Montana Field Guide

The bushy-tailed woodrat (the legendary pack rat of western stories) grows to approximately 15 inches and 11 ounces in Montana. Together with its flat, squirrel-like tail, long full whiskers, large hairless ears, and protruding eyes, its size makes it easy to recognize. Its coloring is lead gray on the back and outside and white, pinkish or buff on the feet, ears, and belly (Foresman 2001). It may also have black or dark brown hairs on the back, giving it a darker appearance. Juveniles can have blue-gray fur on top (Kritzman 1977).
