Ecology & Life History | |||||||||||
General Description: | |||||||||||
Global Reproduction Comments: | Breeds in early spring. Average litter size is 5 (Washington) to 6 (California); 1 litter/year in Washington Cascades (Kenagy and Barnes 1988). Young are born from mid-May to early June (Banfield 1974), weaned in about 6 weeks; first appear at surface in June in Washington Cascades; first breeds at 1 year (Kenagy and Barnes 1988). May live up to 5 years. | ||||||||||
Global Ecology Comments: | Home range is a few acres, parts of which may be used seasonally (see Sutton 1992). In Washington, density was fairly stable over 3 years at 1.25/ha (see Sutton 1992). Easy prey for many kinds of predators. Competitive interactions with other chipmunk species may limit habitat use. Effective dispersal agent for Jeffrey pine seeds (Vander Wall 1992; see also Vander Wall, 1993, Oecologia 96:246-252). | ||||||||||

Global Habitat Comments: | Generally in brushy areas interspersed with herbaceous vegetation and open conifer stands; shrubs typically present include snowberry, chinquapin, mountain mahogany, antelope brush, currant, and buckbrush (Sutton 1992). Found among logs, brush, and rocky outcrops. Also in brushy areas between subalpine forest and alpine tundra, and in alpine areas themselves. Digs burrows 7-21" deep. Constructs grass nest in burrow under stump, log, or rock; also nests above ground in woody vegetation. | ||||||||||
Food Habits: |
Frugivore: Adult, Immature
Granivore: Adult, Immature Invertivore: Adult, Immature |
||||||||||
Global Food Habits Comments: | Diet consists of seeds, fruits, green foliage, flowers, roots, buds, bulbs, tubers, fungi, and small animals. Caches food in burrow and in scattered pits dug in soil surface. | ||||||||||
Global Phenology: |
Hibernates/aestivates: Adult, Immature
|
||||||||||
Global Phenology Comments: | Hibernates late fall-early spring. May become lethargic during cold summer weather. Stores little energy as body fat; awakens periodically in winter to feed on stored seeds (Banfield 1974, Sutton 1992). | ||||||||||
Provincial Phenology: (1st half of month/ 2nd half of month) |
