Least Weasel
Mustela nivalis

Weasels
Weasels, Skunks & Allies (Mustelidae)

Measurement: Size: 15-20 cm Weight: 45 g

Description: This tiny weasel is dark above and light below. The tail is brown with only a hint of black at the tip. This lack of a distinct black tip helps to distinguish the least weasel from some of its larger cousins. In winter, it trades in its dark coat for a snow-white pelt. The colour change is the result of hairs losing their pigments, as opposed to growing a new coat like the snowshoe hare.

Range: This tiny weasel is regularly spotted in the northern part of the Canadian Rockies, from the Columbia Icefields north.

Diet: These tiny weasels use their diminutive size to invade the dens of small rodents. They will also feed on frogs, toads and insects.

Reproduction: Mating may take place several times per year. They do not exhibit the delayed implantation of other weasels, rather they give birth approximately 35 days after being impregnated. They may also produce several litters of 3 to 10 young per year.
