Silky Pocket Mouse
Perognathus flavus bunkeri Cockrum
The silky pocket mouse is a small, delicate mammal that can be distinguished from other rodents by: 1) light yellowish to reddish-buff pelage intermixed with black hairs, 2) conspicuous pale yellowish patch of hair behind each ear that is at least twice the length of the ear, 3) soft, long, silky hair, 4) purer white underparts, 5) tail slightly darker on the dorsal surface but lacking a distinct stripe, 6) fur-lined external cheek pouches which open on each side of the mouth, and 7) grooved upper incisor teeth. Sexes are alike and seasonal color variation is minimal. Immatures are duller in color than adults.
