, feeding, or migratory stopovers every year. Populations of northern fulmars, black-legged kittiwakes, Atlantic puffins, northern gannets, razorbills, and a variety of species of petrels, seaducks, loons, cormorants, gulls, auks, and terns, and other seabirds make these coasts popular for birdwatching.

The lake supports 57 species of avifauna, of which 6 are migratory and 51 resident species. It is also reported that about 40 species of wetland-dependent birds are recorded in the lake, out of which 45% are long-distance migrants. Terns, plovers, cormorants, and herons are most abundant birds in the lake. A study report has identified 45 insect species, including 26 species of butterfly, 5 odonates, 9 hymenopteras, and 2 orthopterans, 1 hemipteran and 2 coleopterans.

Buck Island National Monument is one of few places in the Virgin Islands where brown pelicans and threatened least terns nest. Buck Island Reef National Monument (Note that the photograph is taken from an unusual perspective. The beach is in fact to the west end of Buck Island and in this photograph north is facing downward). Most of the Monument area, which is administered by the National Park Service, is underwater and attracts around 50,000 visitors a year.

When the ice sheet melted with the rising temperatures 10,000 years ago the basin was uncovered and was flooded by the sea, forming the loch that is seen today. Since the end of the last ice-age the sea has continued to change the loch by erosion and deposition. The loch has a sandbank on its western shores called 'the Scar'. This bank, just south of the village of Kirkcolm, is an important breeding ground for terns.

A selection of croats from the Museu de Prehistòria de València The croat was a silver coin of Catalonia introduced by Peter III of Aragon in 1285 and minted at Barcelona. The term "croat" derives from the Latin grossus denarius, great coin, a common term for silver coins of higher value than pennies. Peter III was inspired by the gros introduced by Louis IX of France. The croat was originally worth twelve terns of 25% silver billon.

Common terns adapt readily to artificial floating rafts, and may even nest on flat factory roofs. Unusual nest sites include hay bales, a stump above the water, and floating logs or vegetation. There is a record of a common tern taking over a spotted sandpiper nest and laying its eggs with those of the wader. Outside the breeding season, all that is needed in terms of habitat is access to fishing areas, and somewhere to land.

Arctic terns are long-lived birds that spend considerable time raising only a few young, and are thus said to be K-selected. The bird has life span that was thought be around 20 years, however National Geographic, The University of Alberta & Massachusetts Institute of Technology, concluded in 2010 that more than 50% of this species will live past their 30th birthday. A 1957 study in the Farne Islands estimated an annual survival rate of 82%.

The Tabusintac Lagoon and River Estuary is a wetland in Alnwick Parish, Northumberland County, in north-eastern New Brunswick, Canada. It was classified as a wetland of international importance on June 10, 1993. It is also a globally significant Important Bird Area for the population of common terns, and shorebirds in general, that it supports. Primarily a shallow coastal estuary with gentle slopes, the 50 km2 site is underlain by various sedimentary rocks, including red sandstone and shale.

Wildlife is rich and varied, with an immense amount of Arctic cod (30,000 tons worth) known to exist there. The Arctic cod is also part of the diet for many of the birds in Lancaster Sound and marine mammals. Many narwhal, beluga, bowhead whale (an endangered species), ringed, bearded and harp seals, walrus, polar bears, thick-billed murres, black-legged kittiwakes, northern fulmars, black guillemots, Arctic terns, ivory gulls and snow geese all occupy the area.

Scarecrow Island is a small, 7-acre (0.03-km²) island in Lake Huron. It forms the southern limit of Thunder Bay and helps define the harbor of Alpena, Michigan. It is part of Sanborn Township, in Alpena County, Michigan. In recognition of Scarecrow Island's importance as a traditional nesting site for colonial waterbirds such as cormorants, herons, gulls, and terns, it received protection as one of eight islands in the Michigan Islands National Wildlife Refuge in 1943.

Dikes encircle the island, which is about , and one can walk around it in an hour. Salt marshes (the "Outland"), lie outside the dikes and provide a hatchery for birds such as oystercatchers, scrays, sandwich terns, black-headed gulls, herring gulls, and others. During the summer farmers may pasture cows and horses on the northern Outland. 250px At low tide one can reach the island on foot or on a Wattwagen, a horse-drawn mud flat coach, from Cuxhaven.

Nizki's shoreline is very irregular and is fringed by numerous rocks, reefs, and kelp-marked shoals.U.S. Coast Pilot 9, Chapter 7, Aleutian Islands Foxes were introduced to Nizki Island by Russian fur traders in the 19th century. This decimated the population of many bird species on the island. The last fox was removed from Nizki Island in 1976, and now Aleutian Canada Geese (once believed to be extinct), Puffins, and Aleutian Terns are common on the island.

The protected territory ASPA 126 Byers Peninsula has been identified as an Important Bird Area (IBA) by BirdLife International because it supports breeding colonies of Antarctic terns (1760 pairs) and kelp gulls (450 pairs). Other birds nesting on the peninsula include chinstrap and gentoo penguins, Wilson's and black-bellied storm petrels, Cape petrels, southern giant petrels, imperial shags, brown skuas and snowy sheathbills. Large numbers of southern elephant seals haul out during their breeding season.Byers Peninsula, Livingston Island.

Sprogø. Sprogø is 154 acres, and is located centrally in the Great Belt. It connects the two halves of the Great Belt Bridge, and the large amount of traffic caused by that limits the amount of wildlife found on the island. Despite that, the island is a popular breeding spot for many species of gulls and terns. The three Danish species of swallows thrive on the island, making home in the buildings and the lighthouse on the island.

The million or so sooty terns in the Seychelles prove that there is safety in numbers and the nearby predatory egrets have little success when attempting to steal. The behaviour of Arabian babblers is more akin to that of a troop of monkeys: they do everything for the benefit of a group as a whole. Eventually the day will come when flight beckons, and the grown bird will leave the nest to start a family of its own.
|
|
Many other birds are known to engage in hawking as an opportunistic feeding technique or a supplemental source of nutrition: among these are the cedar waxwing, which mostly eats fruit but is also often observed hawking insects over streams; terns of the genus Chlidonias, such as the black tern, fly in search of insects, sometimes chasing after dragonflies in flight; and even large owls that normally feed on rodents will snatch flying insects when the opportunity arises.

As the southeasternmost island in the Bahamian Commonwealth, Mayaguana is bordered to its east by deep waters of the Atlantic Ocean. Many underwater coral reefs are found off-shore, as well as shipwrecks. Mayaguana is home to the Bahamian hutia, a rodent that was thought to be extinct until the mid-1960s, as well as Bahamian flamingos, Bartsch's iguanas, plovers, terns, and osprey. Nesting sea turtles can be found throughout the undeveloped northern part of the island.

Seagull Lake is within the boundaries of an Important Bird Area (IBA) known as the Seagull Lake Important Bird Area. The IBA was identified by BirdLife International because it regularly supports a breeding colony of fairy terns. Potential threats to the colony are from disturbance by people, vehicles and dogs, water abstraction in the catchment, and fox predation. Other birds recorded using the lake are banded stilts, red- necked avocets, red-necked stints, red-capped plovers, sharp-tailed sandpipers and hooded plovers.

Birds of prey have a very high density of receptors and other adaptations that maximise visual acuity. The placement of their eyes gives them good binocular vision enabling accurate judgement of distances. Nocturnal species have tubular eyes, low numbers of colour detectors, but a high density of rod cells which function well in poor light. Terns, gulls and albatrosses are amongst the seabirds which have red or yellow oil droplets in the colour receptors to improve distance vision especially in hazy conditions.
|
|
Terns have a wide repertoire of vocalisations. For example, the common tern has a distinctive alarm, kee-yah, also used as a warning to intruders, and a shorter kyar, given as an individual takes flight in response to a more serious threat; this quietens the usually noisy colony while its residents assess the danger. Other calls include a down-slurred keeur given when an adult is approaching the nest with a fish, and a kip uttered during social contact.Hume (1993) pp. 68–75.

Many terns breeding in temperate zones are long-distance migrants, and the Arctic tern probably sees more annual daylight than any other animal as it migrates from its northern breeding grounds to Antarctic waters, a return journey of more than . A common tern that hatched in Sweden and was found dead five months later on Stewart Island, New Zealand, must have flown at least .Newton (2010) pp. 150–151. Actual flight distances are, of course, much greater than the shortest possible route.

The white tern is unique in that it lays its single egg on a bare tree branch. Tropical species usually lay just one egg, but two or three is typical in cooler regions if there is an adequate food supply. The time taken to complete the clutch varies, but for temperate species incubation takes 21–28 days. The eggs of most gulls and terns are brown with dark splotches, so they are difficult for predators to spot on the beach.
|
|
Terns have sometimes benefited from human activities, following the plough or fishing boats for easy food supplies, although some birds get trapped in nets or swallow plastic. Fishermen looked for feeding tern flocks, since the birds could lead them to fish shoals. Overfishing of small fish such as sand eels can lead to steep declines in the colonies relying on these prey items. More generally, the loss or disruption to tern colonies caused by human activities has caused declines in many species.

The rare Bahamian hutia is the only terrestrial mammal native to the Bahamas, and was introduced into the park in 1973. There are a number of seabirds that nest in the park, including Audubon's shearwater, white-tailed tropicbird, brown noddy and six species of terns (bridled, least, roseate, royal, sandwich and sooty). The endangered Allen Cays rock iguana (Cyclura cychlura inornata) is found on several islands in the Exumas. The coral reefs, marine invertebrates and many species of fish are also noteworthy.

The name Tarns comes from the Old Norse "tiorn", meaning a lake, and "tarn" is a word commonly used in northern England for a lake or pond. Such a lake is present at Tarns, giving the settlement its name. In the past, the name has been spelled as Ternis, Terns, and Tarnes. Tarns is a small settlement, and, in spite of appearing on local signposts, including on the B5300 coast road, it is not named on some contemporary mapping projects like Google Maps.

The mudflats are used by a wide variety of birds to feed on. Flocks of brent geese, Eurasian wigeon and Northern pintail use the estuary in the winter while waders such as dunlin, black-tailed godwit and grey plover feed on the mud and roost in the marshes and shingle ridges. sandwich and little terns nest on the shingle ridges alongside black-headed gulls. Together with great cormorants these fish eating birds hunt their prey in the rich waters of the area.

In South Africa spawning has been observed near estuaries and takes place from October to January. The eggs bear fine filaments which are used to adhere the eggs to the substrate or to other submerged surfaces. The hardyhead silverside is an important forage fish for larger fish species such as sharks, tunas, needlefish and amberjacks which capture them by associating with and attacking the day schools. They are also preyed on by sea birds such as terns, boobies, gulls, egrets and herons.

This species will place large food items close to crabs so that the crab will tear it into smaller pieces. Arrow gobies are prey for Sebastes, staghorn sculpin, whitespot greenling and terns. This species does not build a nest or provide any care for its offspring, and the eggs are dispersed into the water column. The underside of this goby is silvery, and when threatened, they use this to make a brief signal to other gobies before quickly taking refuge in the burrow.

The bustard, locally known as son chidiya or the golden bird and the blackbuck are the two important faunal species at the park, although bustards have not been spotted here since 1994. The Dihaliya lake within the park hosts migratory birds and the initial approval for denotification of the sanctuary required the establishment of a sanctuary consisting of the lake and the government land around it. 245 migrant species of avifauna including pintails, terns, spoonbills and teals have been recorded at Karera.

The royal tern's length ranges from and their average weight is anywhere from . The calls of the royal tern are usually short, clear shrills. Some of the shrills sound like kree or tsirr; the royal tern also has a more plover like whistle that is longer, rolling and is more melodious. In various parts of its range, the royal tern could be confused with the elegant tern, lesser crested tern (the other orange-billed terns), and the greater crested tern.

Point No Point has one of the largest birdlists of any site in Washington. The point is owned jointly by the U.S. Coast Guard (leased to Kitsap County) and a private landowner who is knowledgeable and sympathetic to birdwatchers. Point No Point is best known for its water-related species: gulls, cormorants, loons, terns, jaegers, ducks, grebes, mergansers, scoters, brant, and alcids. When the tide is running, there are flocks of Bonaparte's gulls and seabirds, often a veritable feeding frenzy.

Arctic skua (Stercorarius parasiticus) Grey seals on the Jökulsárlón lake The lake is filled with fish that drift in from the sea along with the tides. Seals gather in large numbers at the mouth of the lake to catch fish during the winter. Large numbers of seabirds, particularly Arctic terns, which nest nearby, gather to catch herring, trout, salmon, krill and other fish. Breiðamerkursandur (the large sand deposits in the area) is the main habitat of the Arctic skua (Stercorarius parasiticus).

BirdLife International of Cambridge, England, stated that a survey of Chinese experts found that the number of crested terns fell to 50 birds, half the population of 2004. A Chinese survey team led by Chen Shuihua stated that the bird was "on the verge of extinction."Chinese seabird on verge of extinction It is currently threatened by illegal egg collection, typhoons, and disturbance of nesting colonies by fishermen. There is also a threat of hybridization with the greater crested tern.

It is the site of the 67 km2 Cape Portland Important Bird Area which includes the cape itself, some adjacent land, a strip of coastline east of the cape extending to Policemans Point at the mouth of Ansons Bay, and nearby Swan Island. This area supports more than 1% of the world population of the Cape Barren goose, chestnut teal and the near threatened hooded plover. It also occasionally supports large numbers of pied oystercatchers, double-banded plovers and breeding fairy terns.

High aspect ratio wings, which usually have low wing loading and are far longer than they are wide, are used for slower flight. This may take the form of almost hovering (as used by kestrels, terns and nightjars) or in soaring and gliding flight, particularly the dynamic soaring used by seabirds, which takes advantage of wind speed variation at different altitudes (wind shear) above ocean waves to provide lift. Low speed flight is also important for birds that plunge-dive for fish.

The coastal strand habitat lies between the Pacific Ocean and the upper edge of the beach or coastal marsh. Species enjoying this niche are the California sea lion, harbor seal, Snowy egret, Great blue heron, cormorant and a variety of terns, murres, gulls and other shorebirds. Within the tidepool area there are also sea urchins, anemone, hermit crabs and numerous other mollusks. The flanks of San Vicente Creek and another unnamed drainage further south in the preserve are coastal salt marsh habitat.

Where numerous large animals are present, cattle egrets selectively forage around species that move at around 5–15 steps per minute, avoiding faster and slower moving herds; in Africa, cattle egrets selectively forage behind plains zebras, waterbuck, blue wildebeest and Cape buffalo. Dominant birds feed nearest to the host, and obtain more food. The cattle egret may also show versatility in its diet. On islands with seabird colonies, it will prey on the eggs and chicks of terns and other seabirds.

