Ecology & Life History
General Description:
Global Reproduction Comments: Breeding occurs in the spring soon after females emerge from hibernation. Females are monoestrous. Gestation lasts 26-33 days. Litter size is 2-8, usually 4-6. Young emerge from burrow typically in July (to early August at highest elevations). Weaning occurs at minimum age of 4 weeks. Males do not take part in family life. A few may live up to 7 years.
Global Ecology Comments: Populations usually are distributed evenly over good habitat. Predators include snakes, foxes, weasels, and bears. This species may be an intermediate host for the Rocky Mountain spotted fever tick, DERMACENTOR ANDERSONI.

Habitats:
(Type / Subtype / Dependence)
Global Habitat Comments: Inhabits mountain slopes and foothills, alpine tundra, chaparral, open areas in pine, spruce, and fir forests, rocky outcroppings and slides, margins of mountain meadows, and rocky sagebrush country; campgrounds. Often in areas with abundant stumps, rocks, of fallen logs. When inactive or tending young, occupies burrows under rocks, stumps, logs, trees, bushes, or cabins, in rock crevices, or in banks or along washes.
Food Habits: Frugivore: Adult, Immature
Granivore: Adult, Immature
Herbivore: Adult, Immature
Global Food Habits Comments: Omnivorous. Feeds on seeds, fungus, leaves, flowers, fruits and roots. Also feeds on arthropods and meat, including carrion. In one study underground fungus comprised 65% of summer food and 90% of fall food. May store food in burrow in summer.
Global Phenology: Diurnal: Adult, Immature
Hibernates/aestivates: Adult, Immature
Global Phenology Comments: Active mainly March-November at low elevations; season is shorter in high mountains and in areas with abundant snowfall.
