Character Abstract
Identification Comments:
Subspecies Comments:
Food Habits:They feed on the fruits of forest trees and shrubs, ground-level herbs, grasses, fungi, and occasionally insects. Allen's chipmunk forages on log-strewn forest floors and in adjacent chaparral as well as in trees.
Phenology Comments:
Reproduction Comments:Nests located among logs or brush and in hollow trees. Mates in approximately late April. An average of 4 young are born in May-June after a 28-day gestation period.
Migration Mobility:
Habitat Comments:Allen's chipmunk, sometimes referred to as the Shadow chipmunk, is a large mountain chipmunk that generally prefers mature coniferous forests and chaparral slopes dominated by ponderosa pine, Jeffrey pine, sugar pine, black oak, Douglas fir, white fir, red fir, incense cedar, and mountain hemlock. The shrub layer includes buckbrush, manzanita, blackberry, and chinquapin. A study in the Sierra Nevada found that Allen's chipmunk was most abundant in red fir, than in mixed conifers (Coppeto et al., 2006).
Ecology comments:Nests are located among logs or brush and in hollow trees. During the winter, it undergoes deep hibernation periods, with little or no active periods.