In protected areas, plant life includes beard-heath, bower spinach, coast daisy bush, daisies and cushion bush. The wilder terrain hosts an assortment of she- oaks, dogwoods, correa, messmate, trailing guinea-flower, woolly tea-tree and scented paperbark. The fauna in the park is largely ornithological; and includes honeyeaters, southern emu and fairy wrens, swamp harriers, rufous bristlebird, peregrine falcons, pelicans, ducks, black swans and egrets. Penguins, terns and dotterels are located along the shoreline, with hooded plovers nesting in exposed locations.

There are no significant differences between the sexes. In non-breeding adults the forehead and underparts become white, the bill is all black or black with a red base, and the legs are dark red or black. The upperwings have an obvious dark area at the front edge of the wing, the carpal bar. Terns that have not bred successfully may start moulting into non-breeding adult plumage from June, but late July is more typical, with the moult suspended during migration.

Immature Adult and immature The Indian river tern or just river tern (Sterna aurantia) is a tern in the family Laridae. It is a resident breeder along inland rivers from Iran east into the Indian Subcontinent and further to Myanmar to Thailand, where it is uncommon. Unlike most Sterna terns, it is almost exclusively found on freshwater, rarely venturing even to tidal creeks. This species breeds from March to May in colonies in less accessible areas such as sandbanks in rivers.

Collaboration with landowners on species management is therefore important, as is community education to encourage this. Feral cats are thought to be the most significant predator on the island, with domestic cats and dogs also known to kill wildlife. Hooded plovers and terns that nest along Cloudy Bay’s beaches are particularly vulnerable to predation by cats. Approximately 80% of the feral cats on Bruny Island carry toxoplasmosis (a parasite which infects and kills many animals when bitten), of which marsupials are particularly susceptible.

Motu Nui is the summit of a large volcanic mountain which rises over 2,000 meters from the sea bed. It measures 3.9 hectares in land area and is the largest of the five satellite islets of Easter island. The ritual of the "Bird Man" cult was a competition to collect the first egg of the manutara. This took place starting from Motu Nui where the Hopu (representatives from each clan) waited for the sooty terns to lay their first eggs of the season.

Hamford Water is a biological Site of Special Scientific Interest between Walton-on-the-Naze and Harwich in Essex. The site is a tidal inlet which has marsh grasslands, creeks, mud and sand flats, salt marshes, islands and beaches. It is described by Natural England as "of international importance for breeding little terns and wintering dark-bellied brent geese, wildfowl and waders, and of national importance for many other bird species." Rare plants include hog's fennel and slender hare's-ear.

The Hoher Knechtsand measures in an east-west direction and is between wide in the west and wide in the east. The area of the sandbank above the high water mark is about . The Großer Knechtsand, together with the island of Trischen, is one of the most important moulting areas for the shelduck, and, with Trischen, Norderoog and Minsener Oog, has one of the largest and longest-lasting colonies of Sandwich terns. Eider duck and common seal also occur here in large numbers.

The spill cleanup occurred during the nesting season for snowy plovers so special precautions were necessary while cleaning up tar balls. The birds are often found on the beaches along the coast of the Oxnard plain. Their nests are hard to see in the open sand and the birds are easily frightened away by human activity leaving the eggs to fast-moving predators such as sea gulls. Least terns were another endangered species of bird that was a concern during the cleanup efforts.

Nesocichla eremita, the Tristan thrush. Tristan is primarily known for its wildlife. The island has been identified as an Important Bird Area by BirdLife International because there are 13 known species of breeding seabirds on the island and two species of resident land birds. The seabirds include northern rockhopper penguins, Atlantic yellow-nosed albatrosses, sooty albatrosses, Atlantic petrels, great-winged petrels, soft-plumaged petrels, broad-billed prions, grey petrels, great shearwaters, sooty shearwaters, Tristan skuas, Antarctic terns and brown noddies.

Broadcast 10 October 1990, this programme describes the ways that various species care for their young. Attenborough defines childhood as achieving two tasks: growing and surviving. He highlights the elephant seal as an animal that experiences a compressed childhood, being abandoned after three weeks and left for up to another eight alone, while it becomes large enough to be able to swim. For terns, there is safety in numbers as the dense population works together to drive out marauding gulls.

Over 110 species of birds have been spotted in the lake. The spot-billed pelican, painted stork, openbill stork, ibis, Indian spot-billed duck, teal and black- winged stilt visit the lake during their migration. Various families of birds recorded include cormorants, herons, storks, ibis, kites, ducks, francolin, crakes, jacanas, plovers, sandpipers, terns, doves and pigeons, parakeet, cuckoos, owls, swifts, kingfishers, bee-eaters, rollers, barbets, woodpeckers, larks, swallows, wagtails, shrikes, bulbul, robin, babblers, warblers, flycatchers, flowerpecker, sunbirds, munias, sparrows, weavers, myna, orioles, drongos and crows.

In the case of Iceland's Jökulsárlón glacial lagoon located on the edge of the Atlantic Ocean, tides bring in an array of fish species to the edge of the glacier. These fish attract an abundance of predators from birds to marine mammals, that are searching for food. These predators include fauna such as, seals, arctic terns and arctic skua. Glacial lakes that have been formed for a long period of time have a more diverse ecosystem of fauna originating form neighboring tributaries or other glacial refugia.

The emergency shoulders on the bridge structure were occupied by concrete sidewalks. The original railway bridge immediately downstream of the new highway bridge was dismantled and the iron structure was scrapped, although the stone piers were left in place. These became a nesting site for cormorants and terns for the next three decades (1960s to 1990s). Ice and wind and wave damage by the turn of the 21st century had caused the majority of the old piers to collapse and are now mostly invisible from the bridge.
|

Also present are three species of otter, one of which, the smooth-coated otter (Lutrogale perspicillata), has been domesticated by local fishermen. The South Asian river dolphin (Platanista gangetica) inhabits some of the larger water channels. Birds are plentiful with over 270 having been recorded in the area including 38 species of raptor, 95 species of waterfowl and 9 of kingfisher. On the coast there are gulls and terns, on the mudbanks waders are plentiful and various forest birds are found among the trees.

Lighthouse keepers who used to live on the island introduced rabbits as living a food reserve. As a major breeding site for seabirds, the island was placed under protection in 1959. Breeding birds in 2004 were the herring gull, lesser black-backed gull, common gull, common tern, Arctic tern, Sandwich tern and little tern, as well as the magpie, carrion crow and swallow. While the numbers of terns amount to more than 2,000 pairs, only a few pairs of the little tern were noted.

Their lower mandible skims or slices over the water's surface, ready to snap shut any small fish unable to dart clear. The skimmers are sometimes included within the gull family Laridae but separated in other treatments which consider them as a sister group of the terns. The black skimmer has an additional adaptation and is the only species of bird known to have slit-shaped pupils. Their bills fall within their field of binocular vision, which enables them to carefully position their bill and capture prey.

|
Marshes provide a habitat for marine oriented species including terns, gulls, sandpipers ), loons and ibis. In developing the island, care has been taken to preserve as much of the natural habitat as possible. The Architectural Review Committee (ARC) has strict guidelines for the development and maintenance of landscape plans consistent with the long-term preservation of the island's natural environment. In addition, a land management plan provides guidelines and standards for the maintenance of the island's common properties and open spaces, including the golf course.

The black noddy and the white tern nest above ground level on cliffs or in trees. Migratory terns move to the coast after breeding, and most species winter near land, although some marine species, like the Aleutian tern, may wander far from land. The sooty tern is entirely oceanic when not breeding, and healthy young birds are not seen on land for up to five years after fledging until they return to breed. They lack waterproof plumage, so they cannot rest on the sea.
|
|
Terns normally breed in colonies, and are site- faithful if their habitat is sufficiently stable. A few species nest in small or dispersed groups, but most breed in colonies of up to a few hundred pairs, often alongside other seabirds such as gulls or skimmers. Large tern species tend to form larger colonies, which in the case of the sooty tern can contain up to two million pairs. Large species nest very close together and sit tightly, making it difficult for aerial predators to land among them.
|
|
The roseate tern is trapped for food on its wintering grounds. Terns and their eggs have long been eaten by humans and island colonies were raided by sailors on long voyages since the eggs or large chicks were an easily obtained source of protein. Eggs are still illegally harvested in southern Europe, and adults of wintering birds are taken as food in West Africa and South America. The roseate tern is significantly affected by this hunting, with adult survival 10% lower than would otherwise be expected.

Larger reptiles and amphibians predate on smaller species, as will larger invertebrates such as centipedes and spiders. Birds such as owls, terns, rails and kingfishers will predate on geckos, as will blackbirds and magpies. Introduced predatory invertebrates such as ants, wasps and mantids have been known to predate some New Zealand lizard species. Brushtail possum Mites are common parasites of all lizard species in New Zealand, in the form of tiny red, orange or creamy white spots around the eyes, ears, armpits hind limbs and cloaca.

Many fish live in and also migrate along the Humber when returning from the sea to their spawning grounds in Yorkshire, Lincolnshire and Derbyshire. Salmon, sole, cod, eel, flounder, plaice, sprat, lamprey and sand goby have all been caught within the estuary. The Humber is also a good place for over-wintering birds and is a good breeding ground for bitterns, marsh harriers, little terns and avocets. It forms part of the Severn-Trent flyway, a route used by migratory birds to cross Great Britain.

|
Birds such as loons, grebes, ducks, kingfishers, and bald eagles are known to live around streams and other regions of the watershed. Auks, gulls, and terns have been spotted around the river's mouth, and black-legged kittiwakes nest in the area during the winter. The wildlife in the Kalmiopsis region of the Chetco watershed is more diverse than that of any other region in Oregon. Mammals such as American black bears, black-tailed deer, bobcats, ring-tailed cats, and gray foxes are common inhabitants of this region.

A great kiskadee (right) mobbing a hawk Birds that breed in colonies such as gulls are widely seen to attack intruders, including encroaching humans. In North America, the birds that most frequently engage in mobbing include mockingbirds, crows and jays, chickadees, terns, and blackbirds. Behavior includes flying about the intruder, dive bombing, loud squawking and defecating on the predator. Mobbing can also be used to obtain food, by driving larger birds and mammals away from a food source, or by harassing a bird with food.

A 3 ha site consisting of a sandspit, within the 4 ha Raspins Beach Conservation Area on the northern side of the river mouth, has been identified by BirdLife International as an Important Bird Area (IBA) because it regularly supports 15-25 breeding pairs of vulnerable fairy terns. It also supports breeding populations of red-capped (10 pairs) and hooded plovers (5-6 pairs), and pied oystercatchers (5-7 pairs). Flocks of up to 50 red-necked stints are present in summer.BirdLife International. (2011).

Whiskered tern During autumn, parts of the Nile River are red with lotus flowers. The Lower Nile (North) and the Upper Nile (South) have plants that grow in abundance. The Upper Nile plant is the Egyptian lotus, and the Lower Nile plant is the Papyrus Sedge (Cyperus papyrus), although it is not nearly as plentiful as it once was, and is becoming quite rare. Several hundred thousand water birds winter in the delta, including the world's largest concentrations of little gulls and whiskered terns.

The Stewart B. McKinney National Wildlife Refuge is a National Wildlife Refuge in ten units across the U.S. state of Connecticut. Located in the Atlantic Flyway, the refuge spans of Connecticut coastline and provides important resting, feeding, and nesting habitat for many species of wading birds, shorebirds, songbirds and terns, including the endangered roseate tern. Adjacent waters serve as wintering habitat for brant, scoters, American black duck, and other waterfowl. Overall, the refuge encompasses over of barrier beach, intertidal wetland and fragile island habitats.

The park is home to badgers and foxes and to ten species of butterfly identified among the local wildlife. The estuary along which the park is located is home to populations of ragworm, lugworm, and cockles which support various species of bird wildlife in the area, including common redshanks, common shelducks, northern lapwings, skylarks, meadow pipits and terns. During high spring tides visitors may also catch a glimpse of certain birds of prey such as peregrines, hen harriers and the daytime hunting short-eared owls.

It is thought that they could not have swum the five-kilometre stretch of open sea from the Kapiti Coast. Kapiti Island is one of Wellington region's “coastal habitats of significance for indigenous birds”. It provides predator free nesting habitat to little blue penguins, red-billed gulls, white-fronted terns and the reef heron. A further four Nationally Threatened or At Risk species occur on the coast of Kapiti Island including the Black shag, the Caspian tern, the pied shag and the variable oystercatcher.

About 340 species of bird have been recorded in Bahrain, the majority being migrants on their way southwards in autumn and northwards in spring. There are a range of habitats to which they are attracted including cultivated areas, open countryside, marshes, mudflats and mangrove swamps. Visiting wetland birds include sandpipers, curlews and plovers, and the mangrove areas are favoured by egrets, herons, flamingoes, terns and gulls. By contrast, the Hawar Islands have fewer habitat types and only about 60 migratory species have been recorded here.

The royal tern has few predators when it is mature, but before the chicks hatch or while they are chicks the tern is threatened by humans, other animals, and the tides. Humans threaten terns by fishing and by disrupting the tern nesting sites. Fishing nets can catch a tern while it is diving, making it unable to feed or it may cause it to drown if it is caught under water. Animals such as foxes, raccoon, and large gulls prey on tern chicks and tern eggs.

It is accessed by a roadway that winds down to fajã, to a platform with limited parking. From this point the homes and coastal area reachable by foot or by small single-engine vehicles. The port is used for small-scale fishing, from along the coast and in the channel, which includes the capture of Gadiformes such as Atlantic horse mackerel. The more frequent migratory and marine birds in the fajã include: sea-gulls, terns, shearwaters, kites, blackbirds and even wild ducks, as well as occasionally sandpipers.

Though most of Ormond-by-the-Sea is little more than a half-mile wide, it supports no fewer than six distinct ecological zones. The beach, or tidal zone, features distinctive reddish-colored sand created by crushed coquina shells. Here may be found sand fleas and ghost crabs, as well as a variety of coastal birds including plovers, stilts, avocets, terns, and gulls. Just above the tide line, several species of sea turtles are known to lay their eggs, including the leatherback, Atlantic loggerhead, and green turtle.

Loon 61:160-162. Similarly, as mainly recorded in New England, attempts to reintroduce ospreys, after they were also hit hard by DDT, were affected by heavy owl predation on nestlings, and the owls were also recorded to take a large toll locally on the threatened colonies of roseate terns. Where clear- cutting occurs in old-growth areas of the Pacific Northwest, spotted owls have been badly affected by considerable great horned owl predation.Forsman, E. D., E. C. Meslow, and H. M. Wight. 1984.

