Erebine caterpillars feed on a broad range of plants; many species feed on grasses and legumes, and a few are pests of castor bean, sugarcane, rice, as well as pistachios and blackberries.

The next month, without explicitly naming Boeing as the aircraft originator, the Army cited the Pelican as an emerging technology to improve strategic responsiveness in its 2002 Transformation Roadmap. In July, a U.S. Transportation Command team lead at Scott Air Force Base mentioned the Pelican as a practical solution for moving troops and equipment over long distances. Meanwhile, the designers evaluated three different aircraft sizes with mean takeoff weights of and wingspans of , respectively.

Titanoptera is an extinct order of neopteran insects from the Triassic period. Titanopterans were very large in comparison with modern insects, some having wingspans of up to . They were related to modern grasshoppers, but were much larger, had proportionally weaker hindlegs that could not allow the animals to leap, and grasping forelegs and elongated mandibles. Another distinctive feature was the presence of prominent fluted regions on the forewings, which may have been used in stridulation.

They are medium to very large moths, with adult wingspans ranging from 7.5 to 15 cm, in some cases even more. They consist of some of the largest groups of Lepidoptera like the moon or luna moth, atlas moth, and many more. The Saturniinae is an important source of wild silk and human food in many different cultures. The saturniine genera, approximately 169 in number, are divided into four major and one minor (Micragonini) tribes.

Meganeura is a genus of extinct insects from the Carboniferous period (approximately 300 million years ago), which resembled and are related to the present-day dragonflies. With wingspans ranging from to over , M. monyi is one of the largest-known flying insect species. Meganeura were predatory, with their diet mainly consisting of other insects. Wing venation of Meganeura monyi, redrawn after Brongniart (1893, Pl. XLI) Fossils were discovered in the French Stephanian Coal Measures of Commentry in 1880.

It is considered a medium-sized megabat, with adults weighing and possessing wingspans of approximately . Individuals are dark brown or grayish brown, with their undersides paler than their backs. The Egyptian fruit bat is a highly social species, usually living in colonies with thousands of other bats. It, along with other members of the genus Rousettus, are some of the only fruit bats to use echolocation, though a more primitive version than used by bats in other families.

Dragonfly anatomy The imago (adult stage) has a large head, well-developed, compound eyes, legs that facilitate catching prey (largely other insects) in flight, two pairs of long, transparent wings that move independently, and an elongated abdomen. Many Odonata are relatively large insects, but wingspans range from 17 mm (some Agriocnemis damselflies) to 191 mm (helicopter damselfly Megaloprepus coerulatus. The largest dragonflies have a wingspan of up to 160 mm, but they are much more massive than any damselfly.

Melaleucas grow on average in the Everglades, as opposed to in their native Australia. They were brought to southern Florida as windbreaks and deliberately seeded in marsh areas because they absorb vast amounts of water. In a region that is regularly shaped by fire, melaleucas are fire-resistant and their seeds are more efficiently spread by fire. They are too dense for wading birds with large wingspans to nest in, and they choke out native vegetation.

Various tribes were considered within the proposition, with most differentiation coming from genital structure. In the modern, reduced description, the Elachistidae are small to very small moths (wingspans usually around 1 cm). Their wings appear feather-like due to the fine hair covering the wings' fringes, and the hindwings can be significantly reduced in area, essentially consisting of a small strip with a wide hairy fringe. The caterpillars are typically leaf miners or stem miners on Poales.

The Calpinae are a subfamily of moths in the family Erebidae described by Jean Baptiste Boisduval in 1840. This subfamily includes many species of moths that have a pointed and barbed proboscis adapted to piercing the skins of fruit to feed on juice, and in the case of the several Calyptra species of vampire moths, to piercing the skins of mammals to feed on blood. The subfamily contains some large moths with wingspans longer than 5 cm (2 in).

In most insects, air is taken in through openings on the sides of the abdomen and thorax called spiracles. The respiratory system is an important factor that limits the size of insects. As insects get larger, this type of oxygen transport is less efficient and thus the heaviest insect currently weighs less than 100 g. However, with increased atmospheric oxygen levels, as were present in the late Paleozoic, larger insects were possible, such as dragonflies with wingspans of more than two feet.

