Adult American minks are almost entirely brown with a white chin and irregular white spots on the throat, chest, and belly. Males reach 27 inches long and 3 pounds, while females are smaller at up to 21 inches and 2 pounds. Unlike river otters, a mink's tail is not thick at the base or flat on the bottom. They have musk glands in the anal region that produce a strong odor.
Habitat & Range
Minks need permanent water and prefer woods nearby, dwelling along river and stream banks, shores of lakes and marshes, and farm ponds. They live under tree roots, in cavities in banks, under logs or stumps, in hollow trees, or in muskrat burrows and lodges.
Life History
Minks prey on mice, rabbits, fish, crayfish, and other animals, carrying food to a den to eat. Breeding begins in late February through early April, with gestation averaging 51 days; a single annual litter of 4โ5 young appears in early May, and the family stays together until late August.
Status, Trends & Threats
The species is described as uncommon in Missouri, with harvest regulated in accordance with the mink population density. Minks prey on small animals while also serving as prey for larger predators from great horned owls to coyotes.