Anous is a genus of seabirds in family Laridae which also contains the gulls, terns and skimmers. The genus contains five species. The noddies inhabit tropical oceans and have a worldwide distribution, ranging from Hawaii to the Tuamotu Archipelago and Australia in the Pacific Ocean, from the Red Sea to the Seychelles and Australia in the Indian Ocean and in the Caribbean to Tristan da Cunha in the Atlantic Ocean. They nest in colonies on cliffs or in short trees or shrubs, seldom on the ground.

The backwaters have a unique ecosystem: freshwater from the rivers meets the seawater from the Arabian Sea. A barrage has been built near Thanneermukkom, so salt water from the sea is prevented from entering the deep inside, keeping the fresh water intact. Such fresh water is extensively used for irrigation purposes. Many unique species of aquatic life including crabs, frogs and mudskippers, water birds such as terns, kingfishers, darters and cormorants, and animals such as otters and turtles live in and alongside the backwaters.

A significant population of long-tailed ducks winter off Nantucket. Small offshore islands and beaches are home to roseate terns and are important breeding areas for the locally threatened piping plover. Protected areas such as the Monomoy National Wildlife Refuge provide critical breeding habitat for shorebirds and a variety of marine wildlife including a large population of grey seals. Since 2009, there has been a significant increase in the number of Great white sharks spotted and tagged in the coastal waters off of Cape Cod.

As many as 18,000 dolphins, behaving like sheepdogs, round the sardines into these bait balls, or herd them to shallow water (corralling) where they are easier to catch. Once rounded up, the dolphins and other predators take turns plowing through the bait balls, gorging on the fish as they sweep through. Seabirds also attack them from above, flocks of gannets, cormorants, terns and gulls. Some of these seabirds plummet from heights of , plunging through the water leaving vapour-like trails behind like fighter planes.

Up to three eggs may be laid, their dull colours and blotchy patterns providing camouflage on the open beach. Incubation is by both sexes, and the eggs hatch in around 21–22 days, longer if the colony is disturbed by predators. The downy chicks fledge in 22–28 days. Like most terns, this species feeds by plunge-diving for fish, either in the sea or in freshwater, but molluscs, crustaceans and other invertebrate prey may form a significant part of the diet in some areas.
|
|
It lays from one to three eggs per clutch, most often two. It is one of the most aggressive terns, fiercely defensive of its nest and young. It will attack humans and large predators, usually striking the top or back of the head. Although it is too small to cause serious injury to an animal of a human's size, it is still capable of drawing blood, and is capable of repelling many raptorial birds, polar bears and smaller mammalian predators such as foxes and cats.

Caroline Island is an important breeding site for a number of species of seabirds, most notably the sooty tern (Onychoprion fuscata), numbering around 500,000 - a colony of sooty terns dominates the eastern islets - and the great frigatebird (Fregata minor), numbering over 10,000. Caroline Island and its neighbor, Flint Island, also host some of the world's largest populations of the coconut crab. (Birgus latro). Other native animals include the Tridacna clam, which is abundant in the central lagoon, hermit crabs, and multiple species of lizards.

The aviary, which cost £7 million to build, was at its highest point and had a total volume of . This free flying enclosure was home to mammals and birds including South American fur seals, African penguins, macaroni penguins, sea ducks, pied avocet, redshanks, black-necked stilts, ruffs, and terns. The aviary was the first open-air auk exhibit in the world, and won a design award. It was also the first place in the U.K to breed pigeon guillemots, common guillemots and tufted puffins.

She preferred to use the term "muse" rather than "subject." She would also try to interact with her "muses" on equal terns. If she was photographing a nude woman, she would ask if the women wanted her to be nude as well. In an effort to ensure that affirming images and positive self-expression occurred outside of what she considered traditional patriarchal venues, Biren included her work in off our backs, The Washington Blade, Gay Community News, and on many LP album and book covers.

They eat mainly fish, birds, eggs, carrion, offal, rodents, rabbits, and occasionally berries. Great skua attacking northern gannet near Stac an Armin (St Kilda, Scotland)They will often obtain fish by robbing gulls, terns and even northern gannets of their catches. They will also directly attack and kill other seabirds, up to the size of Herring Gulls. Like most other skua species, it continues this piratical behaviour throughout the year, showing less agility and more brute force than the smaller skuas when it harasses its victims.

Field observations and laboratory experiments suggest that ribbed bog moss has broad tolerance and may be relatively insensitive to macronutrient concentrations. On the Svalbard archipelago in Norway, ribbed bog moss grows on small "bird islands" where eiders, Arctic terns, and other migratory birds nest offshore of the main island, Spitsbergen. Nitrogen levels on the bird islands are very high. On Spitsbergen Island, however, ribbed bog moss grows on dry hummocks and moist hummock edges, both of which have low nitrogen levels but probably provide moisture levels that favor ribbed bog moss.

The coastal wetlands at Zones Humides du Littoral du Togo are used by waders and terns migrating along the west coast of Africa. The common house martin overwinters in the north of the country and the common swift, the Alpine swift and the mottled swift all pass through on their migrations. The greatest diversity of forest birds occurs in the southwest, near the border with Ghana. The four Important Bird Areas are the Oti Valley Faunal Reserve, the Kéran National Park, the Fazao Malfakassa National Park and the Misahöhe Forest Reserve.

Location of Ducie Atoll within Pitcairn Islands Ducie Island is an uninhabited atoll in the Pitcairn Islands. It lies east of Pitcairn Island, and east of Henderson Island, The island is composed of four islets: Acadia, Pandora, Westward and Edwards. Despite its sparse vegetation, the atoll is known as the breeding ground of a number of bird species. More than 90% of the world population of Murphy's petrel nests on Ducie, while pairs of red-tailed tropicbirds and fairy terns make around 1% of the world population for each species.

Wardang island is home to various seabirds, including silver gulls, terns, oystercatchers (once referred to as "redbills"), little penguins and cormorants. The bird life is acknowledged in the European names given to various geographical features of the island, including Pidgeon Rock and Pidgeon Island to the north and Bird Point and Swan Bay to the northeast. Snapper Point is another geographical feature named after local fauna; in this instance after a fish caught in adjacent waters. Another fish caught off Wardang Island is the Australian herring (known locally as Tommy Ruff).

It is of international importance for wintering brent geese and black-tailed godwits, and of national importance for six other bird species, including little terns. It also has important assemblages of invertebrates and plants, such as golden samphire and shrubby seablite. A peat seam in St Osyph Marsh has been dated to 4280 BP, and this marsh is important for saltmarsh morphology. There are important geological exposures for Pleistocene studies at East Mersea; investigation is at an early stage, but they show warm climate deposits from one or more post-Anglian interglacials.

In 1985, the island became part of the Stewart B. McKinney National Wildlife Refuge after it was acquired from the U.S. Coast Guard. According to the Connecticut Audubon Society, "it currently supports over 95% of the nesting Common Terns in Connecticut. It is the site of one of the ten largest Roseate Tern (~45 pairs) colonies in Northeastern North America, and is the only regular nesting location for this federally endangered species in the state." Also living on the island is the American oystercatcher, with one to two breeding pairs noted each year.
|

Several of the site’s 24 islets provide undisturbed sandy beach habitat for nesting green turtles, as well as forest and shrubland supporting breeding populations of terns and other seabirds. Its coral reefs support a distinct community of marine benthic plants and animals, a diverse decapod crustacean and hydroid fauna, and feeding habitat for migratory shorebirds and seabirds. Seaweed communities are also important. There are no known native terrestrial mammals within the Reserves; introduced black rats were present on South West Coringa Islet for many years, but were eliminated by 1991 after an eradication program.

Terns are long- lived birds and are relatively free from natural predators and parasites; most species are declining in numbers due directly or indirectly to human activities, including habitat loss, pollution, disturbance, and predation by introduced mammals. The Chinese crested tern is in a critical situation and three other species are classed as endangered. International agreements provide a measure of protection, but adults and eggs of some species are still used for food in the tropics. The eggs of two species are eaten in the West Indies because they are believed to have aphrodisiac properties.
|
|
Most species have little or no nest, laying the eggs onto bare ground, but Trudeau's tern, Forster's tern and the marsh terns construct floating nests from the vegetation in their wetland habitats. Black and lesser noddies build nests of twigs, feathers and excreta on tree branches, and brown, blue, and grey noddies make rough platforms of grass and seaweed on cliff ledges, in cavities or on other rocky surfaces.Watling (2003) pp. 206–207. The Inca tern nests in crevices, caves and disused burrows, such as that of a Humboldt penguin.
|
|
In the West Indies, the eggs of roseate and sooty terns are believed to be aphrodisiacs, and are disproportionately targeted by egg collectors. Tern skins and feathers have long been used for making items of clothing such as capes and hats, and this became a large-scale activity in the second half of the nineteenth century when it became fashionable to use feathers in hatmaking. This trend started in Europe but soon spread to the Americas and Australia. White was the preferred colour, and sometimes wings or entire birds were used.

New Zealand is a major sponsor of conservation efforts on Kiritimati. Egg collecting for food on a massive scale was frequent in the past but is now outlawed. It is to be noted that the sooty terns for example could sustain occasional collection of effectively all of a season's eggs (over 10 million), if given sufficient time to recover and if cats are absent. Even egg collecting on a scale that significantly decreases costly food imports thus in theory could be possible, but not until the cat and rat populations have been brought under control.

The island has been identified as an Important Bird Area (IBA) by BirdLife International as a breeding site for seabirds, of which there are at least 26 breeding species. Birds nesting in relatively large numbers include king, northern rockhopper and macaroni penguins, wandering, sooty and light-mantled albatrosses, northern giant petrels, medium-billed prions, Kerguelen and soft-plumaged petrels, and South Georgia diving petrels. Other island breeders in smaller numbers are southern giant petrels, grey-headed albatrosses and Kerguelen terns. Crozet blue-eyed shags, black-faced sheathbills and Eaton's pintails are resident.

Around 1800, Griend still had an area of 0.25 km2, but the island was moving to the southeast at a speed of 7 metres a year. By that time, all of its inhabitants had abandoned the island, and from then on it was used by inhabitants of Terschelling as a grazing area for sheep, and for the making of hay. The eggs of gulls and terns were also gathered there for consumption. In 1916, the grazing rights on the island were bought by the Vereniging Natuurmonumenten, Griend, Vereniging Natuurmonumenten.

Birds of prey that are present in the state are great horned owls, bald eagles, red-tailed hawks, American kestrels, and northern harriers. Waterfowl like mallards, wood ducks, canvasbacks, American black ducks, Canada geese, and blue-winged teals can be found in the region. Maritime or shore birds of New York are great blue heron, killdeers, northern cardinals, American herring gulls, and common terns. Reptiles species that can be seen in land areas of New York are queen snake, massasauga, hellbender, diamondback terrapin, spotted turtle, and Blanding's turtle.

In the years before the refuge's founding, multiple expeditions were made to the islands. Ornithologist Henry L. Ward, then-curator of the Milwaukee Public Museum, visited the area numerous times to study the herring gull populations. While visiting Gravel Island in 1906 and 1907, Ward noted very large colonies of herring gulls as well as Caspian terns while observing their behavior and collecting specimens from the island. In 1913, the refuge was formed by executive order from Gravel Island and Spider Island to protect the breeding grounds of birds living there.

The dock basin is home to a variety of bird wildlife with ducks, coots and cormorants in residence. Swans and various gulls spend time on the dock and herons may be seen feeding nearby in the river. In 2010 members of the Fylde Bird Club installed a number of gravel-filled tyres and slate shelters on the pontoons at the Preston Marina to attract common terns and entice them to breed. The project proved to a success and was followed by the club and local schools building over 170 breeding boxes to attract more birds.
|
|
In 2000, 7.5% of the population of this subspecies bred on roofs. Artificial islands in salt pans and sewage works have also recently been colonised by this adaptable seabird. Adult terns have few predators, but in Namibia immature birds are often robbed of their food by kelp gulls, and that species, along with Hartlaub's gull, silver gull and sacred ibis, has been observed feeding on eggs or nestlings, especially when colonies are disturbed. Smaller subcolonies with a relatively larger numbers of nests located on the perimeter are subject to more predation.

The southern shore is in the Republic of Ireland. At the mouth of the lough are several small rock and shingle islands which are of importance to terns. The Ramsar Site lies between Killowen Point and Soldiers Point on the northern shores of Carlingford Lough and the landward boundary coincides entirely with that of the Carlingford Lough Area of Special Scientific Interest and the Carlingford Lough Special Protection Area. The site qualified under Criterion 2 of the Ramsar Convention because it supports important groups of vulnerable and endangered Irish Red Data Book bird species.

Cooper's hawk Similarly, in Cooper's hawks, female desertion of offspring has been found to be closely related to both the likelihood of offspring survival and future reproductive success. Females in weak physical condition are more likely to abandon offspring to complete migration, increasing breeding chances and opportunities for the following year. In Whiskered terns, the majority of deserters are female and is related to provisioning rate: females providing more food were less likely to desert. In mammals, aardwolves have been shown to practice male mate desertion in response to female promiscuity.

In modern times, Craney Island is an industrial area and has been used as a location for placement of dredged materials since 1957. It is operated by the U.S. Army Corps of Engineers. A major fueling depot for the United States Navy is located adjacent. The Norfolk District of the Corps staff has received recognition for the creation, protection, and preservation of a critical habitat for birds such as the piping plover, least terns, brown pelicans, osprey, and other threatened or endangered species that use the island as a large nesting ground.

The island is one of two known active breeding colonies of elegant tern in Mexico. During two years, a large number of nests were destroyed by tidal flooding, but there were only low levels of nests lost to predation. The birds nesting on Montague Island have reacted strongly to El Niño, with brown boobies being replaced by blue-footed boobies, and an increase in nesting of least, elegant, and royal terns, as well as black skimmers. Montague Island is one of the few locations where Mulinia coloradoensis, an endangered species of clam, is found.

Commonly sighted land and amphibious animals include white-tailed deer, marsh rabbits, raccoons, minks, alligators, armadillos, terrapins and frogs. Overhead, along the shore and in the marshes, an extensive variety of both native and migratory shorebirds can be seen year- round. Species include sandpipers, plovers, terns, gulls, herons, egrets, hawks, ospreys, cormorants, white ibis, brown pelicans, and the southern bald eagle. The area surrounding St. Simons Island and the Altamaha River delta is an important stopover for migrating shorebirds traveling between South America and their spawning grounds in the Canadian arctic.

These include flamingos, terns, pied avocets, Eurasion wigeons, and common chaffinches. Within the town are gardens and open spaces, among which are the Manuel Bivar Garden, Alameda João de Deus Garden, and the Mata do Liceu. The variety of species and natural conditions result in the region being a popular ecotourism zone, promoting birdwatching, boating trips into the delta, kayaking along the Ria Formosa, pedestrian trails, and biking tours, accompanied by nature guides. The municipality is crossed by the southern Ecovia do Algarve, a bicycling circuit that connects the Algarve to the rest of Europe.

