Mink

Mink are dark-coloured, semiaquatic, carnivorous mammals in the genera Mustela and Neogale and part of the family Mustelidae, which also includes weasels, stoats, martens, otters, badgers, and others. There are two main species referred to as "mink" today: the American mink and the European mink.

The fur of the American mink has been highly prized for use in clothing. Because of this, many American mink have been kept on fur farms, which has led to important discussions about animal rights and animal welfare. Some American mink have escaped from these farms or were released by activists, leading to feral populations in places like Europe and South America. In some countries, releasing mink into the wild is against the law.

American mink are sometimes seen as a threat to the European mink, which is a different species and less able to compete. Efforts to control American mink populations often involve trapping. Mink oil, made from these animals, is used in some medicines, cosmetics, and to treat and protect leather.

Species

The American mink (Neogale vison) is larger and more adaptable than the European mink (Mustela lutreola). You can usually tell them apart because all European mink have a large white patch on their upper lip, while only some American mink have this marking.

The sea mink (Neogale macrodon), which lived in the New England area, was a close relative of the American mink. It went extinct in the late 19th century mainly because people hunted them for their fur.

Description

A wild male mink weighs about 1 kg (2 lb 3 oz) and is about 60 cm (23 ½ in) long, while a female weighs about 600 g (1 lb 5 oz) and is about 50 cm (19 ½ in) long. These sizes do not include their tails, which can be from 12.8 to 22.8 cm (5 ⅛ to 9 in) long.

Mink have a rich, glossy brown coat that looks silky in the wild. Farm-bred mink come in many colors, from white to almost black. They usually have one litter per year with between six and 10 babies, though some farms have seen litters as large as 16.

Diet

Mink eat fish, other water animals, small mammals, birds, and eggs. Sometimes, adult mink will even eat young mink. Mink that live on farms are fed expired cheese, eggs, fish, meat and poultry leftovers, dog food, turkey livers, and special commercial food. A farm with 3,000 mink can need up to two tons of food each day.

Habitats

Mink enjoy living close to water, such as rivers, lakes, and marshes. They often follow streams and ditches, even when exploring. Although they usually stay near water, they sometimes wander a short distance away, especially when searching for food like rabbits. In places like Scotland and Iceland, mink can also be found along the coast. Occasionally, they live in towns if there is enough water nearby. Mink can be active at any time, even when people are around.

Territory

Mink are territorial animals. Male mink do not allow other males in their area, but they are less aggressive toward females. Usually, male and female territories are separate, but sometimes a female's area overlaps with a male's.

Their territories are long and narrow, often following river banks or the edges of lakes and marshes. These areas can be several miles long, with females having smaller territories than males. Each territory has one or two main spots where the mink spends most of its time, usually where there is plenty of food like fish or rabbits. The mink stays in these core areas for several days but also travels to the ends of its territory, likely to check for intruders and mark its area with scent.

Human uses

The fur of American mink has been valued for making clothing, leading to both hunting and farming of these animals. Today, the treatment of mink on fur farms is a big topic for animal rights and welfare groups. American mink have spread to places like Europe and South America after escaping from farms.

Mink can get infected with viruses, such as SARS-CoV-2, which can also spread to humans. This led some countries to ban or limit mink farming to protect public health. For example, Denmark killed all its mink to stop a special kind of virus from spreading.
