Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It occurs on high mountains in clearings and forest edges; pine, spruce, and fir forests. Most common where pine and Douglas-fir overlap (Hilton and Best 1993). Only in moist mesic higher forests in some areas (e.g., San Mateo and Magdalena mountains) (Findley et al. 1975). May be common in oak-juniper habitats in some areas. Perches on logs and stumps, commonly climbs trees. Nests are placed under logs, stumps, and roots, or in hollows of trees (Hoffmeister 1986), including woodpecker holes.

In Arizona: young are born in the first half of June; gestation lasts at least 30 days; individual adult females produce one litter of 4-6 young annually; nursing period lasts 41-45 days; young appear above ground by late July (Hoffmeister 1986).

Diet includes seeds, acorns, fruits, fungi, some green vegetation, and insects. Commonly forages in trees. Stores food.
Reportedly active March-November in Arizona, though above-ground activity may occur during warmer periods in winter (Hoffmeister 1986, Hilton and Best 1993).
