|Population:||This species is locally common in most portions of the range.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||It is found in various habitats, mainly rocky areas with conifers or shrubs, Pinyon-juniper or rock associations in Arizona (Hoffmeister 1986) and Oklahoma. In New Mexico, it is mainly coincident with the ponderosa pine zone; also in pinyon-juniper and scrub oak-juniper habitats and in open stands or edges of spruce-fir forest; similar habitats in Colorado. Primarily terrestrial but also an adept climber. Commonly perches on rocks, stumps, or logs (Best et al. 1994). |
Mating occurs in spring (e.g., late April-May in Colorado) throughout much of the range, bimodally in February and July in southern New Mexico. Gestation lasts about 30 days. Litter size is 2-6. Young are weaned at 6-7 weeks. Generally one litter per year, but the presence of pregnant and lactating females in late summer in some areas suggests a second litter or late breeding.
Home range averages a few hectares. Overwinter survival rate is less than 33%; local extirpation or near-extirpation is a common event (Best et al. 1994).
Diet includes seeds and fruits of various woody and herbaceous plants, and some insects. Feeds mainly on the ground but obtains some food by climbing into trees and shrubs. Stores food in underground caches. Generally not active above ground during coldest winter weather. Most active above ground in morning and late afternoon.
