In the Sverdlovsk and Irkutsk Oblasts, mouse-like rodents are their most important foods, followed by birds, fish and insects. Although difficult to catch, the American mink, prior to being commercially farmed, was among the most frequently trapped furbearers as, unlike other furbearing mammals, it did not hibernate in winter, and could thus be caught on a nightly basis even in the far north. The secretions of the anal glands are composed of 2,2-dimethylthietane, 2-ethylthietane, cyclic disulfide, 3,3-dimethyl-1,2-dithiacyclopentane, and indole. The tail tip is black and the underfur is dark bluish-grey. Between 45 and 52 days is normal. [1] In Estonia, efforts have been made to re-establish viable populations on the islands of Saaremaa and Hiiumaa. [49], In Chile, American minks were introduced to Magallanes Region in the 1930s. [7], The European mink was historically hunted extensively, particularly in Russia, where in some districts, the decline prompted a temporary ban on mink hunting to let the population recover. Adult males measure 365–380 mm (14.4–15.0 in) in body length and have a tail length of 36–42 mm (1.4–1.7 in) (38% of its body length). ", "The impact of American mink, Mustela vison, as predators of native species in British freshwater systems", "Why is the European mink, Mustela lutreola disappearing? Because of their fondness for bathing, captive American minks may enter kettles or other open water-containing vessels. Although the true gestation period is 39 days, the embryo may stop developing for a variable period, so that as long as 76 days may elapse before the litter arrives. In its introduced range in Europe it has been classified as an invasive species linked to declines in European mink, Pyrenean desman, and water vole populations. A male mink will not tolerate another male within his territory, but appears to be less aggressive towards females. A very large subspecies, it is only slightly smaller than, A moderately-sized subspecies, it is slightly larger than, The middle zone of the European part of the.

[26] During swimming, the mink propels itself primarily through undulating movements of the trunk. Mink inhabiting the prairie sloughs primarily target frogs, tadpoles, and mice.

[21] It does not turn white in winter. [2] Despite having a similar name, build and behaviour, the European mink is not closely related to the American mink, being much closer to the European polecat and Siberian weasel (kolonok). As of 2005[update],[17] 15 subspecies are recognised. At birth, kits weigh about 6.5 grams (0.23 oz), and grow rapidly, trebling their weight 10 days after birth. [19] The American mink is similar in build to the European mink, but the tail is longer (constituting 38–51% of its body length).[20]. [5] In the Moscow Zoo, estrus was observed on 22–26 April, with copulation lasting from 15 minutes to an hour. In Finland, the main decline occurred in the 1920s-1950s and the species was thought to be extinct in the 1970s, though a few specimens were reported in the 1990s. Territory sizes vary, but they can be several miles long. The female weighs about 600 g (1.32 lb) and reaches a length of about 51 cm (20 in). A medium-sized subspecies, it has a pale russet to clay- or reddish-brown coat. Most territories are in undisturbed, rocky coastal habitats with broad littoral zones and dense cover. It is noted for its excellent bass fishing, and the area boasts more than 200 species of birds. « the water of this river possesses a peculiar whiteness, being about the colour of a cup of tea with the admixture of a tablespoonfull of milk.

Males measure 26 inches (66 cm) in body length and 9.4 inches (24 cm) in tail length.

The overall pelage is long, compact and silky.

glogeri (Matschie, 1912) They are born blind; the eyes open after 30–31 days. About 47% had escaped within two months, 31% had escaped prior to two months, and 21% "may or may not have been born in nature." [59], Because of numerous incidents of domestic mink escaping from fur farms and establishing themselves in the wild, concern has arisen among conservationists of the possible repercussions such escapes may have on natural wild mink populations. There are two extant species referred to as "mink": the American mink and the European mink. The Mink River's waters eventually flow into Gods Lake, and via the Gods River and the Hayes River into Hudson Bay. The length of the hairs on the back and belly differ little, a further adaptation to the European mink's semiaquatic way of life.