Adult males have androconial scales on the subcostal region of their hindwings and on their median membrane. Adult wingspans range from about 6.7 to 8.0 cm. Adults have a variety of phenotypes, all with red coloration. These include: dennis-ray pattern ("dennis" refers to a red patch on the forewing; "ray" refers to red lines on the hindwing); red on the forewing with yellow on the hindwing; yellow on the forewing and red on the hindwing; and white or yellow on the hindwing and forewing.

Colour brighter, the contrast between the green of the upper and the blue of the lower portion of the medial band more vivid. Hindwing more produced posteriorly at apex of vein 3, where it forms an elongate tooth or short tail. Variously reported with wingspans between 55 and 75 mm, the common bluebottle has black upper wings and brown lower wings. Both forewings and hindwings are marked by a central spot in the form of a blue or blue-green triangle, with apex pointing toward the body.

These are one of the two largest extant Old World vultures and accipitrids, with similar total length and perhaps wingspans recorded in the Himalayan vulture (Gyps himalayensis) , as indicated by broadly similar wing and tail proportions, but the cinereous appears to be slightly heavier as well as slightly larger in tarsus and bill length.Mohapatra, R. K., Sahu, S. K., Panda, S., Das, J. K., & Upadhyay, H. S. (2019). Himalayan Griffon: rescue and treatment of Gyps himalayensis in Odisha, India. ZOO'S PRINT, 34(3), 24-27.

Average wingspans are not known for the Steller's species, however white-tailed eagles do appear to outsize the average wingspan of the wedge-tailed eagle (Aquila audax), which is sometimes also titled the largest winged extant eagle (however one wedge- tail did possess the largest wingspan ever verified for an extant eagle). In one sample from Norway, 5 male white-tailed eagle were found to average and 8 females were found to average .Willgohs, J. F. (1961). The white-tailed eagle Haliaëtus albicilla albicilla (Linné) in Norway.

The merlin (Falco columbarius) is a small species of falcon from the Northern Hemisphere, with numerous subspecies throughout North America and Eurasia. A bird of prey once known colloquially as a pigeon hawk in North America, the merlin breeds in the northern Holarctic; some migrate to subtropical and northern tropical regions in winter. Males typically have wingspans of , with females being slightly larger. They are swift fliers and skilled hunters who specialize in preying on small birds in the size range of sparrows to quail.

Meganisoptera is an extinct order of very large to gigantic insects, occasionally called griffinflies. The order was formerly named Protodonata, the "proto-Odonata", for their similar appearance and supposed relation to modern Odonata (damselflies and dragonflies). They range in Palaeozoic (Late Carboniferous to Late Permian) times. Though most were only slightly larger than modern dragonflies, the order includes the largest known insect species, such as the late Carboniferous Meganeura monyi, Megatypus, and the even larger early Permian Meganeuropsis permiana, with wingspans of up to .

"Postcranial skeletal pneumaticity and air-sacs in the earliest pterosaurs." Biology Letters, 5(4): 557–560. ). Unlike their descendants the pterodactyloids, most rhamphorhynchoids had teeth and long tails, and most species lacked a bony crest, though several are known to have crests formed from soft tissue like keratin. They were generally small, with wingspans rarely exceeding 2.5 meters, though one species alluded to by Alexander Stoyanow might be among the largest pterosaurs of all time with a wingspan of 10 meters, comparable to the largest azhdarchids.

The hammer-headed bat ('), also known as hammer-headed fruit bat and big- lipped bat, is a megabat widely distributed in West and Central Africa. It is the only member of the genus Hypsignathus, which is part of the tribe Epomophorini along with four other genera. It is the largest bat in continental Africa, with wingspans approaching 1 m, or about 3 ft, and males almost twice as heavy as females. Males and females also greatly differ in appearance, making it the most sexually dimorphic bat species in the world.

A female specimen collected in 1979 had a wingspan of , but Tindale recorded female wingspans at in 1932. The forewings of both males and females feature silvery-white bars, although the bars of the male moth's wings are more prominent and with dark margins. The female's body colour is usually a darker brown than the male's pale brown, as noted by Tindale, although a grey-brown female was collected in 1979. Hepialidae have short, pectinate antennae and, unusually primitive for Lepidoptera, lack a functional proboscis or retinaculum and are therefore non-feeding.

