Widespread throughout Northwestern Ontario, in forested areas along streams, lakes and marshlands; also second-growth areas with mixed shrubs and grasses, and borders of fields and pasture land.
Primarily a carnivore, the mink’s diet consists mainly of small mammals, rodents, frogs, fish, crayfish, birds, eggs, insects and worms; some plant matter.
Because the mink dines heavily on fish and other water animal species, its population numbers in some areas been severely reduced by pollution. Trapping is no longer a major factor in the numbers of wild mink as most furs for the fashion industry come from commercial mink farms. In pristine habitats the mink does well; its numbers are stable and growing, only controlled by trapping.
A female will produce a litter of 2 to 10 offspring each year.