Mill End Farm, which has been run by the Bowden family since at least 1965, is opposite the lock and has farmed most of the land in and around the southern Hambleden area. This part of the Thames is characterised by willow trees and a large biodiversity of wildlife including swans, grebes, ducks, herons, terns and kingfishers. The footpath next to Hambleden Lock, the public towpath, provides a significant amenity to Mill End. Anne Petrie, daughter of the famous Egyptian archaeologist Flinders Petrie lived in Mill End; she is buried in Hambleden church-yard.

Red Island, Mill Hill, Hillside, the nearby Ardgillan Park and Demesne, Barnageeragh and to a lesser extent Baldungan Castle, provide vantages overlooking the town. Rockabill has the largest numbers of breeding roseate terns in Europe. It is also the farthest set of islands from the town and has a lighthouse which is exactly 4 miles from the nearest path on the mainland at Red Island. The Martello tower on Shenick Island is one of a number of defensive towers erected during the Napoleonic era along the Irish coast by the British.

There is a range of threatened and endemic species on the Tiwi Islands. Thirty-eight threatened species have been recorded, and a number of plants and invertebrates are found nowhere else, including eight plant species and some land snails and dragonflies. Threatened mammals include Brush-tailed rabbit rats, northern brush-tailed phascogales, false water rats and Carpentarian dunnarts. The islands host the world's largest breeding colony of crested terns and a large population of the vulnerable olive ridley turtle; a sea turtle conservation program commenced on the islands in 2007.

Loch an Duin is a complex system of freshwater, brackish and sea lochs, tidal channels and islands, on and close to North Uist off the west coast of Scotland. An area of 2,621 hectares has been protected since 1990 as a Ramsar Site. The area under protection includes part of the north-eastern coastland of North Uist, as well as nearby islands and skerries in the Sound of Harris. It supports nationally important populations of common terns, around 1.5% of the UK breeding population, as well as providing habitat for otters.

Falkner Island Light is the second oldest extant lighthouse in Connecticut and was listed on the National Register of Historic Places on May 29, 1990. The Town of Guilford proclaimed that September 7, 2002, would be "Faulkner's Island Light Day" to honor the 200th birthday of the lighthouse. Falkner Island Light is home to one of the world's largest breeding colonies of the endangered roseate tern; the nesting season is May through August. Access to Falkner Island and the light is restricted during the nesting season of the roseate terns.

Sea and desert birds have been found to have a salt gland near the nostrils which concentrates brine, later to be "sneezed" out to the sea, in effect allowing these birds to drink seawater without the need to find freshwater resources. It also enables the seabirds to remove the excess salt entering the body when eating, swimming or diving in the sea for food. The kidney cannot remove these quantities and concentrations of salt. The salt secreting gland has been found in seabirds like pelicans, petrels, albatrosses, gulls, and terns.

This bat species was added to New Jersey's endangered and threatened species list in 2012. White-Nose Syndrome Research Because of the decrease in bat populations caused by white nose syndrome, the US Fish and Wildlife Service and many states including New Jersey, have been studying bat colonies during the summer and winter months. They studying and learning about causes and consequences of the disease. Beach Nesting Bird Project CWF assists with the recovery of beach nesting bird species including piping plovers, least terns, black skimmers, American oystercatchers and red knotss.

Like all Thalasseus terns, the West African crested tern feeds by plunge-diving for fish, usually from saline environments. It usually dives directly, and not from the "stepped-hover" favoured by Arctic tern. The offering of fish by the male to the female is part of the courtship display. It was suspected by wildlife conservationists in The Gambia that the West African birds were a separate species and analysis of DNA by scientists at the University of Aberdeen and the University of Montpellier have confirmed that the West African albididorsalis is a separate species.

Toward the western end of the boardwalk, several portions of the beach are fenced off to preserve the nesting habitat for several species of terns and plovers, making for a unique urban birdwatching locale. After 2010, there was a major resurgence in the Rockaways' popularity. Various media began reporting on artists such as Andrew VanWyngarden, co-founder of popular psychedelic rock band MGMT, purchasing homes on the beach. The peninsula was dubbed "Williamsburg on the Rockaways", because some surfers from there began to spend whole summers out in the Rockaways.

The Arctic tern migrates the longest distance of any bird. Seabird migration is similar in pattern to those of the waders and waterfowl. Some, such as the black guillemot Cepphus grylle and some gulls, are quite sedentary; others, such as most terns and auks breeding in the temperate northern hemisphere, move varying distances south in the northern winter. The Arctic tern Sterna paradisaea has the longest-distance migration of any bird, and sees more daylight than any other, moving from its Arctic breeding grounds to the Antarctic non-breeding areas.

Further decline came in the 1940s due to the widespread use of the pesticide DDT. At that time, they were placed on both the Alabama and federal endangered species list. Partly due to increased nesting and propagation of the brown pelicans on Gaillard Island, the brown pelican was removed from the state's endangered species list in 1995, and in 2009, the brown pelican was removed from the federal endangered species list. Today Gaillard Island is an important habitat for thousands of birds representing species of skimmers, stilts, terns, pelicans, egrets, herons, and ibis.

Plants found on the island include several lichen and moss species as well as Antarctic Hairgrass. The island has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of about 100 pairs of south polar skuas. Other birds nesting on the island include chinstrap penguins (2000 pairs), Antarctic terns (125 pairs), kelp gulls (40 pairs), Wilson's and black-bellied storm petrels, Cape petrels, brown skuas, snowy sheathbills and imperial shags. Weddell and Antarctic fur seals regularly haul out on the beaches.

Eggs and young are vulnerable to predation by mammals such as rats and American mink, and large birds including gulls, owls and herons. Common terns may be infected by lice, parasitic worms, and mites, although blood parasites appear to be rare. Its large population and huge breeding range mean that this species is classed as being of least concern, although numbers in North America have declined sharply in recent decades. Despite international legislation protecting the common tern, in some areas populations are threatened by habitat loss, pollution or the disturbance of breeding colonies.

Hume (1993) pp. 120–123. left Like many terns, this species is very defensive of its nest and young, and will harass humans, dogs, muskrats and most diurnal birds, but unlike the more aggressive Arctic tern, it rarely hits the intruder, usually swerving off at the last moment. Adults can discriminate between individual humans, attacking familiar people more intensely than strangers. Nocturnal predators do not elicit similar attacks; colonies can be wiped out by rats, and adults desert the colony for up to eight hours when great horned owls are present.

In the winter the cap is greyish white, flecked and streaked with black, there is a dark mask through the eye, and the tip of the bill becomes dusky. The sexes are similar but juveniles have a brown head, brown- marked grey upperparts, grey breast sides and white underparts. The bill is yellowish with a dark tip As with other Sterna terns, the river tern feeds by plunge-diving for fish, crustaceans, tadpoles and aquatic insects in rivers, lakes, and tanks. Its numbers are decreasing due to the pollution of their habitat.

The birds follow a somewhat convoluted course in order to take advantage of prevailing winds. The average Arctic tern lives about thirty years, and will, based on the above research, travel some 2.4 million km (1.5 million mi) during its lifetime, the equivalent of a roundtrip from Earth to the Moon over 3 times. A 2013 tracking study of half a dozen Arctic terns breeding in the Netherlands shows average annual migrations of c. . On their way south, these birds roughly followed the coastlines of Europe and Africa.

While the Arctic tern is similar to the common and roseate terns, its colouring, profile, and call are slightly different. Compared to the common tern, it has a longer tail and mono-coloured bill, while the main differences from the roseate are its slightly darker colour and longer wings. The Arctic tern's call is more nasal and rasping than that of the common, and is easily distinguishable from that of the roseate. This bird's closest relatives are a group of South Polar species, the South American (Sterna hirundinacea), Kerguelen (S.

The cape is an important breeding site for Antarctic fur seals The cape has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a large breeding colony of up to about 10,000 pairs of chinstrap penguins. Other birds nesting at the site in smaller numbers include gentoo penguins, kelp gulls, brown skuas, snowy sheathbills, Antarctic terns, imperial shags, Wilson's and black-bellied storm petrels, and Cape petrels. The site also contains the largest number of breeding Antarctic fur seals in the Antarctic Peninsula region.

"In Barnegat Bay and Little Egg Harbor, the rising sea is already eroding and submerging small marsh islands, which are important nesting areas that protect common terns, black skimmers, and oystercatchers from land-based predators." "Changing temperatures could also disrupt ecosystems. For example, if water temperatures exceed during summer, eelgrass could be lost, which would remove a key source of food for many fish." Higher acidity in the water also threatens certain species, like scallops and surf clams; this could lower their populations, threatening New Jersey's commercial fishing industry.

The conservation park is an important area for Cape Barren geese The full extent of the conservation park is overlapped by an Important Bird Area (IBA) known as the Lake Newland Important Bird Area. The IBA which is a non-statutory arrangement has been identified by BirdLife International because it regularly supports over 1% of the world population of Cape Barren geese, as dry-season visitors from their offshore island breeding grounds, and significant numbers of fairy terns and hooded plovers. Slender-billed thornbills also occur in the park.

Map of Anguilla The lagoon is an important breeding site for least terns Long Pond, also known as Long Salt Pond, is a 23 ha brackish lagoon on the central south-eastern coast of the main island of Anguilla, a British Overseas Territory in the Caribbean. About 1.2 km long, it is separated from the sea at its eastern end by sand dunes. Its south shore is separated from the sea by a 300 m wide strip of scrub vegetation on limestone. The area to the north and west is residential.

The Damara tern eats mainly small fish, with the occasional squid, which are caught in repeated plunge dives from a height of 3-8m. Their migration is timed to coincide with spawning shoals of small fish in the shallow coastal waters of the Gulf of Guinea caused by strong upwellings of the coast of Ghana. These wintering birds roost communally but feed solitarily, spacing themselves at 10-50m from other Damara terns. Eggs are laid in a plain scrape in the substrate which is sometimes lined with shell chips or small stones.

The site has been identified by BirdLife International as an Important Bird Area (IBA) because it supports over 1% of the world populations of little penguins (with up to 26,000 birds), short-tailed shearwaters (up to 450,000 pairs) and Pacific gulls (with an estimated 52-490 birds). In the past it was occasionally visited by small numbers of orange-bellied parrots. One of the largest breeding colonies of crested terns in Victoria (2800 pairs) is at the Nobbies. Pied and sooty oystercatchers, as well as hooded plovers, use the beaches.

South-eastern Wexford is an important site for wild birds—the north side of Wexford Harbour, the North Slob, is home to 10,000 Greenland white-fronted geese each winter (roughly one third of the entire world's population), while in the summer Lady's Island Lake is an important breeding site for terns, especially the roseate tern. The grey heron is also seen. Throughout the county pheasant, woodpigeon and feral pigeons are widespread. Mute swan, mallard, kingfisher, and owls (the long-eared owl, the short-eared owl, and the barn owl) are less common - but plentiful.

The Wilderness Society described the area as a "marine superhighway", and whales and endangered flatback turtles observed in the area are at risk from the spill. By 3 September 2009, fishers observed sick and dying marine life, and an absence of birds in the spill area. The World Wildlife Fund (WWF) observed spinner dolphins, sooty terns, spotted sea snake and threatened hawksbill and flatback turtles swimming in the oil slick, and expressed concern about long- term effects. WWF also observed a wax-like residue from the oil spill.

Its food consists mainly of rodents, especially voles, but it will eat other small mammals such as mice, ground squirrels, shrews, rats, bats, muskrats and moles. It will also occasionally predate smaller birds, especially when near sea-coasts and adjacent wetlands at which time they attack shorebirds, terns and small gulls and seabirds with semi-regularity. Avian prey is more infrequently preyed on inland and centers on passerines such as larks, icterids, starlings, tyrant flycatchers and pipits. Insects supplement the diet and short-eared owls may prey on roaches, grasshoppers, beetles, katydids and caterpillars.

This is fired with water to make red brick, and the brickworks, which is still operational today, was built in 1845 to exploit this. Much wildlife is found on the Duddon Estuary, including 20% of the national natterjack toad population, who are attracted to the shallow breeding pools. The slagbanks around Askam are also very important as nesting sites for the rare Sandwich terns that live in the area. The beach is designated a Site of Special Scientific Interest (SSSI) because of the range of flora and fauna present on the sands.

The largest families are: Sylviidae (warblers) with 43 species, Turdidae (thrushes, chats) and Anatidae (swans, geese, ducks), both with 33 species and Accipitridae (eagles, vultures, hawks) with 32 species. The most populous genera are: Sylvia (warblers) with 15 species, Emberiza (buntings) with 14 and Larus (gulls) with 13, while Oenanthe (wheatears), Sterna (terns) and Falco (falcons) each comprise 11 species. The types of avifauna are not equally diffused over the whole area. The Palearctic species are found largely near the coast of the Mediterranean Sea and the highlands east and west of Jordan.

There is a fresh water artesian well that is 97 meters deep creating an oasis of date-producing palm trees where birds such as fulvous whistling duck, grey pelicans and American white pelicans live as well as grey herons, cranes and albatross. Other species of birds seen in the island are turnstones, spoonbills, skimmers, waders, and other shorebirds, gulls, terns, frigatebirds, and boobies. Along the island's fine sandy beach and the almost flat slopped ocean, in its large Tobari bay, tourists fish for mullets, sea bass, and two species of the genus Epinephelus.

Aquatic birds that nest in colonies are the most common vertebrate hosts, including gannets, terns and herons. Cygnet River and Wellfleet Bay viruses have been associated with an often-fatal disease in farmed and wild duck species, with symptoms including diarrhoea and lethargy. Most genus members tested can infect mice under laboratory conditions; they cause severe pathology and are frequently lethal. Quaranfil virus is the only member of the genus to have been shown to infect humans; infection generally appears to be asymptomatic and has occasionally been reported to be associated with mild fever.

Native birds like the threatened Newell's Shearwater were likely being restricted from breeding on Lehua Island due to predation by rats. Smaller, open-nesting seabirds such as terns and noddies were conspicuously absent from Lehua (save small numbers found in sea caves), also a suspected artifact of rat predation. Invasive rats ravage other threatened birds. Therefore, in August 2017, the DLNR Division of Forestry and Wildlife (DOFAW) with project implementation partner Island Conservation implemented an aerial application of bait with supplemental hand application to eradicate non-native invasive rats.

In the past, fish were farmed and harvested in the lake. Dhadimagi Kilhi is frequented by anglers who game for tilapia fish and visitors who enjoy boat riding and feeding the fish which inhabit the lake. Among the birds which inhabit the place apart from the common moorhen which is a bird exclusively found in Fuvahmulah only in the Maldivian archipelago, Maldivian white-breasted waterhen (Amaurornis phoenicurus maldivus) which is an endemic species of the Maldives too can be sighted by the lakeside. Among seasonal visitors are flamingos, herons and white terns.