This is hypothesized as a response to a lack of diurnal avian (day-active bird) predators on the island. They have especially small and rounded wingtips, low wing loading (meaning they lave large wings relative to body mass), and high camber. These factors give them increased agility, and they are capable of making quick, tight turns at slow speeds. Relative to all bats, horseshoe bat wingspans are typical for their body sizes, and their aspect ratios, which relate wingspan to wing area, are average or lower than average.

Skeleton of American crow (Corvus brachyrhynchos) on display at the Museum of Osteology Corvids are large to very large passerines with a robust build, strong legs and all species except the pinyon jay have nostrils covered by bristle-like feathers. Many corvids of temperate zones have mainly black or blue coloured plumage; however, some are pied black and white, some have a blue-purple iridescence and many tropical species are brightly coloured. The sexes are very similar in color and size. Corvids have strong, stout bills and large wingspans.

The skipper introduces themself, and begins to take the boat full of guests down the tropical rivers of the world. The ride starts out in the Amazon River, where the passengers encounter butterflies with one-foot wingspans, or as the skipper might say, twelve inches. The boat then passes Inspiration Falls, which transitions into the Congo River in Africa. The skipper explains that there is a pygmy welcoming party waiting for them, but when the boat arrives at the beach, the canoes are empty, and the place deserted.

The wingspans of females are slightly larger than males, females having a wingspan of 23 mm and males 20 mm. Common grass blues have a weak, fluttering flight and so usually fly near ground level close to a food source. Eggs are white or pale blue and have a mandarin shape with a pitted surface. Caterpillars reach about 7 mm in length, and their appearance is primarily green with a yellow stripe at the sides and a darker green stripe on the back, and brown or black head usually obscured under the thorax.

The type specimen of Samrukia was at first believed to belong to an oviraptorosaurian theropod dinosaur. An initial cladistic analysis by Naish et al. found Samrukia nessovi instead to be a basal member of the bird lineage Ornithuromorpha. They interpreted Samrukia as a very large bird (the jawbone is twice as long as that of an ostrich), but noted that it is not known whether Samrukia would have been able to fly (in which case they would have had wingspans of roughly ) or not (in which case they would have been around tall).

Niphopyralis chionesis, adult Pseudebulea fentoni, adult male Adult Wurthiini are small to medium-sized moths with wing spans of normally 20 to over 30 mm, whereas adults of Niphopyralis are usually somewhat smaller, with wingspans of 12 to 22 mm, and the males being smaller than the females. In the male genitalia, the uncus consists of a single head bearing stiff chaetae, or it is bicapitate (Niphopyralis). The tegumen-vinculum complex is more or less elongate rounded. The valvae are slender and tapering towards the apex, with the costa weakly to strongly concave (e.g.

Initially, Crane considered stone to construct the building but later decided on cream-colored terracotta despite concerns its blocks would be small and prone to warping. It featured a large number of figures situated and higher along the building facade and around its pinnacle, including eagles with wingspans up to , giants and angels up to . Some of these were later removed after concerns about falling materials and to obtain unobstructed penthouse views. An octagonal bartizan was designed at the top of the building with long, narrow loop windows, and it was topped by a dome with heraldic imagery.

The ones that look like males, andromorphs, are usually under a third of the female population but the proportion can rise significantly and a theory that explains this response suggests that it helps overcome harassment by males. Some Coenagrionid damselflies show male-limited polymorphism, an even less understood phenomenon. In general, damselflies are smaller than dragonflies, the smallest being members of the genus Agriocnemis (wisps). However, members of the Pseudostigmatidae (helicopter damselflies or forest giants) are exceptionally large for the group, with wingspans as much as in Megaloprepus and body length up to in Pseudostigma aberrans.

Juvenile plumage First immature plumage The buff-sided robin is a medium- to large-sized robin species, with body length ranging from . Adult buff-sided robins are not sexually dimorphic, and the sexes cannot be differentiated on the basis of plumage. However, males are generally larger than females with very little overlap for weight, head length, bill length, tarsus and wing cord length; and sexing criteria can be developed on the basis of combined morphological measurements. Based on data from museum specimen labels, adult wingspans range from (n=22) in male birds to in female birds (n=17).

Pteranodon (; from Greek πτερόν (pteron, "wing") and ἀνόδων (anodon, "toothless")) is a genus of pterosaur that included some of the largest known flying reptiles, with wingspans over 7 meters (23 feet). They lived during the late Cretaceous geological period of North America in present-day Kansas, Alabama, Nebraska, Wyoming, and South Dakota. More fossil specimens of Pteranodon have been found than any other pterosaur, with about 1,200 specimens known to science, many of them well preserved with nearly complete skulls and articulated skeletons. It was an important part of the animal community in the Western Interior Seaway.

