Habitat and Ecology [top]

Habitat and Ecology:It prefers dry shrubland habitat. Occupies dense brushy areas along ridges that are remnants of old banks of Rio Grande.

Like other pocket mice, it forages for seeds and stores them in the fur-lined cheek pouches. In southern Texas, its diet includes seeds of hackberry, mesquite, and other shrubs. It is nocturnal, staying in burrows during the day. The entrance to the burrow is often covered with leaves or other vegetation, or with a small mound of soil. This species breeds throughout the year, but peak reproductive period appears to be during the fall or winter. The number of young varies from two to eight, with an average litter size of four (Wilson and Ruff 1999).
Generation Length (years):2