The land adjacent to the point has been designated an Antarctic Specially Protected Area (ASPA 171) primarily to protect its ecological, scientific and aesthetic values from human interference. The size of the site is about 1 km2. It is geologically complex and rich in flora and fauna, with an extensive cover of mosses and lichens There are large colonies of chinstrap and gentoo penguins. Other birds recorded as breeding at the site in smaller numbers are brown and south polar skuas, kelp gulls, Antarctic terns, Wilson's storm petrels, southern giant petrels and snowy sheathbills.

While hunters armed only with bows and arrows would have had a difficult time hunting the swan, the introduction of firearms by European explorers would have made the swan a tempting target for hunters. By 1850, only small numbers of the swan remained in Eastern Canada, and the last sighting of a trumpeter swan in Ontario before reintroduction occurred in 1884. Among Ontarians, the Wye Marsh Wildlife Centre has is known as the Home of the Trumpeter Swan. The marsh is also an important breeding site for black terns and least bitterns.

Originally, the land had belonged to the Govan family since the late 1800s. The tract only consists of half an acre, but within the tract, the mass availability of lives oaks, hackberries, dewberry, and poison oak attracts birds such as painted buntings, red-winged blackbirds, warblers, and other passerines that can be seen during the migratory season. In addition to the Grand Isle Birding Trail, bird watchers can also see marine birds such as gulls, terns, pelicans, and other shorebirds from the Grand Isle State Park located at the northeast end of the island.

Sooty terns on South Brother South Brother, also known as Île du Sud, is a 23 ha coral island on the Great Chagos Bank atoll of the Chagos Archipelago in the British Indian Ocean Territory. It is one of the three islands in the Three Brothers group on the western side of the atoll, and forms part of the Chagos Archipelago strict nature reserve. It has been identified as an Important Bird Area by BirdLife International because of its significance as a breeding site for seabirds, including brown noddies (with 6100 breeding pairs recorded in a 2004 survey) and lesser noddies (7300 pairs).

The area has been threatened by illegal fishing operations and impacts from unauthorized tourism. Cutting down of coastal mangrove has also increased erosion, with negative effects on marine life. The archipelago is currently the focus of joint conservation and development projects by CARE and the World Wildlife Fund in cooperation with the government of Mozambique and local NGOs. These projects are aimed at preserving the environment and surrounding coral reef system, restoring fisheries, protecting breeding grounds for sooty terns, dugongs and green sea turtles, and creating a better quality of life for the people of the region.

During the War of 1812, the British forces landed on the island and told the keeper's wife, Thankful Stone, that they had nothing to fear as long as they kept the light burning. Later, the keeper, Solomon Stone, had to put the light out per order of the New London customs inspector. The British threatened to blow up the lighthouse and Stone got an order to relight the lighthouse. In 2008, the generator house for the light was renovated to be a summer house for the United States Fish and Wildlife Service interns who study the endangered roseate terns.

The elegant tern is so categorised because 95% of the population breeds on one island, Isla Rasa in the Gulf of California, and the Kerguelen tern has a population of less than 5,000 adults breeding on small and often stormy Pacific islands. Three species, the Inca, Damara, and river terns, are expected to decline in the future due to habitat loss and disturbance. Some tern subspecies are endangered, including the California least tern and the Easter Island race of the grey noddy. Most tern species are declining in numbers due to the loss or disturbance of breeding habitat, pollution and increased predation.

Curaçao is semiarid, and as such has not supported the numerous tropical species of mammals, birds, and lizards most often associated with rainforests. But birders will not be disappointed by the dozens of species of hummingbirds, bananaquits, orioles, and the larger terns, herons, egrets, and even flamingos that make their homes near ponds or in coastal areas. The trupial, a black bird with a bright orange underbelly and white swatches on its wings, is common to the island and to Curaçao. The Mockingbird, called Chuchubi in Papiamentu, resembles the North American mockingbird, with a long white-gray tail and a gray back.

Juvenile preparing to receive food from parent The California least tern hunts primarily in shallow estuaries and lagoons, or beyond the breakers, even beyond 24 km offshore in areas of upwelling, and where smaller fishes are abundant. They hover until spotting prey, and then plunge into the water without full submersion to extract prey. In the bays and lagoons of Southern California and northern Mexico, the favored prey include anchovy, smelt, silversides, shiner surfperch and small crustaceans. The terns often feed near shore in the open ocean, especially in proximity to lagoons or bay mouths (Baird 2010).

In 2002, the facility was designated a corporate wildlife habitat by the Wildlife Habitat Council. For their efforts, the Trenton Channel Power Plant and Sibley Quarry were co-awarded the Wildlife Habitat Council's Corporate Habitat of the Year award in 2004. The Trenton Channel Power Plant has also donated money and worked closely with Elizabeth Park and the Wayne County Department of Public Services for continued ecological preservation. DTE Energy spreads crushed limestone along the banks of the Detroit River on Slocum's Island, because such an item provides a popular nesting habitat for native common terns.

The founder and director of the Great Gull Island Project is Helen Hays, who has been managing the island since 1969. Joe DiCostanzo is responsible for running the database detailing the family history, hatching records, and nest location of many of the birds hatched on or visiting the island. The Great Gull Island Program has an ongoing partnership with several Argentine projects that monitor the terns during the winter and spring months. Occasionally, as a show of support, an Argentine delegation will arrive to assist in preparation work for "peak week", when hatchings-per-day can range into the thousands.

A 2000 ha tract of land on the western side of the bay has been identified as an Important Bird Area (IBA) by BirdLife International because it supports breeding colonies of several seabirds, including Adélie penguins (15,000 pairs), gentoo penguins (2300 pairs) and chinstrap penguins (2500 pairs). Other birds recorded nesting at the site are southern giant petrels Cape petrels, snowy sheathbills, kelp gulls, Antarctic terns and skuas. Southern elephant and Weddell seals breed in the area; they, as well as Antarctic fur seals, regularly haul out there. In winter leopard and crabeater seals are often seen on nearby sea ice.

Coral diversity is highest at Suluan island where 25 species hard and soft corals are found. They serve as habitats for many colonies of fish, such as barracuda, marlin and scombrid, and other marine species like marine turtles, octopus, squid and seacucumber. The Department of Environment and Natural Resources also documented the following wildlife species in the area in 2008: the Philippine tarsier and Philippine long-tailed macaque, and bird species such as the Philippine cockatoo, herons, migratory egrets, bitterns, plovers, sandpipers, gulls and terns. Several reptiles were also sighted in the area, including monitor lizards and sailfin lizards.

The refuge is home for to a wide array of bird species that either use the islands as nesting grounds or as a place of shelter. The great black-backed gull (Larus marinus) is known to have a small breeding colony on Gravel Island, and historically on Spider Island. In 1994 the species was discovered on Spider Island, making it the westernmost breeding on record at the time. Large colonies of herring gulls (Larus smithsonianus) and double-crested cormorants (Phalacrocorax auritus) are found on both islands, while a colony of Caspian terns (Sterna caspia) can be found on Gravel Island.

Eight of the islands within Maine Coastal Islands National Wildlife Refuge currently support seabird restoration projects. The primary focus of these projects is to re-establish breeding populations of common, Arctic, and roseate terns, Atlantic puffins, and razorbills on historic nesting islands. The combined efforts of the Refuge and our conservation partners have proven highly successful, and all five species have experienced significant population growth as a result of our efforts. The four mainland units are located in the Towns of Corea, Gouldsboro, Steuben, and Milbridge, Maine, and also provide a diversity of habitat for a wide variety of species.

This species is notable for laying its egg on bare thin branches in a small fork or depression without a nest. This behaviour is unusual for terns, which generally nest on the ground, and even the related tree-nesting black noddy constructs a nest. It is thought that the reason for the absence of nests is the reduction in nest parasites, which in some colonial seabirds can cause the abandonment of an entire colony. In spite of these benefits there are costs associated with tree nesting, as the eggs and chicks are vulnerable to becoming dislodged by heavy winds.

However, within the last decade, there have been reports of colony declines and disappearances at individual sites in Alaska. This species is strongly migratory, and although the wintering range is poorly known, it is believed to lie off Indonesia and Malaysia. Small flocks of the species have been increasingly sighted in coastal areas around Hong Kong in spring and fall, around Singapore and Indonesia between October and April, and in coastal waters of Java, Bali and Sulawesi during December. The regular appearance of Aleutian terns in fall off Hong Kong suggests one possible route for southbound migrants.

The tidal marsh, coves, creeks and ridges of the refuge provide an important rest area and winter home for thousands of migratory waterfowl and nesting habitat for a variety of wildlife that change with the seasons. Winter residents on the refuge include black ducks, pintail, mergansers, long-tailed ducks, scoters, bufflehead, Canada geese, and tundra swans. During spring and summer, the salt marsh grasses, abundant insects, and underwater vegetation attract black ducks, mallards, gadwall, and green-winged teal to nest on the refuge. Gulls, terns, black skimmers, oystercatchers, and willets nest and feed along the marsh grasses, mudflats, and sand bars.

Ornithologist and pioneering bird photographer Emma Turner started ringing common terns on the Point in 1909, and the use of this technique for migration studies has continued since. A notable recovery was a Sandwich tern killed for food in Angola, and a Radde's warbler trapped for ringing in 1961 was only the second British record of this species at that time. In the winter, the marshes hold golden plovers and wildfowl including common shelduck, Eurasian wigeon, brent geese and common teal, while common scoters, common eiders, common goldeneyes and red-breasted mergansers swim offshore.Allison (1989) pp. 87-88.

Wading birds, such as roseate spoonbills (Platalea ajaja), egrets, and tricolored herons (Egretta tricolor) use the mangroves as a nursery, due to the proximity of food sources and the protection offered from most prey. Thousands of birds can nest in the mangroves at once, making a noisy and messy colony, but their droppings fertilize the mangrove trees.Whitney, pp. 295–296. Shorebirds like rails, terns and gulls; diving birds such as pelicans and grebes; and birds of prey such as ospreys, hawks and vultures are among the more than 100 species of birds that use Everglades mangrove trees to raise their young.

In flight at Morro Bay, California In the Americas, the royal terns on the east coast, during the breeding season (April to July), occur in the US north to Virginia, occasionally drifting north to Long Island, New York. The southern end of their breeding range is Texas. The wintering range on the east coast is from North Carolina south to Panama and the Guianas, also the Caribbean islands. On the western coast of the Americas, the royal tern spends the breeding season from the US state of California to Mexico, wintering from California south to Peru.

Banc d'Arguin from orbit, 2019 Map of Banc d'Arguin including Tidra Island and Arguin The Banc d'Arguin National Park () of Bay of Arguin lies in Western Africa on the west coast of Mauritania between Nouakchott and Nouadhibou. The World Heritage Site is a major breeding site for migratory birds, including flamingos, broad-billed sandpipers, pelicans and terns. Much of the breeding is on sand banks including the islands of Tidra, Niroumi, Nair, Kijji and Arguim. The surrounding waters are some of the richest fishing waters in western Africa and serve as nesting grounds for the entire western region.

The black- bellied tern has long wings but its flight is slow, with much flapping. It feeds on insects and small fish, skimming over the surface of the water and ground to pick up insects, and plunging obliquely into the water to feed on crustaceans, tadpoles and fish. Breeding takes place from February to April, the nesting site usually being a flat sandy location near a river or lake, a sand spit or a sandy island. It does not nest colonially but may nest with other birds such as river terns (Sterna aurantia), pratincoles (Glareola spp.) and Indian skimmers (Rynchops albicollis).

Numerous birds frequent The Riddy, some which feed in the meadows including redwing (Turdus iliacus), fieldfare (Turdus pilaris) and northern lapwing (Vanellus vanellus), whilst sparrowhawks (Accipiter nisus) have been observed "patrolling" the mature hedgerows. Grey herons (Ardea cinerea) and common terns (Sterna hirundo) hunt fish, and in the autumn, song thrushes (Turdus philomelos) can be seen at the reserve. Grey wagtail (Motacilla cinerea) and kingfisher (Alcedo atthis) have also been recorded on the reserve. The reserve is managed by both the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire and Bedfordshire Rural Communities Charity through its volunteer group 'Ivel Valley Conservation Volunteers'.

Migratory birds: Due to there being a geographic point of interest for the migratory birds, we can watch species like the Eurasian spoonbill, Cory's shearwater, great black-backed gull, terns, Ciconiiformes and less frequent species. Amphibians, fishes and invertebrates There is a good selection of aquatic fauna, like the flathead mullet, righteye flounder and Anguillidae. Amphibians found here are the green frog, palmate newt and natterjack toad. Mammals are not as frequent in the area, but like in other places with the same type habitat there are some species of shrew, common vole, mice and the least weasel (an introduced species).

Amaranthus brownii was considered the rarest plant on Nihoa and has not been directly observed on the island since 1983, and is now considered to be extinct. The plant communities and rocky outcrops provide nesting and perching areas for 18 species of seabirds, such as red-footed boobies and brown noddies, terns, shearwaters, and petrels. Prehistoric evidence indicates Native Hawaiians lived on or visited the island around AD 1000, but over time the location of Nihoa was mostly forgotten, with only an oral legend preserving its name. Captain James Colnett rediscovered the island in 1788, and Queen Kaʻahumanu visited it in 1822.

The estuary is home to abundant marine wildlife including crustaceans such as the blue swimmer crab (Portunus pelagicus) and the western king prawn (Penaeus latisulcatus) and fish species such as black bream, mulloway, tailor and cobbler. It is occasionally visited by dolphins. The estuary has been identified by BirdLife International as an Important Bird Area (IBA) because it supports a significant population of fairy terns, is a drought refuge for blue-billed ducks, and sometimes holds over 1% of the world populations of red-necked stints, sharp-tailed sandpipers, banded stilts, red- necked avocets and red-capped plovers.

Faure Island is an important breeding area for many seabirds, as well as being important for migratory waders using the East Asian - Australasian Flyway. With the neighbouring much smaller (5 ha) Pelican Island and their associated mudflats, it has been identified as a 5821 ha Important Bird Area (IBA). The Faure and Pelican Islands (Shark Bay) IBA supports breeding colonies of fairy terns and over 1% of the world populations of red-necked stint and pied oystercatcher. Together with the nearby Quoin Bluff and Freycinet Island IBA, it supports more than 1% of the world population of pied cormorants.

The Macquarie Marshes have been identified by BirdLife International as a 2378 km2 Important Bird Area (IBA), defined by the maximum extent of the 1990 floods. Among over 200 species of birds recorded, the marshes have supported over 1% of the world population of the endangered Australasian bittern, as well as white-necked herons, intermediate egrets, nankeen night-herons, Australian white and straw- necked ibises, and sharp-tailed sandpipers. The IBA also supports a population of diamond firetails. Other birds recorded in substantial numbers include glossy ibises, great and little egrets, royal spoonbills, Pacific black ducks and Caspian terns.