Illustration of a pair by John Gerrard Keulemans, 1888 The Sind sparrow is very similar to the house sparrow, and both sexes resemble their counterparts of that species, but it is slightly smaller and males and females each have features that distinguish them as Sind sparrows. The Sind sparrow is long, while the common South Asian subspecies of the house sparrow, Passer domesticus indicus, is long. Wingspans range from , tails from , and tarsi measure . The breeding male has a short and narrow black bib and a broad chestnut eye stripe that does not meet the mantle.

Polemaetus bellicosus- University of Michigan Species Profile Average wingspans have been claimed of and for the species, however ten measured martial eagles in the wild were found to average in wingspan. Thus, the martial eagle appears to average fourth in wingspan among living eagles, behind only the Steller's sea-eagle (Haliaeetus pelagicus), the white-tailed eagle (Haliaeetus albicilla) and the wedge-tailed eagle (Aquila audax), in roughly that order.Mendelsohn, J.M., Kemp, A.C., Biggs, H.C., Biggs, R., & Brown, C.J. (1989). Wing areas, wing loadings and wing spans of 66 species of African raptors. Ostrich, 60(1), 35-42.

Sciota uvinella, larva found on sweetgum The Pyralidae, commonly called pyralid moths, snout moths or grass moths, are a family of Lepidoptera in the ditrysian superfamily Pyraloidea. In many (particularly older) classifications, the grass moths (Crambidae) are included in the Pyralidae as a subfamily, making the combined group one of the largest families in the Lepidoptera. The latest review by Eugene G. Munroe and Maria Alma Solis, in Kristensen (1999) retains the Crambidae as a full family of Pyraloidea. The wingspans for small and medium-sized species are usually between 9 and 37 mm with variable morphological features.

A cage for a tame pet bird which is allowed out daily should be large enough to allow it to easily extend its wings fully without hitting cage sides or toys or objects within the cage. In some countries, it is illegal to house a pet bird in a cage that does not permit it to spread its wings. Wingspans of common pet birds range from approximately for a budgie and for a cockatiel up to as much as for the larger macaws. Rectangular cages have replaced rounded cages due to the damaged wings caused by non bird friendly round cages.

Size of Istiodactylus latidens compared to a human Ornithocheiromorphs were large pterosaurs, with wingspans normally ranging between . Istiodactylus for example, had a wingspan ranging from , with the most complete known skull estimated to have been about in length, based on a long-lost fragment of its jaw reported in 2012. Though its jaws measured only , which was less than 80 percent of the skull's length. Ornithocheirids were typically larger than others of the group and were more successful within the food chain rather than other ornithocheiromorphs, one reason is because of their large size, Ornithocheirus itself had a wingspan measuring .

Most large azhdarchids probably fed on small prey, including hatchling and small dinosaurs; in an unusual modification of the azhdarchid bauplan, the unusually robust Hatzegopteryx may have tackled larger prey as the apex predator in its ecosystem. In another departure from typical azhdarchid lifestyles, the jaw of Alanqa may possibly be an adaptation to crushing shellfish and other hard foodstuffs. Azhdarchids are generally medium- to large-sized pterosaurs, with the largest achieving wingspans of , but several small-sized species have recently been discovered. Another azhdarchid that is currently unnamed, recently discovered in Transylvania, may be the largest representative of the family thus far discovered.

Helios Prototype flying wing moments after takeoff, beginning its first test flight on solar power from the U.S. Navy's Pacific Missile Range Facility on Kauai, Hawaii, July 14, 2001. The Helios Prototype is an ultra-lightweight flying wing aircraft with a wingspan of , longer than the wingspans of the U.S. Air Force C-5 military transport ( or the Boeing 747 (, depending on the model), the two largest operational aircraft built in the United States. The electrically powered Helios is constructed mostly of composite materials such as carbon fiber, graphite epoxy, Kevlar, Styrofoam, and a thin, transparent plastic skin. The main tubular wing spar is made of carbon fiber.

