Red Wolf Brochure
U.S. Fish & Wildlife Service Endangered Red Wolves The U.S. Fish and Wildlife Service is reintroducing red wolves to prevent extinction of the species and to restore the ecosystems in which red wolves once occurred, as mandated by the Endangered Species Act of 1973. According to the Act, endangered and threatened species are of aesthetic, ecological, educational, historical, recreational, and scientific value to the nation and its people. On the Edge of Extinction The red wolf historically roamed as a top predator throughout the southeastern U.S. but today is one of the most endangered animals in the world. Aggressive predator control programs and clearing of forested habitat combined to cause impacts that brought the red wolf to the brink of extinction. By 1970, the entire population of red wolves was believed to be fewer than 100 animals confined to a small area of coastal Texas and Louisiana. In 1980, the red wolf was officially declared extinct in the wild, while only a small number of red wolves remained in captivity. During the 1970’s, the U.S. Fish and Wildlife Service established criteria which helped distinguish the red wolf species from other canids. From 1974 to 1980, the Service applied these criteria to find that only 17 red wolves were still living. Based on additional Greg Koch breeding studies, only 14 of these wolves were selected as founders to begin the red wolf captive breeding population. The captive breeding program is coordinated for the Service by the Point Defiance Zoo & Aquarium in Tacoma, Washington, with goals of conserving red wolf genetic diversity and providing red wolves for restoration to the wild. -

NOTES: 1 Animals listed in this Schedule, as a general rule, are described in the left hand column by reference to common or descriptive names and in the right hand column by reference to scientific names. But, in the event of any conflict as to the kind of animals that are listed, a scientific name in the right hand column prevails over the corresponding common or descriptive name in the left hand column. 2 Also included in this Schedule is any animal that is the hybrid offspring resulting from the crossing, whether before or after the commencement of this Schedule, of 2 animals at least one of which is or was an animal of a kind that is a controlled animal by virtue of this Schedule. 3 This Schedule excludes all wildlife animals, and therefore if a wildlife animal would, but for this Note, be included in this Schedule, it is hereby excluded from being a controlled animal.

Mink: Wildlife Notebook Series
Mink The American mink (Neovison vison) and other fur bearing animals attracted trappers, traders, and settlers to Alaska from around the world. Some of the most valuable furbearers belong to the Mustelidae or weasel family, which includes the American mink. Other members of this family in Alaska include weasels, martens, wolverines, river otters, and sea otters. Mink are found in every part of the state with the exceptions of Kodiak Island, Aleutian Islands, the offshore islands of the Bering Sea, and most of the Arctic Slope. General description: A mink's fur is in prime condition when guard hairs are thickest. Mink are then a chocolate brown with some irregular white patches on the chin, throat, and belly. White patches are usually larger on females and often occur on the abdomen in the area of the mammary glands. Several albino mink have been reported from Alaska. Underfur is usually thick and wavy, not longer than an inch. It is dark gray to light brown in color with some suggestion of light and dark bands. The tail is one third to one fourth of the body length with slightly longer guard hairs than the body. As an adaptation to their aquatic lifestyle, their feet have semiwebbed toes and oily guard hairs tend to waterproof the animal. Adult males range in total length from 19 to 29 inches (48-74 cm). They may weigh from three to almost five pounds (1.4-2.3 kg). Females are somewhat smaller than males. Their movements are rapid and erratic as if they are always ready to either flee or pounce on an unwary victim. -

American Mink Neovison Vison
American mink Neovison vison Mink are an important part of the native wilderness of North America, and are regularly spotted along the Chicago River. Like many larger predators, it is a species that needs space if it is to thrive and coexist with humans. The mink is a member of the Mustelid family (which includes weasels, otters, wolverines, martens, badgers and ferrets). Historically, two species of mink were found in North America; however, the sea mink is now extinct. It lived exclusively along the Atlantic coast and had adapted to this habitat because of the abundant food (it preferred eating Labrador duck). The sea mink was hunted to extinction in the late 19th century. The surviving species, the American mink, lives in a wide range of habitats and is found throughout the United States and Canada except for Hawaii and the desert southwest. The American mink has been introduced in Europe where it is considered to be a pest and tends to displace the smaller European mink. The American mink lives in forested areas that are near rivers, lakes and marshes. The mink is very territorial and males will fight other minks that invade their territory. They are not fussy over their choice of den, as long as it’s close to water. They sometimes nest in burrows dug previously by muskrats, badgers or skunks. The American mink is carnivorous, feeding on rodents, fish, crustaceans, amphibians and even birds. In its natural range, fish are the mink’s primary prey. Mink inhabiting sloughs and marshes primarily target frogs, tadpoles, and mice.
