The summer fur is brown, with whitish underparts and tinged with yellowish or buffy brown. The tail has a black tip. In northern areas, the winter fur becomes white, sometimes with yellow tints, but the tail still have its black tip. The long-tailed weasel moults two times each year, once in autumn (October to mid-November) and once in spring (March–April). The bottom of the long-tailed weasel's feet has no fur in summer. Unlike skunks, which spray their musk, the long-tailed weasel drags and rubs its body over surfaces, to mark their territory and, when scared, to scare predators away.