Containing many of the primitive features of the time: very long cerci, an ovipositor, and wings with little or no anal lobe. Protodonata, as its name implies, is a primitive paraphyletic group similar to Odonata; although lacks distinct features such as a nodus, a pterostigma and an arculus. Most were only slightly larger than modern dragonflies, but the group does include the largest known insects, such as the late Carboniferous Meganeura monyi, Megatypus, and the even larger later Permian Meganeuropsis permiana, with wingspans of up to . They were probably the top predators for some 100 million years and far larger than any present-day insects.

The airport's service area includes the cities of Lake Wales, Dundee, Eagle Lake, Fort Meade, Frostproof, Highland Park, Hillcrest Heights, and Lake Hamilton. Typical operations conducted at the airport are local and transient general aviation, localized recreational glider activity, and skydiving. Presently there are no air carrier, commuter or air taxi operations conducted at the airport. The airport's current role and classification are listed in the FAA's National Plan of Integrated Airport System (NPIAS) as a General Utility General Aviation Airport capable of accommodating virtually all general aviation aircraft with maximum gross takeoff weights of 12,500 pounds or less with wingspans up to, but not including, 79 feet.

The respiratory system had efficient unidirectional "flow-through" breathing using air sacs, which hollowed out their bones to an extreme extent. Pterosaurs spanned a wide range of adult sizes, from the very small anurognathids to the largest known flying creatures of all time, including Quetzalcoatlus and Hatzegopteryx, which reached wingspans of at least nine metres. The combination of endothermy, a good oxygen supply and strong muscles made pterosaurs powerful and capable flyers. Pterosaurs are often referred to by popular media or the general public as "flying dinosaurs", but dinosaurs are defined as the descendants of the last common ancestor of the Saurischia and Ornithischia, which excludes the pterosaurs.

The hindlimbs of ornithocheiromorphs were strongly built, yet relative to their wingspans, smaller than those of birds in terms of hindlimb- to-wingspan ratio. The hindlimbs were long in comparison to the torso length, and the thighbone was rather straight, with the head making only a small angle with the shaft. This implied the legs not being held vertically below the body, but were somewhat sprawling within. A tibiotarsus is mostly seen in many ornithocheiromorphs, this consisted on the shinbone (tibia) being fused with the upper ankle bones, resulting in a longer structure than the thighbone, which could attain a vertical position when walking.

For bat embryos, apoptosis (cell death) affects only the hindlimbs, while the forelimbs retain webbing between the digits that forms into the wing membranes. Unlike birds, whose stiff wings deliver bending and torsional stress to the shoulders, bats have a flexible wing membrane that can resist only tension. To achieve flight, a bat exerts force inwards at the points where the membrane meets the skeleton, so that an opposing force balances it on the wing edges perpendicular to the wing surface. This adaptation does not permit bats to reduce their wingspans, unlike birds, which can partly fold their wings in flight, radically reducing the wing span and area for the upstroke and for gliding.

Artist's impression of a crested specimen Nyctosaurus, like its relative Pteranodon, appears to have grown very rapidly after hatching. Fully adult specimens are no larger than some immature specimens such as P 25026 (pictured below), indicating that Nyctosaurus went from hatching to adult size (with wingspans of or more) in under a year. Some sub-adult specimens have been preserved with their skulls in nearly pristine condition, and lack any trace of a head crest, indicating that the distinctively large crest only began to develop after the first year of life. The crest may have continued to grow more elaborate as the animal aged, though no studies have examined the age of the fully adult, large- crested specimens.

Contrasting yellow mantle of the Mariana fruit bat (Pteropus mariannus) Megabats are so called for their larger weight and size; the largest, the great flying fox (Pteropus neohibernicus) weighs up to , Two subspecies are recognized: with wingspans reaching up to . Despite the fact that body size was a defining characteristic that Dobson used to separate microbats and megabats, not all species of megabat are larger than microbats; the spotted-winged fruit bat (Balionycteris maculata), a megabat, weighs only . The flying foxes of Pteropus and Acerodon are often taken as exemplars of the whole family in terms of body size. In reality, these genera are outliers, creating a misconception of the true size of most megabat species.

Pterosaurs were the next to evolve flight, approximately 228 million years ago. These reptiles were close relatives of the dinosaurs (and sometimes mistakenly considered dinosaurs by laymen), and reached enormous sizes, with some of the last forms being the largest flying animals ever to inhabit the Earth, having wingspans of over 9.1 m (30 ft). However, they spanned a large range of sizes, down to a 250 mm (10 in) wingspan in Nemicolopterus. Birds have an extensive fossil record, along with many forms documenting both their evolution from small theropod dinosaurs and the numerous bird-like forms of theropod which did not survive the mass extinction at the end of the Cretaceous.