Wooded and semi-wooded areas attract redstart, pied flycatcher, wood warbler and tree pipit, and coniferous plantations house siskin and common crossbill. Upland reservoirs in the Dark Peak are generally oligotrophic and attract few birds, but lower-lying reservoirs on the southern fringes such as Carsington Water and Ogston Reservoir regularly attract rare migrants and wintering rarities such as various waders, wildfowl, gulls and terns. The area is regularly overflown by wintering populations of pink-footed geese moving between East Anglia and Morecambe Bay. Dipper, golden plover, hen harrier, merlin and short-eared owl are local biodiversity action plan priority species.

The site has been identified by BirdLife International as an IBA because it regularly supports critically endangered orange-bellied parrots on their annual migration between the breeding ground in South West Tasmania and the wintering sites in coastal mainland south-eastern Australia. It also provides non-breeding habitat for swift parrots and supports populations of fairy terns, hooded plovers, Cape Barren geese and pied oystercatchers, as well as most of Tasmania's endemic bird species. Other birds recorded from the site include sooty oystercatchers, eastern ground parrots, flame and pink robins, tawny-crowned honeyeaters and southern emu- wrens.

The establishment, in 1975, of the Castro Marim and Vila Real de Santo António Marsh Natural Reserve provided a refuge for several species of migratory and marine birds, namely mallards, flamingos, Kentish plovers, little terns, pied avocets, dunlins, stilts, white storks, and spoonbills, while at the same time protecting breeding grounds for local fish and crustaceans. Chameleons, oysters, and jellyfish (of the genus Rhopilema) are among the species that can be found in the region and its coastal waters, while carob trees, gum rockrose, brooms and almond trees mingle within the forests and brush within the interior.
|
|
Other species that have been noted there include dunlin, sanderling, Eurasian whimbrel, several (escaped) flamingos, pied avocets and on one occasion a glossy ibis. There is a bird observation hide at the east end of Breydon Water, on the north shore, looking out towards a breeding platform used mainly by common terns. Other breeding species include common shelducks, northern shovelers, Eurasian oystercatchers and yellow wagtails. The naturalist Arthur Henry Patterson A.L.S. (1857–1935), who published under the pseudonym 'John Knowlittle', extensively documented the wildlife of Breydon and the disappearing lifestyles of those boatmen, wildfowlers and fishermen who made a living from the estuary.

The island has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a large and diverse population of breeding seabirds and other waterbirds. It is the only known breeding site outside Aldabra and Madagascar for Malagasy pond herons. Seabirds include the second largest colony in the western Indian Ocean of great frigatebirds (with up to 1100 pairs), Audubon's shearwaters (up to 100 pairs, probably of the subspecies Puffinus lherminieri bailloni previously considered endemic to the Mascarene Islands), dimorphic egrets and Caspian terns. The island is also home to an endemic subspecies of white-tailed tropicbird (Phaethon lepturus europae).

Birds in their first post-juvenile plumage, which normally remain in their wintering areas, resemble the non-breeding adult, but have a duskier crown, dark carpal bar, and often very worn plumage. By their second year, most young terns are either indistinguishable from adults, or show only minor differences such as a darker bill or white forehead. The common tern is an agile flyer, capable of rapid turns and swoops, hovering, and vertical take-off. When commuting with fish, it flies close to the surface in a strong head wind, but above the water in a following wind.
|
|
Old primary feathers wear away to reveal the blackish barbs beneath. The moult pattern means that the oldest feathers are those nearest the middle of the wing, so as the northern summer progresses, a dark wedge appears on the wing due to this feather ageing process. Terns are unusual in the frequency in which they moult their primaries, which are replaced at least twice, occasionally three times in a year. The visible difference in feather age is accentuated in the greater ultraviolet reflectance of new primaries, and the freshness of the wing feathers is used by females in mate selection.

The eggs may be laid on bare sand, gravel or soil, but a lining of debris or vegetation is often added if available, or the nest may be rimmed with seaweed, stones or shells. The saucer-shaped scrape is typically deep and across, but may extend to as much as wide including the surrounding decorative material.Hume (1993) pp. 100–111. Breeding success in areas prone to flooding has been enhanced by the provision of artificial mats made from eelgrass, which encourage the terns to nest in higher, less vulnerable areas, since many prefer the mats to bare sand.

The coasts of the North Sea are home to nature reserves including the Ythan Estuary, Fowlsheugh Nature Preserve, and Farne Islands in the UK and the Wadden Sea National Parks in Denmark, Germany and the Netherlands. These locations provide breeding habitat for dozens of bird species. Tens of millions of birds make use of the North Sea for breeding, feeding, or migratory stopovers every year. Populations of black-legged kittiwakes, Atlantic puffins, northern gannets, northern fulmars, and species of petrels, seaducks, loons (divers), cormorants, gulls, auks, and terns, and many other seabirds make these coasts popular for birdwatching.

Up to 60,000 pied imperial-pigeons breed on the islands during summer, providing a spectacle to onlookers as they return to their nests each evening after foraging for rainforest fruits in the mainland and Hinchinbrook Island. Following regular illegal shooting of the birds there during the early and mid 20th Century, the population using the islands was subject to a long protection campaign and monitoring program by conservation activists Margaret and Arthur Thorsborne. There are also breeding colonies of bridled, black-naped, little, lesser crested and roseate terns. Beach stone-curlews breed on North Island beaches.

A French exploration map of 1732 showed an elongated barrier spit between Petit Bois Island and Dauphin Island This connection was breached between 1740 and 1766, possibly as the result of the 1740 hurricane. Petit Bois originally extended about east of the Alabama-Mississippi state line and was effectively located in both states. From 1933 to 1968, the eastern end of the island eroded (due to the effects of hurricanes and natural shoreline movement) until it was west of the Mississippi state line. The island is approximately long and serves as a habitat for gulls, terns, plovers, alligators, and other wildlife.

One species, the ancient murrelet, fledges two days after hatching, running from its burrow to the ocean and its calling parents. Once it reaches the ocean, its parents care for it for several weeks. Other species, such as guillemots and terns, leave the nesting site while they are still unable to fly. The fledging behavior of the guillemot is spectacular; the adult leads the chick to the edge of the cliff, where the colony is located, and the chick will then launch itself off, attempting to fly as far as possible, before crash landing on the ocean.

The Te Arai North Ltd owned Tara Iti Golf Club was built nearby fairy terns nesting area. The bird is further threatened by a proposed residential subdivision at Te Arai, next to one of its prime breeding sites. As part of its Treaty settlement, Te Uri o Hau purchased land in the Mangawhai Forest, and signed a co-governance agreement with developer Te Arai North. Two thousand homes were originally proposed for the development, however after opposition from The Te Arai Beach Preservation Society, Fairy Tern Charitable Trust, and others, this was scaled back to 46 homes and a 196-hectare public park.

Lakes in central Massachusetts provide habitat for the common loon, while a significant population of long-tailed ducks winter off Nantucket. Small offshore islands and beaches are home to roseate terns and are important breeding areas for the locally threatened piping plover. Protected areas such as the Monomoy National Wildlife Refuge provide critical breeding habitat for shorebirds and a variety of marine wildlife including a large population of gray seals. Freshwater fish species in the commonwealth include bass, carp, catfish, and trout, while saltwater species such as Atlantic cod, haddock and American lobster populate offshore waters.

Antarctica, also known as the southern pole, is larger and can become much colder than the northern pole. As a result, few animals can survive on the mainland of Antarctica, and those that do mostly live near the coast. The few animals that live on the mainland are birds such as Antarctic terns, grey-headed albatross, imperial shag, snowy sheathbill and the most well known inhabitant of Antarctica, penguins. The inhospitable environment helps to deter predators; the few predators that hunt on the mainland, including the south polar skua and the southern giant petrel, mainly prey upon chicks.

The core of the wetland system has been identified as an Important Bird Area (IBA) by BirdLife International because it supports over 200,000 waterbirds when extensively flooded. It has periodically supported over 1% of the world populations of Australian pelicans and straw-necked ibises, their breeding colonies being among the largest recorded in the Australian tropics. Other birds which have bred in the IBA in relatively large numbers include freckled ducks, great and intermediate egrets, glossy ibises, Australian terns, magpie geese, plumed whistling-ducks, grey teals and hardheads. Nationally vulnerable Australian painted snipes bred at Tarrabool in 1993.

The beaches of the Bight's islands are important for nesting terns and for marine turtles, for which the site is considered to be of national significance. The extensive coastal mudflats provide feeding habitat for flocks of over 30,000 migratory waders, or shorebirds, and the freshwater swamps of the river floodplains are used by tens of thousands of waterbirds. The coastal waters support high densities of dugongs. Threatened vertebrate species found in the area include the Australian bustard, masked owl, partridge pigeon and northern hopping mouse, as well as the flatback, green, hawksbill and olive ridley turtles.

The island has been identified as an Important Bird Area by BirdLife International because it supports a breeding colony of about 4600 pairs of gentoo penguins, as well as smaller numbers of Adélie and chinstrap penguins, southern giant petrels, Wilson's and black-bellied storm petrels, Cape petrels, brown and south polar skuas, and Antarctic terns. A 2016 study examined lake guano sediments and studied penguin population dynamics over 7,000 years. Three of five population growth phases were terminated by a sudden crash, due to volcanic eruptions from the active volcano of Deception Island, 120 km to the southwest.

Dakhla Peninsula and Cintra Bay are some of the most important wintering grounds for birds especially for waders. The greater flamingo is one of the most iconic birds in the region and there are numerous others known to migrate or inhabit. Some of these are; pelican, great cormorant, gulls (slender-billed, Audouin's, black-backed), larks (sparrow, bar-tailed), terns (little, Caspian, royal, Sandwich), black wheatear, western reef heron, marsh harrier, sparrowhawk, lesser kestrel, laughing dove, great spotted cuckoo, little swift, hoopoe, rock martin, cricket longtail, oystercatcher, bar-tailed godwit, pharaoh eagle owl, and red-knobbed coot.Punkbirder (Team Desert Storm). 2010.

Cantão State Park includes 24 sandy islands on the Araguaia river, as well as a large number of river sand beaches on bends of the channels that weave through the interior of the park. The sand itself is the primary habitat for a number of species. Black skimmers, yellow-billed terns, yellow-spotted river turtles, the enormous Amazon river turtle, and other species nest directly on the sand in great numbers. Their eggs attract nest predators like the southern caracara, the tayra, and even the jaguar, which also takes adult turtles at night when they climb up onto the beach to nest.

At one time the site was used for nesting by thousands of common murre (Uria aalge), but due to egg collecting and illegal hunting by 2010 there were only 12 of these birds in the sanctuary. Terns are sometimes the most common birds in the sanctuary, with 1,800 counted in 2005. Other birds that form colonies on the islands include Atlantic puffin (Fratercula arctica), black guillemot (Cepphus grylle), razorbill (Alca torda), American herring gull (Larus smithsonianus), great black-backed gull (Larus marinus), black-legged kittiwake (Rissa tridactyla), great cormorant (Phalacrocorax carbo) and double-crested cormorant (Phalacrocorax auritus).

Nowadays, no foxes or other predatory mammals can be seen at Seal Beach National Wildlife Refuge. Toxic Contamination In 1995, there was a study that U.S Navy has found elevated levels of toxic chemicals in the carcasses and food of endangered birds at the Seal Beach National Wildlife Refuge. The elevated levels of cadmium, chromium, copper, lead, nickel and zinc, all poisonous heavy metals, were found in dead California least terns and light-footed clapper rails. However, these potentially toxic substances were not only found in the birds, but also found in smaller animals normally eaten by them.

It eats smaller (biotic) animals and plants – small crustaceans, algae, annelid worms, shrimp, zooplankton, copepods, amphipods, squid, and insects. The Atlantic silverside's predators are larger predatory fish – striped bass, blue fish, Atlantic mackerel – and many shore birds, including egrets, terns, cormorants, and gulls. The abiotic factors the Atlantic silverside needs to survive varies for populations of fish based on their geographical location. A rule of thumb for the species includes an average temperature of , a salt content of the water ranging from 0 to 37ppt (Tagatz and Dudley 1961), and a well-mixed body of water to prevent hypoxic conditions.

The waters of the Colville delta, along with the waters of Harrison Bay, make an ideal refuge for long-tailed ducks, king eiders, red-throated loons, Arctic terns, surf scoters, brant geese, and glaucous gulls.Smith, M., N. J. Walker, I. J. Stenhouse, C. M. Free, M. Kirchhoff, O. Romanenko, S. Senner, N. Warnock, and V. Mendenhall, ["A new map of Important Bird Areas in Alaska"], 16th Alaska Bird Conference, Juneau, AK, 2014. Retrieved 15-09-2016. In summer and fall, migrating red-throated and yellow-billed loons and king and spectacled eiders stop in to rest and feed.

Bearded reedling The key breeding species are reed bed specialists such as the marsh harrier, Eurasian bittern and bearded reedling, and the island-nesting avocet. Other birds nesting in the wetland include northern lapwing, common redshank and sedge, reed and Cetti's warblers. Eurasian spoonbills, ruffs and black-tailed godwits are present for much of the year, and a pair of little egrets bred for the first time in 2010–2012. Spring migrants including little gull, black tern, Temminck's stint and garganey may pass through on their way to breed elsewhere, and terns frequently visit from the colonies on Blakeney Point.

Alternative compensation systems have two very significant advantages over digital copyright. They do not impose artificial scarcity on copyright works: everyone can download as many songs, ebooks and films as they want (in economic terns, ACS eliminate the deadweight loss of copyright monopolies). They also avoid the very high technological and social costs of digital copyright enforcement. The two greatest drawbacks of ACSes are the excess burden of the taxation that is collected, and the need to decide what tax/levy rates to use for the system (although methods such as contingent valuation may help a little with that question).

Over 600 plant species have been identified, including the endangered Cynometra lukei and Gonatopus marattioides. Tana River delta is one of the only estuarine staging posts on the Asian–East African Flyway, it is a critical feeding and wintering ground for several migratory waterbirds such as waders, gulls and terns. The main anthropogenic activities include fishing, small-scale family-oriented agriculture, mangrove wood exploitation, grazing, water supply, tourism and research (ongoing research on the protection and monitoring of breeding turtles and the conservation of dugongs). The Tana River delta is also an Important Bird Area (IBA).

Another conservation effort is habitat management to encourage the red-necked phalarope. The white-tailed eagle, re-introduced in 2007 following a 200-year absence from Ireland. South- eastern Wexford is an important site for birds - the north side of Wexford Harbour, the North Slob, is home to 10,000 Greenland white-fronted geese each winter (roughly one third of the entire world's population), while in the summer Lady's Island Lake is an important breeding site for terns, especially the roseate tern. Three quarters of the world population of pale bellied brent geese winter in Strangford Lough in County Down.

