Long-tailed Weasel

Open encyclopedia reference

The long-tailed weasel (Neogale frenata), also known as the bridled weasel, masked ermine, or big stoat, is a species of weasel found in North, Central, and South America. It is distinct from the short-tailed weasel (Mustela erminea), also known as a "stoat", a close relation in the genus Mustela that originated in Eurasia and crossed into North America some half million years ago; the two species are visually similar, having long, slender bodies and tails with short legs and a black tail tip.

Long-tailed weasels exhibit scale-dependent patterns of habitat selection, favoring forest patches, fencerows, and drainage ditches while avoiding agricultural fields. They typically make their habitats in forests and underground in burrows of other small mammals.