The Andean condor (Vultur gryphus) is a South American bird in the New World vulture family Cathartidae and is the only member of the genus Vultur. Found in the Andes mountains and adjacent Pacific coasts of western South America, the Andean condor is the largest flying bird in the world by combined measurement of weight and wingspan. It has a maximum wingspan of exceeded only by the wingspans of four water birds—the roughly maximum of the wandering albatross, southern royal albatross, great white pelican and Dalmatian pelican. It is a large black vulture with a ruff of white feathers surrounding the base of the neck and, especially in the male, large white patches on the wings.

The Dalmatian pelican (Pelecanus crispus) is the largest member of the pelican family, and perhaps the world's largest freshwater bird, although rivaled in weight and length by the largest swans. They are elegant soaring birds, with wingspans that rival that of the great albatrosses, and their flocks fly in graceful synchrony. With a range spanning across much of Central Eurasia, from the Mediterranean in the West to the Taiwan Strait in the East, and from the Persian Gulf in the South to Siberia in the North, it is a short-to-medium- distance migrant between breeding and overwintering areas. No subspecies are known to exist over its wide range, but based on size differences, a Pleistocene paleosubspecies, P. c.

Many of them eat the abundant krill (which in turn feed on phytoplankton and ice-algae). Humpback whales are shown catching krill through sophisticated co-operation: they create spiralling curtains of air bubbles that drive it into their centre, where the whales can then catch them by surging upwards in the middle of the spiral. Also shown are the various seabirds which feed in the Antarctic sea, especially albatrosses, whose impressive wingspans are possible because they utilise the updraft generated by the huge waves in the stormy southern waters. Because of the patchiness of krill, albatrosses can travel for many hundreds or indeed thousands of miles on a single trip in search of it.

The seabird in question was the genus Sula, with their common name being boobies. These birds have large flat feet and wide wingspans for marine habitats but are clumsy and slow on shore making them easy to catch. The birds are also known for landing aboard seagoing vessels, whereupon they have been eaten by the crew. The phrase booby trap originally applied to schoolboy pranks, but took on its more sinister connotation during World War I. The term "booby trap" gives rise to the idea that an individual with the misfortune to be caught in the trap does so because the individual is a "booby", or that an individual who is caught in the trap thereby becomes a "booby".

Most of the common names refer to these birds' most notable trait: tooth-like points on their beak's edges, which, unlike true teeth, contained Volkmann's canals and were outgrowths of the premaxillary and mandibular bones. Even "small" species of pseudotooth birds were the size of albatrosses; the largest ones had wingspans estimated at 5–6 metres (15–20 ft) and were among the largest flying birds ever to live. They were the dominant seabirds of most oceans throughout most of the Cenozoic, and modern humans apparently missed encountering them only by a tiny measure of evolutionary time: the last known pelagornithids were contemporaries of Homo habilis and the beginning of the history of technology.Hopson (1964), Olson (1985: pp.

The trumpeters are now so plentiful that efforts are being undertaken to help them reestablish historical migratory routes to areas further south in the Rocky Mountains and the Great Basin region. The elegant trumpeter swan is North America's largest waterfowl, with a wingspans of 8 feet (2.6 m) and they can weigh up to 30 pounds (13 kg). Whooping cranes The altitude of the refuge ranges from 6,600 feet (2,000 m) to almost 10,000 feet (3,000 m) and consists of 65,810.25 acres (266.32 km2)USFWS Lands Report, 30 September 2007 of high altitude prairie and forested uplands. The lakes and cold water marshlands provide a relatively uncommon wetland environment favored by certain waterfowl and predatory birds such as the bald eagle and peregrine falcon.

But given the fragmented state of these, it is not at all clear whether the genus was restricted to the North Atlantic (and perhaps the adjacent Paratethys) or occurred also in the Pacific and in the Southern Hemisphere, where fossils of a similar size were found (see below).Mayr (2008), Clouter [2009ab] This genus belongs to the group of huge pseudotooth birds, with wingspans in excess of , and probably as much as . The complete head and bill probably measured almost in life, the eye socket had a diameter of and the humerus at its distal end was about wide. The well-preserved skull fossil shows deep grooves along the underside of the upper bill, with pits to accommodate the lower bill's "teeth".

