Description

The San Joaquin Pocket Mouse vocalizes with low grunts, growls, and squeals, and communicates aggression by tooth-chattering. This species will consume earthworms and soft-bodied insects, but its diet is mainly very tiny seeds of grasses, forbs, and shrubs. Its burrows are conspicuous in the short grass where it lives, in west-central California. To groom their fur, San Joaquin Pocket Mice sandbathe, digging into the loose sandy soil and then sliding and rubbing their bodies in the sand.
