Bonaparte's Weasel

Images coming soon.

Length
11 inches (female 9 inches).
Description
Smaller, difference in sizes of sexes not so striking, tail decidedly shorter--not much more than one-quarter the total length. Dark brown above, tail tipped with black, belly and under parts white tinged with yellow. Pure white in winter with a yellow tinge on the rump, and tail black tipped.
Range
Boreal forests south to New England and the mountains of Pennsylvania. A larger variety, Richardson's weasel P. cicognani richardsoni (Bonaparte), occurs in Northern British America.

This smaller, short-tailed weasel is an animal of the boreal forests, overlapping in parts of its range one or other of the preceding long-tailed species, from which it probably differs little in habits.
