Habitat and Ecology [top]

Habitat and Ecology:This species is found in various arid and semiarid upland habitats (usually with sparse vegetation) with loose sandy to clayey soil; dry grasslands, floodplains with scattered cottonwoods (southwestern North Dakota), sagebrush-shadscale (Utah). Sleeping and birthing occur in underground burrows. Gestation lasts about four weeks. Young are born from mid-May to July or August. Most studies indicate two litters per year. Litter size averages four to six, with a range of two to nine embryos. (Manning and Jones 1988).

This pocket mouse primarily eats weed seeds. It may eat some insects during the early summer. Collects food in external cheek pouches and stores it in underground chambers. Known to feed on seeds of knotweed, Russian thistle, pigweed, foxtail grass, etc. May become torpid for short periods during the winter and summer. In Canada it appears to remain in burrow from mid-October to mid-April; dormant periods probably alternate with periods of activity during this time. Primarily solitary. Predators include owls, weasels, and badgers.
