    Food Comments
    Pine seeds are primary food for both adults and nestlings. Also eats insects, acorns, berries, snails, carrion; sometimes eats eggs and young of small birds. Nearly all winter food and much of breeding season food derived from pine seeds collected and stored in fall (Vander Wall 1988).
    Reproduction Comments
    Clutch size is 2-6 (usually 2-3). Incubation, by both sexes, lasts 17-18 days. Young leave nest 24-28 days after hatching.
    Ecology Comments
    May travel in large flocks (25-100 birds) (Terres 1980). Dixon (1934) reported foraging 0.8 to 2.4 km from nest, and Tomback (1998) reported a summer home range of 1500 hectares (roughly 4.4. kilometers in diameter). Year-round home ranges are much larger: 15,000 hectares in areas of good food (Tomback 1998).
