Mustela vison (Schreber, 1777)

The American Mink, Mustela vison, is a North American member of the Mustelidae family found in Alaska, Canada and most of the United States. Some have established themselves in the wild in Newfoundland, Europe and South America after escaping from fur farms. In Europe, tens of thousand were intentionally introduced by the Soviet Union over a period of several decades, to provide a new game animal for trappers, with disastrous results. In later years, animal rights activists have also released several thousands in their attacks on fur farms. The larger American male will mate with European Mink females earlier in the spring than the males of the same species; the offspring are not born, but the females do not then breed again that season. This has contributed to the decline of the European species.

Their long slim body is covered in glossy, thick dark brown or black fur with a white patch under the chin. They have short legs with partially webbed feet, which make them excellent swimmers.

They can be found in wooded areas and fields near streams and lakes. They dig burrows in river banks or take over dens abandoned by other animals.

They feed on small mammals, fish, crayfish, frogs and other amphibians, also sometimes eating birds, insects and earthworms. These animals are mainly active at night and do not hibernate. Their predators include coyotes, the Great Horned Owl, red foxes and wolves. They are also trapped for their fur. Their numbers have been reduced due to loss of habitat and the effects of pollution on their aquatic food supply.

They are usually solitary animals. Mating occurs during winter; males and females may have more than one partner. Females give birth to 3 or 4 young during early spring.