"Environment Plan 2012 - 2017" (PDF) Phillip Island Nature Parks. Retrieved 2016-05-01. It is home to one of the largest Little Penguin (Eudyptula minor) breeding colonies in Australia, the second largest breeding colony of Australian Fur Seals (Arctocephalus pusillus doriferus) in the world, one of the largest breeding colonies of Greater crested terns (Sterna bergii) in Victoria and an important breeding ground for Short-tailed shearwaters (Puffinus tenuirostris). Several plants regarded as rare or threatened in either Victoria or Australia have been recorded on the peninsula, including River Swamp Wallaby-grass (Amphibromus fluitans) listed as vulnerable in Australia.

Jarvis Island was once one of the largest breeding colonies in the tropical ocean, but guano mining and the introduction of rodents have ruined much of the island's native wildlife. Just eight breeding species were recorded in 1982, compared to thirteen in 1996, and fourteen species in 2004. The Polynesian storm petrel had made its return after over 40 years absent from Jarvis Island, and the number of Brown noddies multiplied from just a few birds in 1982 to nearly 10,000. Just twelve Gray-backed terns were recorded in 1982, but by 2004, over 200 nests were found on the island.

Goyder Lagoon is located within an area of which has been identified by BirdLife International as an Important Bird Area (IBA) principally because, when flooded, it supports large numbers of waterbirds, with a total of 170,000 estimated from aerial surveys in 2002. The IBA supports over 1% of the world populations of freckled ducks, Australian terns and breeding royal spoonbills. A small population of yellow chats occurs at the Koonchera waterhole. Other bird species for which the site is important include the letter-winged kite, inland dotterel, grey and Eyrean grasswrens, black and pied honeyeaters, gibberbird, banded whiteface, chirruping wedgebill and cinnamon quail-thrush.

The Wadden Sea is famous for its rich flora and fauna, especially birds. Hundreds of thousands of waders, ducks, and geese use the area as a migration stopover or wintering site. It is also a rich habitat for gulls and terns, as well as a few species of herons, Eurasian spoonbills and birds-of-prey, including a small and increasing breeding population of white-tailed eagles. However, the biodiversity of Wadden Sea is smaller today than it once was; for birds, greater flamingos and Dalmatian pelicans used to be common as well, at least during the Holocene climatic optimum when the climate was warmer.

Sea birds such as oystercatchers and terns nest in the cliffsides and circle on the wind down to the water. A sea cave provides another opportunity for exploration. The steps were repaired early in the 19th century and again very recently. The late Etta Juhle cleared about 30 tons of rubble by herself in 1975 after a landslip and David Nicolson of Ulbster has worked continuously on the steps with local historian Iain Sutherland and many other volunteers since 1998, repairing the barking kettles, quarrying stone, manually carrying it up or down the cliffs and grass-cutting about every three weeks during the summer season.

Flying subadult silver gulls at Kiama beach, Sydney during Christmas 2013 A gull in flight Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. They are most closely related to the terns (family Sternidae) and only distantly related to auks, skimmers and even more distantly to waders. Until the 21st century, most gulls were placed in the genus Larus, but that arrangement is now considered polyphyletic, leading to the resurrection of several genera. An older name for gulls is mews, which is cognate with German Möwe, Danish måge, Swedish mås, Dutch meeuw, and French mouette, and can still be found in certain regional dialects.

While some species use the leg over the lowered wing to reach the head, others extend the leg more directly between the wing and the body. In general, these activities take place while the bird is either perched, on the ground, or swimming, but some of the more aerial species (including swallows, terns and albatrosses) preen on the wing. Many birds have a slight overhang at the tip of their upper mandible. Experiments suggest that this allows birds to apply shearing forces that kill the flattened feather lice; the removal of the bill tip caused an increase in feather lice due to ineffective preening.

Because fully-grown feathers are essentially dead structures, it is vital that birds have some way to protect and lubricate them. To facilitate this, many species have a preen or uropygial gland, which opens above the base of the tail feathers and secretes a substance containing fatty acids, water, and waxes. The bird gathers this substance on its bill and applies it to its feathers. The gland is generally larger (in relation to body size) in waterbirds, including terns, grebes and petrels, but studies have found no clear correlation between the size of a bird's gland and the exposure to water that its lifestyle dictates.

This may pose a risk to these birds because zebra mussels are efficient filter feeders and so accumulate environmental contaminants rapidly. They nest in a sheltered location on the ground near water, usually among thick vegetation such as sedges and bulrushes, sometimes in small loose groups and not rarely next to colonies of gulls or terns; several females may deposit eggs in a single nest. The drakes court the hens in the winter quarters; pairs form shortly before and during the spring migration. When nesting starts, the males aggregate while they moult into eclipse plumage, leaving the task of incubation and raising the young to the females alone.

An additional four endemic species inhabit two or more of the islands, including the Príncipe speirops (Speirops leucophoeus) and velvet-mantled drongo (Dicrurus modestus), which inhabit both São Tomé and Príncipe, and the São Tomé bronze-naped pigeon (Columba malherbii) which inhabits both São Tomé and Annobón. The Tinhosas islands are home to the largest seabird colonies in the Gulf of Guinea, with breeding colonies of sooty terns (Onychoprion fuscatus, 100,000 breeding pairs), black noddies (Anous minutus, 10,000–20,000 breeding pairs), brown noddies (Anous stolidus, 4,000–8,000 breeding pairs), brown boobies (Sula leucogaster, 1,500–3,000 breeding pairs) and small numbers of white-tailed tropicbirds (Phaethon lepturus).

The island is closed to visitors from 1 October until Easter to prevent disturbance to the large number of seal pups. The Scottish Seabird Centre at North Berwick has two live cameras on the island, which can be remotely controlled by visitors, to allow close viewing of the seabird cities, including puffins, guillemots, razorbills, shags, cormorants and terns and the fluffy grey seal pups in winter, without disturbance. The Scottish Seabird Centre also runs boat trips to the Isle of May. As well as its natural heritage, the Isle of May also has a rich cultural heritage, including St Adrian's Chapel, which is a Scheduled Ancient Monument.

Many species of lark live on the steppe, including the rare Dupont's lark (Chersophilus duponti) and there are also little bustards (Tetrax tetrax) and stone curlews (Burhinus oedicnemus). Sea birds include yellow-legged gulls (Larus michahellis), terns, razorbills (Alca torda), shags, the occasional puffin (Fratercula arctica) and Cory's (Calonectris diomedea) and Balearic shearwaters (Puffinus mauretanicus). The wealth of animal life provides prey for a number of raptors: ospreys (Pandion haliaetus), peregrine falcons (Falco peregrinus), kestrels (Falco tinnunculus), and eagles. Approximately 15 species of reptile are found in the park, including Italian wall lizards (Podarcis sicula), ocellated lizards (Timon lepidus), grass snakes (Natrix natrix), and Lataste's viper (Vipera latastei).

A major stopover for birds following the Atlantic Flyway, Great Gull Island was the home of large colonies of nesting terns up until the end of the 19th century, when many birds were killed as a result of the millinery trade and the construction of military fortifications on the island. In 1897, Fort Michie was constructed on Great Gull Island as part of the Coast Defenses of Long Island Sound. The military base was operational from the Spanish–American War through World War II. It included one of the largest gun installations in the United States, an emplacement for a 16-inch gun on a disappearing carriage.Fort Michie at FortWiki.

The bay, with part of the south-western slopes of Mont Ross, has been identified as a 20 km2 Important Bird Area (IBA) by BirdLife International because of its breeding seabirds. Of the penguins, there are some 21,500 pairs of kings, 500 pairs of gentoos, 6000 pairs of macaronis and 4000 pairs of eastern rockhoppers. Other birds nesting in the IBA include a few pairs of wandering albatrosses, Antarctic and slender-billed prions, white-chinned, northern giant and common diving petrels, Kerguelen shags, Kerguelen terns, black-faced sheathbills and Eaton's pintails. Antarctic fur seals and southern elephant seals also breed on the shores of the bay.

While some islands provide dense stands of red spruce and balsam fir for nesting bald eagles and wading birds, other islands provide great expanses of mixed grasses and raspberries which support nesting terns, common eiders, and a number of neotropical migrants. The rocky ledges surrounding the islands provide nesting habitat for Atlantic puffins, razorbills, and black guillemots. The inter- tidal areas surrounding the islands and mainland properties provide an abundance of invertebrates for migratory and wintering waterfowl and shorebirds. The diversity of upland habitats and the extensive inter-tidal habitats combine to provide foraging, breeding, and migratory habitat for over 320 species of birds.

South Brother island in the Chagos Archipelago Seventeen species of breeding seabirds can be found nesting in huge colonies on many of the islands in the archipelago, and 10 of the islands have received formal designation as Important Bird Areas, by BirdLife International. This means that Chagos has the most diverse breeding seabird community within this tropical region. Of particular interest are the large colonies of sooty terns (Sterna fuscata), brown and lesser noddies (Anous stolidus and Anous tenuirostris) wedge-tailed shearwaters (Puffinus pacificus) and red-footed boobies (Sula sula). Land bird fauna is poor and consists of introduced species and recent natural colonisers.

In 1972, the Fish and Wildlife Service reconstructed the dam to maintain the integrity of the structure and to assure continued maintenance of the open water, marsh, and wetland areas created by the original dam. A natural overflow near the structure provides an additional escape route for high water thereby affording extra protection for the dam and control structures. A right-of-way provides access to the dam for maintenance and public use. Carlton Pond is one of the few areas in the state which provides nesting habitat for black terns, which are on the endangered species list maintained by the State of Maine.

The Aleutian tern has been designated as a species of concern by several agencies and NGOs (Alaska Department of Fish and Game, Audubon Alaska, U.S. Fish and Wildlife Service, The North American Waterbird Conservation Plan). In 2007, an Aleutian tern Working Group was organized in Alaska in order to examine the necessity to develop an accurate population estimation method and therefore prioritizing the management of the species and the identification of its migration pathway. In 2010, they began to deploy geolocators on Aleutians terns from colonies in Alaska. The lack of data on breeding biology and ecological behaviours limits the development of conservation actions for the species.

The Point has been studied for more than a century, following pioneering ecological studies by botanist Francis Wall Oliver and a bird ringing programme initiated by ornithologist Emma Turner. The area has a long history of human occupation; ruins of a medieval monastery and "Blakeney Chapel" (probably a domestic dwelling) are buried in the marshes. The towns sheltered by the shingle spit were once important harbours, but land reclamation schemes starting in the 17th century resulted in the silting up of the river channels. The reserve is important for breeding birds, especially terns, and its location makes it a major site for migrating birds in autumn.

A female entering the nest area reacts passively to the male's aggression, enabling him to recognise her sex and initiate pair formation by display, including head raising and bowing; this behaviour is frequently repeated during nesting to reinforce the bond between the pair. Terns also use fish as part of the courtship ritual. One bird flies around the colony with a fish in its beak, calling loudly; its partner may also fly, but the pair eventually settle and the gift is exchanged. Breeding plumage in New South Wales The nest is a shallow scrape in the sand on open, flat or occasionally sloping ground.

The forehead and the underparts are white, the back and inner wings are dusky-grey. In winter, the upperparts plumage wears to a paler grey, and the crown of the head becomes white, merging at the rear into a peppered black crest and mask. The adults of both sexes are identical in appearance, but juvenile birds are distinctive, with a head pattern like the winter adult, and upperparts strongly patterned in grey, brown, and white; the closed wings appear to have dark bars. After moulting, the young terns resemble the adult, but still have a variegated wing pattern with a dark bar on the inner flight feathers.

He also was active as a research officer at the EGI until 1963. Through the mediation of David Lack, who worked with G. Evelyn Hutchinson at the EGI, Ashmole received a summer research fellowship at the Peabody Museum of Yale University. Subsequently, the Ashmoles spent a year in Hawaii on a Yale fellowship at the Bernice P. Bishop Museum from where they studied feeding ecology and breeding cycles of terns and other seabirds on Kiritimati, as well as trying to assess the effects of nuclear weapons testing on sea birds. Subsequently, Ashmole served as assistant and associate professor at Yale University, where he did research work until 1972.

The Gulf-side beaches are excellent on both Sanibel and Captiva, and are world-renowned for their variety of seashells, which include coquinas, scallops, whelks, sand dollars, and many other species of both shallow-water and deeper-water mollusks, primarily bivalves and gastropods. Sanibel Island is home to a significant variety of birds, including the roseate spoonbill and several nesting pairs of bald eagles. Birds can be seen on the beaches, the causeway islands, and the reserves, including J. N. "Ding" Darling National Wildlife Refuge. Common sights include pelicans, herons, egrets, and anhingas, as well as the more common birds like terns, sandpipers, and seagulls.

The 2nd page of the brochure The 3rd page of the brochure The last page of the brochure Young Painters of the World was a sort of residency program for young artists under 30 age from member countries of UNESCO. It was supported by UNESCO and organized by each national committee of IAA/AIAP in terns. Because of the lack of archive material, it is not clear who brought up the idea first, and when and where it started.

Fort Michie and its unique 16-inch disappearing emplacement are well preserved, but the island is owned by the American Museum of Natural History to study migratory terns, and can only be visited by prior arrangement. Much of Fort Terry was reused by the Animal Disease Center and the batteries remain intact, but Plum Island's future is uncertain and it currently requires prior arrangement to visit. Fort Tyler was used as a bombing range in World War II; its island is little more than a sandbar and has shifted, thus severely damaging the fort. Camp Hero is well preserved with several fire control towers, some disguised as seaside cottages.

The construction of the barrage resulted in the old Eider estuary becoming the Katinger Watt nature reserve; on the opposite side of the river in 1989 the Dithmarscher Eiderwatt was established in order to at least partially compensate for the losses of salt meadows and mudflats caused by the building of the barrage. Many fishing smacks were moved from Tönning to the fishing port by the barrage which was closer to the fishing grounds. At the barrage itself there is a large breeding colony of Arctic terns with 143 breeding pairs in 2006. The barrage is also the closing scene of the 1977 Wim Wenders film The American Friend.

The Larne Lough Ramsar site (wetlands of international importance designated under the Ramsar Convention), is 395.94 hectares in area, at latitude 54 48 54 N and longitude 05 44 38 W. It was designated a Ramsar site on 4 March 1997. The Ramsar site boundary entirely coincides with both that of the Larne Lough Area of Special Scientific Interest and the Larne Lough Special Protection Area. The site qualified under Criterion 2 of the Ramsar Convention because it supports numbers of vulnerable and endangered Irish Red Data Book bird species. The site regularly supports nationally important numbers of breeding populations of roseate terns and common tern.

