Before the merge of the American hog-nosed skunks, the eastern hog-nosed skunk, Conepatus leuconotus is typically larger than the western hog-nosed skunk, Conepatus mesoleucus. Female eastern hog-nosed skunks range from 58 to 74 cm in length and 19–34 cm in height. They weigh between 2.0 and 4.0 kg. Male hog-nosed skunks range from 56 to 92 cm in length and 22–41 cm in height.

Humboldt's hog-nosed skunks are omnivorous, feeding primarily on insects but also on vertebrate prey, such as rodents and carrion during winters, when insects are less abundant. Patagonian hog nosed skunks have also been known to eat fruit Unlike other South American carnivorans, it is less effected by competition from increased dietary homogenization in areas where native prey species have gone extinct due to its largely strictly insectivorous diet.Palacios, R., Walker, R. S., & Novaro, A. J. (2012). Differences in diet and trophic interactions of Patagonian carnivores between areas with mostly native or exotic prey.

The hog-nosed skunks belong to the genus Conepatus and are members of the family Mephitidae (skunks). They are native to the Americas. They have white backs and tails and black underparts.Skunk. Columbia Electronic Encyclopedia, 6Th Edition [serial online].

There is high pressure from intraguild predation on Humboldt's hog- nosed skunks. It is often preyed upon and targeted competitively by larger carnivorans such as the culpeo, chilla fox, Geoffrey's cat, pampas cat, Andean cat, and puma. It, however, is unlikely to target other carnivorans.Oliveira, T. G., & Pereira, J. A. (2013).

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.

Humboldt's hog-nosed skunks are crepuscular, active primarily at dawn and twilight. It does little in the way of active hunting, selecting prey that is easiest to capture. During the winter seasons, it shifts from its open grassy habitats to shrubs, forests, and mountainous areas as insect populations decline to seek alternative food sources.

Its teeth are specialized for the consumption of invertebrates and fruit, their lower molars are adapted for crushing such resistant foods. Similar adaptation of the molars is seen in the South American gray fox. Like all South American hog-nosed skunks, it is smaller with a more primitive skull and tooth structure than North American skunks.Wang, X., & Carranza-Castañeda, Ó. (2008).

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.

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.

Native mammals that coexist with the Tehuantepec jackrabbit are the eastern cottontail (Sylvilagus floridanus), the nine-banded armadillo (Dasypus novemcinctus), the hooded and western hog-nosed skunks (Mephitis macroura, Conepatus mesoleucus), the Virginia opossum (Didelphis marsupialis), the gray mouse opossum (Tlacuatzin canescens), the gray fox (Urocyon cinereoargenteus), the common raccoon (Procyon lotor), and the coyote (Canis latrans). Of these, the gray fox and the coyote are native predators of the Tehuantepec jackrabbit.

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).

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.

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.

Other animals found in Toca da Boa Vista include another large atelid, Caipora bambuiorum, as well as Arctotherium brasiliensis, Catonyx cuvieri, Desmodus draculae, Nothrotherium maquinense, Protocyon troglodytes, Smilodon populator, giant anteaters, collared peccaries, crab-eating foxes and raccoons, striped hog-nosed skunks, and guanacoes. The environment inhabited by Protopithecus is unclear. Most of Brazil was thought to have been covered in open tropical cerrado vegetation during the Late Pleistocene, but if Protopithecus and Caipora were arboreal, their presence suggests that the region may have supported a dense closed forest during the Late Pleistocene. It is possible that the region alternated between dry open savannah and closed wet forest throughout the climate change of the Late Pleistocene.

The procyonids were followed to South America by rafting/island-hopping hog-nosed skunks and sigmodontine rodents. The oryzomyine tribe of sigmodontine rodents went on to colonize the Lesser Antilles to Anguilla. One group has proposed that a number of large Neartic herbivores actually reached South America as early as 9–10 Ma ago, in the late Miocene, via an early incomplete land bridge. These claims, based on fossils recovered from rivers in southwestern Peru, have been viewed with caution by other investigators, due to the lack of corroborating finds from other sites and the fact that almost all of the specimens in question have been collected as float in rivers without little to no stratigraphic control.

Where their range coincides with that of the common skunks, the local distribution of the two is practically the same. They live along the bottom-lands of watercourses, where vegetation is abundant and the supply of food most plentiful, or in canyons and on rocky mountain slopes. For their protection hog-nosed skunks create their own burrows, generally within a bank, or beneath a rock, or the roots of a tree, but do not hesitate to take possession of the deserted burrows of other animals, or of natural cavities among the rocks. Owing to their strictly nocturnal habits, they are generally much less frequently seen than the common skunks, even in localities where they are numerous.

Apparently, their main interest at these times is aerial play and display; they tend to ignore places where food is more plentiful or easily hunted in favor of simply soaring alone or in pairs in strong air currents. The food of this carnivore consists mainly of mid-sized mammals; the introduced European rabbit (Oryctolagus cuniculus) seems to have become a key prey item. The black-chested buzzard-eagle is helpful to farmers by keeping down the numbers of the rabbits, which can be serious agricultural pests. Among the native fauna degus (Octodon) and hog-nosed skunks (Conepatus) are important prey, but mammals as formidable as a gray fox (Urocyon cinereoargenteus) – two to over three times as heavy as the birds and certainly not defenceless – are occasionally hunted and killed by this hawk.
