A Long-tailed Weasel (Mustela frenata), also called the Big Stoat or Bridled Weasel (for the "bridled" facial markings present in the summer months) on the hunt for some type of rodent. In Northern habitats, their dorsal fur turns white during the winter, while it is brown in summer. The tail has a distinct black tip. The long-tailed weasel moults twice annually, once in autumn (October to mid-November) and once in spring (March–April). Each moult takes about 3–4 weeks. Unlike the stoat, whose soles are thickly furred all year, the long-tailed weasel's soles are naked in summer.
