The bushy-tailed woodrat is a large rat-like mammal; its squirrel-like tail unique among members of the genus, is gray above and whitish below. The dorsum is buffy gray to dark brownish-black and the venter is white to buff depending on the geographic race.

It occurs, statewide in a wide variety of habitats. It is active nocturnally. Sometimes, upon leaving the protection of its den, the woodrat may lie motionless on a rock or limb, watching for a long period before moving forth.