The Ornithocheiromorpha was defined in 2014 by Andres and colleagues, and they made Ornithocheiromorpha the most inclusive clade containing Ornithocheirus, but not Pteranodon. Ornithocheiromorphs are considered to be some of the largest animals to have ever flown. Members of this group are also regarded to have some of the largest pterosaur wingspans, such as the one estimated for the huge Tropeognathus, though still not as large as those estimated for the azhdarchids, which may have reached up to . When ornithocheiromorphs first appeared, they were initially scavengers, consisting in a more terrestrial setting, but their success had made them the top predators of the skies, as well as the most common type of fish-eating pterosaur throughout the early Late Cretaceous.

The mounting was strengthened with two diagonal struts on each side, one from the base of the forward interplane strut to the upcurved tip of the lower member and the other from the rear interplane strut to the junction of the lower member and its first vertical cross member. Each of these lower members, which supported the aircraft on the ground as skids, carried twin, rubber sprung landing wheels. Behind the wing the upper and lower members converged to the rear; the drag on the lower members shortened the landing run. The wingspans of the Type E were greater than those of the Type C with an increase of the inner bay width which placed the booms further apart and increased the undercarriage track from , making landings easier.

While most specimens are found crushed, enough fossils exist to put together a detailed description of the animal. Size of P. longiceps male (green) and female (orange) compared with a human Methods used to estimate the mass of large male Pteranodon specimens (those with wingspans of about 7 meters) have been notoriously unreliable, producing a wide range of estimates from as low as to as high as . In a review of pterosaur size estimates published in 2010, researchers Mark Witton and Mike Habib demonstrated that the latter, largest estimates are almost certainly incorrect given the total volume of a Pteranodon body, and could only be correct if the animal "was principally aluminium". Witton and Habib considered the methods used by researchers who obtained smaller mass estimates equally flawed.

34–75 Phylogenetic evidence shows that there are at least three major lineages of barn owl, one in Europe, western Asia and Africa, one in southeastern Asia and Australasia, and one in the Americas, and some highly divergent taxa on islands. Accordingly, some authorities split the group into the western barn owl for the group in Europe, western Asia and Africa, the eastern barn owl for the group in southeastern Asia and Australasia, and the American barn owl for the group in the Americas. Some taxonomic authorities further split the group, recognising up to five species, and further research needs to be done to clarify the position. There is a considerable variation between the sizes and colour of the approximately 28 subspecies, but most are between in length, with wingspans ranging from .

William L. "Bill" Effinger Jr., founded Berkeley Models in a three-car garage in Brooklyn in 1933 to help support himself through engineering school. The following year he produced his company's first rubber-powered model-airplane kits, the Consolidated Fleetster and the Fokker triplane, and the year afterward introduced the first gas-powered model-airplane kit, the Buccaneer. The company, whose name came from the address of his family's home, 53 Berkeley Place, began advertising with classified ads in Universal Model Airplane News, initiating display ads in March 1934; by November 1935 he was advertising six kits in his "Master Models" series of scale-design kits with 20-inch wingspans. In 1936 came the Cavalier kit, with a nine-foot wingspan. Effinger made the company his full-time career upon graduating with a mechanical engineering degree from Brooklyn Polytechnic Institute in 1938. He went on to earn a degree in aeronautical engineering from the Massachusetts Institute of Technology, and in 1943 volunteered for the U.S. Navy.

Accipiter hawks usually ambush birds in dense vegetation, a dangerous hunting method that requires great agility. Many smaller tropical species of Accipiter eat nearly equal portions of insects and reptiles and amphibians as they do of birds while some of the larger species have become more generalized, and may feed extensively on rodents and lagomorphs as well as other various non-avian animals. Most accipitrids will supplement their diet with non-putrid carrion but, of course, none specialized with this as well as the 14-16 species of vultures, which have evolved very large bodies (which leave them equipped to fill their crop with carrion), weaker, less specialized feet relative to other accipitrids, large wingspans to spend extensively periods of time in flight over openings scanning for carcasses and complex social behavior in order to establish a mixed species hierarchy at carrion. The New World vultures have attained several similar characteristics, but only through convergent evolution and are seemingly not directly related to Old World vultures and other accipitrids.
