Wikipedia Abstract

Townsend's chipmunk (Neotamias townsendii) is a species of rodent in the squirrel family Sciuridae. It lives in the forests of the Pacific Northwest of North America, from British Columbia through western Washington and Oregon. A large chipmunk, adults can be 36 cm (14 in) from nose to tail. In much of its range, it is the only chipmunk; it can be identified by its tail which is grayish above and reddish below, and by its brown coloration with indistinct tawny stripes. Townsend's chipmunk hibernates in regions where the winter is harsh, but in other parts of its range that have a more mild climate it can be active year-round. It is omnivorous, eating a variety of plants and insects and even birds' eggs. Townsend's chipmunks in the Oregon Coast Range have higher population densities in area
