Woody fencerows, odd areas, and abandoned farm buildings are also important habitat for eastern spotted skunks.

This skunk species also is a capable climber, although not as agile as the spotted skunks of the genus Spilogale.

Spotted skunks can live 10 years in captivity, but in the wild, about half the skunks die after 1 or 2 years.

Skunks store about 1 tablespoon (15 g) of the odorous oil and can quickly spray five times in row. It takes about one week to replenish the oil. The secretion of the spotted skunks differs from that of the striped skunks. The two major thiols of the striped skunks, (E)-2-butene-1-thiol and 3-methyl-1-butanethiol are the major components in the secretion of the spotted skunks along with a third thiol, 2-phenylethanethiol.

Common predators of blue- winged teal include humans, snakes, snapping turtles (Chlycha serpentina), dogs, cats, muskellunge, American crows (Corvus brachyrhnchos), magpies (Pica spp.), ground squirrels, coyotes (Canis latrans), red foxes (Vulpes fulva), gray foxes (Urocyon cinereoargenteus), raccoons (Procyon lotor), long-tailed weasels (Mustela frenata), American minks (Mustela vison), striped skunks (Mephitis mephitis), spotted skunks (Spilogale putorius), and American badgers (Taxidea taxus). During one study, about half of the nest failures of blue- winged teal were caused by mammals. Striped and Spotted Skunks were responsible for two-thirds of these losses. All nest losses caused by birds were attributed to either crows or magpies.

Western spotted skunks will attempt to build reserves of fat before winter. While they do not engage in true hibernation, they may sleep for several weeks during the winter.Genoways, H. H. (1984). Jones, J. K., Jr., D. M. Armstrong, R. S. Hoffmann, and C. Jones.

Footdrumming is used widely as a predator warning or defensive action. It is used primarily by fossorial or semi-fossorial rodents, but has also been recorded for spotted skunks (Spilogale putorius), deer (e.g. white-tailed deer Odocoileus virginianus), marsupials (e.g. tammar wallabies Macropus eugenii), rabbits (e.g.

Although both the spotted skunks and common skunks live mainly on insects, the hog- nosed skunks are even more insectivorous in their feeding habits. The bare snout appears to be used constantly for the purpose of rooting out beetles, beetle larvae (or grubs), and larvae of various insects from the ground.

Thioacetate derivatives of the three thiols are present in the spray of the striped skunks but not the spotted skunks. They are not as odoriferous as the thiols. Water hydrolysis converts them to the more potent thiols. This chemical conversion may be why pets that have been sprayed by skunks will have a faint "skunky" odor on damp evenings.

Up to eight skunks may share an underground den in the winter. They can also climb and take shelter in trees. Eastern spotted skunks seem to prefer forest edges and upland prairie grasslands, especially where rock outcrops and shrub clumps are present. In western counties, it relies heavily on riparian corridors where woody shrubs and woodland edges are present.

The eastern spotted skunk has seen sharp declines in populations from several states, particularly those in the Midwest, like Minnesota and Wisconsin for example. The exact reason behind the decrease in numbers is not known, which is puzzling considering the species was very quick to adapt to human settlement, and was commonly trapped up until the second half of the 20th century. Before then, they were frequently seen on farmlands, and were known to dig burrows under the sides of barns and prey on mice that were attracted to stored grains. In Minnesota, after a peak in the number of reported trapped specimen in 1949, during which over 19,400 spotted skunks were taken in that year alone, yearly reports of trapped spotted skunks in that state sharply fell in the following years.

Eastern spotted skunks usually breed in March or April and give birth in late May or early June. On average the female skunk gives birth to 4–5 baby skunks (kits) at a time. It takes twelve weeks before newborn skunks will become fully developed into adult skunks and two months before they develop skunk musk to use as self-defense.

Many species of animals reside within the preserve. Among them are hooded skunks, spotted skunks, hog-nosed skunks, stink badgers, coyotes, mule deer, javelina, raccoons, Gila monsters, ringtails, rock squirrels, spiny lizards, leopard frogs, Clark's spiny lizard, ornate tree lizard, Gilbert's skink, ring-necked snake, western diamondback rattlesnake, king snakes, gopher snakes, coral snakes, red racers, desert tortoise, gray fox, bobcats, and mountain lions.

The spotted skunks are the most similar to the weasels of the skunks. It has a slimmer body, and tail coat thinner smaller than their close relatives. It reaches a length of 115–345 mm with a tail of 70–120 mm. Its coat has a black background with white spots on the forehead and characteristics of 2-6 white stripes on the back and flanks.

Spotted skunks protect themselves by spraying a strong and unpleasant scent. Two glands on the sides of the anus release the odorous oil through nipples. When threatened, the skunk turns its body into a U-shape with the head and anus facing the attacker. Muscles around the nipples of the scent gland aim them, giving the skunk great accuracy on targets up to 15 feet away.

Reported predators of adult Great Basin Spadefoot toads include rattlesnakes, coyotes, and owls. Predators of larva include mud turtles (Kinosternon flavescens), spotted skunks (Spilogale putarius), raccoons (Procyon lotor), common crows (Corvus brachyrhynchos) and snakes. Adults are able to produce skin secretions that cause allergic reactions in some humans, including a burning sensation if the secretion gets in the eyes or nose. The skin secretions also deter predators.