When George Ord first described Bonaparte's gull in 1815, he gave it the scientific name Sterna philadelphia, assigning it to the genus now used for medium-sized terns. Most later taxonomists assigned it to the genus Larus, a longtime catch-all for most of the gull species. However, in 1858, George Newbold Lawrence moved the species to the genus Chroicocephalus, and some taxonomists followed suit. Recent molecular DNA studies have shown that this species fits neatly into a clade with other "masked gulls", and that it and the slender-billed gull are each other's closest relatives and are basal to the rest of that grouping.

The black-bellied tern (Sterna acuticauda) is a tern found near large rivers in the Indian subcontinent, its range extending from Pakistan, Nepal and India to Myanmar. It has become very scarce in the eastern part of its range and the International Union for Conservation of Nature has assessed its conservation status as being endangered. They have a black belly in the summer and a deep forked tail. They can sometimes resemble whiskered terns (Chlidonias hybrida), but the deeper fork of the tail and the black on the lower belly distinguish them from the shallow fork and black closer to the breast on the whiskered tern.

A pair of brolgas amongst other waterbirds in the Northern Territory The lake serves as a major migratory stop-over area for a variety of shorebirds. It also provides a major breeding habitat of several species of water birds, including cormorants and terns. It has been identified by BirdLife International as an Important Bird Area (IBA) because it supports over 1% of the world populations of hardheads, grey teals, pink-eared ducks, little black cormorants, brolgas, sharp-tailed sandpipers. It sometimes supports similarly important numbers of magpie geese, Pacific black ducks, freckled ducks and Oriental plovers, as well as providing habitat for Australian bustards.

As of 1996, Penguin Island was reported as accommodating breeding populations of little penguins, crested terns, short-tailed shearwaters and silver gulls.Robinson et al, 1996, pages 315 In addition to being notable as being a breeding ground for seabirds, the island is also known as a site for the study of both the crested tern and the silver gull. The crested tern and silver gull population has been the subject of banding programs respectively since 1953 and 1968.Robinson et al, 1996, pages 88Robinson et al, 1996, pages 82 Feral birds such as starlings and feral pigeons have also been recorded on Penguin Island.

Breeding adults have pale grey upperparts, very pale grey underparts, a black cap, orange-red legs, and a narrow pointed bill that can be mostly red with a black tip, or all black, depending on the subspecies.Hume (1993) pp. 21–29. The common tern's upperwings are pale grey, but as the summer wears on, the dark feather shafts of the outer flight feathers become exposed, and a grey wedge appears on the wings. The rump and tail are white, and on a standing bird the long tail extends no further than the folded wingtips, unlike the Arctic and roseate terns in which the tail protrudes beyond the wings.

Birds which have been spotted by the Malaysian Nature Society (Kuching Branch) at Buntal include a variety of plovers, sandpipers, egrets, terns, and other rare migrants, while resident birds include collared kingfisher, the white-bellied sea eagle, and brahminy kite. National parks in Kuching include the Bako National Park and the Kuching Wetlands National Park as well as the Semenggoh Wildlife Centre which operates an orangutan orphanage and rehabilitation program. Also available near Kuching are the Gunung Gading National Park and the Kubah National Park. Located about 40-minutes drive from Kuching is Santubong, a prominent beach resort area home to numerous world-class beach resorts.

An example is the white-fronted tern (Sterna striata) which has the colloquial name "kahawai bird" because often feeds on shoaling fish in association with kahawai, gulls and shearwaters. Fishermen hunting for schools of kahawai to troll look out for the flocks of white-fronted terns feeding in association with the predatory fish. The Australian population of this species spawns in the surf zone between Lakes Entrance in Victoria and Bermagui in New South Wales in the late spring and summer. The first spawn when they are around four years old and have attained a length of / They can live for up to 26 years.

It is a sanctuary for nesting seabirds of thirteen species—some of the most important nesting seabird colonies in the U.S. Over 1.2 million individuals nest in colonies here, more than on the California and Washington coasts combined. The most prevalent species are black-and-white common murres, tufted puffins, rhinoceros and Cassin's auklets, pigeon guillemots, Leach's storm-petrels, several species of gulls, and Caspian terns. Four species of pinniped breed, molt, and rest on these lands, including harbor seals, Steller and California sea lions. The southern portion of the refuge provides the greatest number of breeding and pupping sites for Steller sea lions in the U.S. outside Alaska.

Großer Knechtsand off the Weser estuary Sandwich terns on the Großer Knechtsand The Großer Knechtsand is a large sandbank beyond the Weser and Elbe estuaries (in the Elbe-Weser Triangle) in the eastern part of Lower Saxony's Wadden Sea off the coast of North Germany. It lies between the islands of Mellum (which is to the southwest) and Neuwerk ( northeast). The central area of the sandbank lies above the high water mark, forming the Hochsand of Hoher Knechtsand, which was formerly an island. The Hochsand lies 11 km west of the village of Berensch on the nearest part of the mainland in the borough of Cuxhaven in the Land Wursten.

The refuge, along with the Great White Heron National Wildlife Refuge, represents the last of the offshore (and raccoon-free) islands in the lower Florida Keys available as critical nesting, roosting, wading and loafing habitat to over 250 avian species — particularly wading birds. The area managed is overwhelmingly (99 percent) marine environment including large sand flats surrounding the islands that are used extensively by wading birds when they forage. The refuge protects habitat for a wide variety of birds, including nesting or wintering populations of terns, magnificent frigatebirds, white-crowned pigeons, ospreys, and great white herons. Several federally listed species are monitored, such as piping plovers and bald eagles.

Hal Jos (1951): Terns at the beach of Sylt The later artist Hal Jos started with cartoons before he could read and write. As an older child he painted animals in their natural environment and as a youth became interested in applied graphics. In recent years he uses metals, bones and other materials besides acrylic paint for collages and "semicollages". He took part in exhibitions in Kunsthalle Tübingen and Kunsthalle Basel and in Sofia (Bulgaria); he had several individual exhibitions in Bielefeld (Center for Interdisciplinary Studies 2004, University 2012), Freiburg 2008 ("You are welcome – Mad City 1968-1970", Carl Schurz Haus) and in a number of galleries in Southern Germany.

USACE finally issued the permit on November 15, over a year after OTA applied for it. One stipulation the USACE placed on the permit, however, was that no work in the Arkansas riverbed could take place after May 1 if it would interfere with the interior least tern nesting period, which was possible if the birds selected nesting sites around the bridge site. As a result, OTA worked to complete the bridge as quickly as possible to avoid the possibility of having to suspend the construction. By April 1991, work in the riverbed was mostly complete, with the remaining work on the bridge posing no threat to the terns.

Wash margins, brackish water reed beds, salt marshesBiotopbogen Degenerierte Salzwiese östlich der Insel Beuchel (PDF) and steep coastsAls Beispiel: Biotopbogen Steilküste nordwestlich von Neuendorf (PDF) are typical of the nature reserve. To the east of the area is sandy calcareous grassland with cottonrose or Dillenius' speedwell. The island of Beuchel is an important breeding ground for many bird species, such as ducks, geese, swans, mergansers, waders, gulls and common and Sandwich terns. The Neuendorfer Wiek protects the island from disturbance and is also of great importance as a breeding ground for other species such as great crested grebe, coot, pochard, marsh harrier, reed warbler, bearded and penduline tit.

Many birds are found on Sheffield Island and more than elsewhere, according to a brochure published in 2001 by the South Western Regional Planning Agency, but according to a July 2007 article in Darien, New Canaan & Rowayton magazine, Cockenoe island is now the largest home for birds, who have been in decline on the other islands. Sheffield Island, according to the planning agency brochure, has a "considerable nesting potential" for osprey, herons and other migratory species. Many wading birds, shore birds, songbirds and terns live on the island, including the roseate tern. Brant, scoters, black duck and other waterfowl can be found in the waters surrounding the island.

The Sturnidae differ from most birds in that they cannot easily metabolise foods containing high levels of sucrose, although they can cope with other fruits such as grapes and cherries. The isolated Azores subspecies of the common starling eats the eggs of the endangered roseate tern. Measures are being introduced to reduce common starling populations by culling before the terns return to their breeding colonies in spring. An adult foraging and finding food for young chicks There are several methods by which common starlings obtain their food but for the most part, they forage close to the ground, taking insects from the surface or just underneath.

9 February Species seen: flowers (viper's bugloss, birds-foot trefoil, restharrow, hedge woundwort, marsh cinquefoil), toads, sandhoppers, water vole, puffins, Arctic terns, kittiwakes, shags and guillemots. For the last in the series, Oddie visited the "last county before Scotland", which held memories for him as he walks past the house that used to be Monks House Bird Observatory (you can read about his experiences there in Bill Oddie's gone Birding). It was while staying here that Oddie discovered Hauxley Nature Reserve, where the owner of the Observatory showed him a variety of plantlife. Plants such as viper's bugloss, which has been used to cure snake bites, and restharrow, named because of its habit of seizing up the plough's harrow.

Being on the Endangered Species list allowed protection of the terns' habitat, and allowed the natural rebound and growth of the colonies. Colonies at Mission Bay are either fenced or reachable only by watercraft. In a multi- agency effort that includes the City of San Diego Park and Recreation Department, the U.S. Department of Fish and Wildlife Service, the California Department of Fish and Game and the Wildlife Services Program of the U.S. Department of Agriculture, professionals from the wildlife program carry out the humane trapping of predators that are attracted to least tern nesting sites. This includes skunks and opossums, as well as feral cats and dogs, believed to be former pets who were abandoned by their owners.

The ibisbill belongs to the order Charadriiformes which also includes the sandpipers, plovers, terns, auks, gulls, skuas and others. Although its evolutionary relationships are not fully understood, the ibisbill appears to be most closely related to a group including the oystercatchers, avocets, stilts and Pluvialis plovers, but sufficiently distinctive to merit its own family, Ibidorhynchidae. River Kosi, outskirts of Jim Corbett National Park, India There are no subspecies. The species was described in 1831 by Vigors based on painting by John Gould although Brian Hodgson had sent a manuscript to the Asiatic Society of Bengal two years earlier describing it as the "Red-billed Erolia" but this was published only in 1835 with an apology from the editor.

Two skuas and a giant petrel fighting over a dead Antarctic fur seal Outside the breeding season, skuas take fish, offal, and carrion. Many practice kleptoparasitism, which comprises up to 95% of the feeding methods of wintering skuas, by chasing gulls, terns and other seabirds to steal their catches, regardless of the size of the species attacked (up to three times heavier than the attacking skua). The larger species, such as the great skua, also regularly kill and eat adult birds, such as puffins and gulls, and have been seen killing birds as large as a grey heron.Scottish Ornithologists' Club On the breeding grounds, the three, more slender northern breeding species commonly eat lemmings.

The 580,000 hectare large delta is home to massive amounts of water birds of all kinds, most notably pelicans of two species, herons, storks, cormorants and terns. It is a favourite staging area for passage migrants and also wintering grounds for masses of migrating water birds from the steppes, the boreal forests and the tundras further north. The region has some of Europe's very few remaining grazed mosaique forest landscapes, kept in their natural state by the wild horses and wild cattle still present. Working with partners, the Rewilding Danube Delta team is working to significantly improve the ecological integrity and natural functioning of 40,000 hectares of wetland and terrestrial delta habitat, using rewilding principles on a landscape scale.

In November 2018 East Lothian Council granted planning permission for Scottish Power to improve the wildlife and amenity value of Levenhall Links. The plans are that Lagoon 8, the one closest to the River Esk, will be landscaped to create a large wetland area with islands to be used as roosting areas for waders, gulls and terns, this will be protected by a moat and overlooked by paths and accessible bird hides. Lagoon 6, at the eastern end of the site, will be differently modified by infilling to create a natural habitat for birds and insects. There are also plans to regrade the surface at Lagoon 7, between Lagoon 8 and the boating pond, to make gentler slopes.

The greater crested tern Retrieved 28 February 2012 (Thalasseus bergii), also called crested tern or swift tern, is a tern in the family Laridae that nests in dense colonies on coastlines and islands in the tropical and subtropical Old World. Its five subspecies breed in the area from South Africa around the Indian Ocean to the central Pacific and Australia, all populations dispersing widely from the breeding range after nesting. This large tern is closely related to the royal and lesser crested terns, but can be distinguished by its size and bill colour. The greater crested tern has grey upperparts, white underparts, a yellow bill, and a shaggy black crest that recedes in winter.

Sooty terns are the most abundant breeding seabirds and are common along the east coast. A total of 202 different birds have been recorded on the island. Eighteen species of land birds breed on the island and many more migratory species occur on the island and its adjacent islets, many tame enough that humans can get quite close. The island has been identified by BirdLife International as an endemic bird area, and the Permanent Park Preserve as an important bird area, because it supports the entire population of Lord Howe woodhens, most of the breeding population of providence petrels, over 1% of the world population of another five seabird species, and the whole populations of three endemic subspecies.

The lagoon's importance for migratory birds means that it is a site which is subject to the Ramsar Convention for the conservation and sustainable use of wetlands. On the land the fynbos surrounding the lagoon is home to southern black korhaan, Cape spurfowl and grey-winged francolin, Cape penduline and grey tit, southern anteater chat, white-throated and yellow canary, Karoo lark, chestnut-vented warbler, bokmakierie and Cape bunting, which are all easily seen. African marsh harrier and black Harrier hunt by quartering the ground. The coastal islands at the mouth of the lagoon are important breeding colonies for Cape and Hartlaub's gull, Cape gannet and African penguin, as well as cormorants and terns.

1:2ll‑233 Denham reported that in July 1863 the islets had only two or three plants, including a bush high, and were frequented by sea turtles weighing . On 12 October 1858, Denham reported that Cato Island was more substantial than other cays in the area, measuring , rising to , and covered in coarse tufted grass, Rottboilla; a creeping plant, Nyctagin portulaca; and a sort of buttercup Senebiera crucifera, undermined and fertilised by burrowing mutton birds, the only species that the sailors chose to eat. Dense colonies of gannets, man-of-war birds and boatswain birds, terns and noddies, with eggs and chicks were abundant. Denham shot a godwit and a brace of plovers.

Adult three-toed box turtles (Terrapene carolina triunguis), Houston toad (Anaxyrus houstonensis) juveniles, and American alligator (Alligator mississippiensis) hatchlings are also attacked and killed by these ants. Despite this mostly-negative association, one study shows that red imported fire ants may be capable of impacting vector-borne disease transmissions by regulating tick populations and altering vector and host dynamics, thereby reducing transmission rates not only to animals, but to humans as well. Mortality rates have been well observed in birds; there have been instances where no young have survived to adulthood in areas with high fire ant density. Many birds including cliff nesting swallows, ducks, egrets, quail, and terns have been affected by red imported fire ants.