The typical body length of eastern spotted skunks is with a tail length from , resulting in a total length of . The feet are long, and the forefeet have claws approximately long, while the hind feet have claws that are around . The feet are equipped with pads on the soles that aid in climbing. The large claws of the forefeet help the skunk dig and grasp prey.

Skunk species vary in size from about long and in weight from about (spotted skunks) to (hog-nosed skunks). They have moderately elongated bodies with relatively short, well-muscled legs and long front claws for digging. They have five toes on each foot. back left foot of an albino skunk Although the most common fur color is black and white, some skunks are brown or grey and a few are cream-colored.

Beavers cut willows, cottonwoods, and shrubs for food, and can significantly affect the riparian vegetation. Other rodents, such as antelope squirrels and pocket mice, are mostly omnivorous, using many different vegetation types. Grand Canyon bats typically roost in desert uplands, but forage on the abundance of insects along the river and its tributaries. In addition to bats, coyotes, ringtails, and spotted skunks are the most numerous riparian predators and prey on invertebrates, rodents, and reptiles.

Spilogale usually like to reside in covered thickets, woods, riparian hardwood, shrubbery, and areas that are located near streams. However, S. putorius usually enjoy staying in rocky and woody habitats that have copious amounts of vegetation. These sly creatures prefer to dwell in a den or natural cavities such as stumps or hollow logs. Spotted skunks have been found to adjust well to a wide array of dry prairie ecosystems in shallow dens.

Eastern spotted skunks are quite secretive and crafty creatures, and it is a rarity for humans to see them. They are also nocturnal and tend to be more active during dry cool nights rather than warm wet nights. Although these skunks do not hibernate, they do tend to greatly reduce their activity when enduring intensely warm summers or very cold winters. Generally speaking, out of the four species, S. putorius is the most active.

The animal has a conspicuously large, long- haired tail, measuring . The hair on the tail is mostly black, but is white at the tip, and sometimes also on the upper surface. The claws on the fore-feet are longer, and more curved, than those on the hind feet. As with other related species, western spotted skunks possess a pair of large musk glands that open just inside the anus, and which can spray their contents through muscular action.

Western spotted skunks are nocturnal omnivores, feeding on insects, small vertebrates, (such as mice, other rodents, rabbit kits, small birds, small reptiles and amphibians), roots, grains, fruit, and berries. Common insects eaten include beetles, grasshoppers, and caterpillars. However, they have been found to consume prey as large as the ashy storm petrel. They also feed on eggs and carrion.Mciver, W. R., Carter, H. R., Harvey, A. L., Mazurkiewicz, D. M., Howard, J. A., Martin, P. L., & Mason, J. W. (2018).

It is found in the Himalayas, including southern China, Nepal, Bhutan, India, and Pakistan. Fossil species of the family are also found in North America. Family Mephitidae (skunks and stink badgers) was once classified as mustelids, but are now recognized as a lineage in their own right. The 12 species of skunks are divided into four genera: Mephitis (hooded and striped skunks, two species), Spilogale (spotted skunks, four species), Mydaus (stink badgers, two species) and Conepatus (hog-nosed skunks, four species).

In the more rugged areas on the slopes of mountains and in the valley areas nearby, cougars, bobcats, marmots, rock squirrels, and bighorn sheep can occasionally be seen throughout this park. Other animals that can be found here include elk, mule deer, spotted skunks, shrews, ringtail cats, and ermine. ;Fish Stella Lake The Bonneville cutthroat trout is the only fish native to Great Basin National Park.

Mephitidae is a family of mammals comprising the skunks and stink badgers. They are noted for the great development of their anal scent glands, which they use to deter predators. There are twelve extant species of mephitids in four genera: Conepatus (hog-nosed skunks, four species); Mephitis (the hooded and striped skunks, two species); Mydaus (stink badgers, two species); and Spilogale (spotted skunks, four species). The two stink badgers in the genus Mydaus inhabit Indonesia and the Philippines; the other members of the family inhabit the Americas, ranging from Canada to central South America.

The fir-dominated forest around Lake of the Woods is home to numerous mammals, both large and small. The large mammals include mule deer, black-tailed deer, elks, black bears, coyotes, bobcats, and cougars. Some of the small mammals include porcupines, western spotted skunks, striped skunks, martens, minks, long-tailed weasels, snowshoe hares, yellow-bellied marmots, golden-mantled ground squirrels, Douglas squirrels, dusky-footed woodrats, bushy-tailed woodrats, creeping voles, deer mice, and northern pocket gophers."Mammals: Species List, Status, and Habitat" (PDF), Appendix F, Eastern Region Long-Range Forest Management Plan, Klamath- Lake District, Eastern Oregon Region, Oregon Department of Forestry, Klamath Falls, Oregon, October 1995.

Most mephitids are long, plus a tail, though the pygmy spotted skunk can be as small as 11 cm (4 in) plus a 7 cm (3 in) tail, and some striped skunks can be up to 82 cm (32 in) plus a 40 cm (16 in) tail. No estimates have been made for overall population sizes of any of the species, but two species are classified as vulnerable. Mephetids in general are not domesticated, though skunks are sometimes kept as pets. The twelve species of Mephitidae are split into four genera: the monotypic Conepatus, hog-nosed skunks; Mephitis, skunks; Mydaus, stink badgers; and Spilogale, spotted skunks.
