    Food Comments
    Feeds on insects (wasps, ants, beetles, moths, grasshoppers, etc); also eats spiders and pine seeds. Forages on outer branches and twigs as well as along tree trunks.
    Reproduction Comments
    Clutch size is 4-9 (usually 6-8). Incubation, by female, lasts 15.5-16 days. Nestlings are altricial. Young leave nest at 22 days (Terres 1980). Cooperative breeding has been documented in California and Arizona; breeding units consisted of 2-5 birds; helpers (mostly yearlings, and offspring or siblings of the birds they aided) were found at about 30% of all nests in northern Arizona; nests with helpers sometimes more productive than those without helpers (Sydeman et al. 1988).
    Ecology Comments
    Often found in association with yellow-rumped warbler, plain titmouse, or mountain chickadee. Social throughout year. Travels in small family groups after nesting season. Family groups form larger loose flocks in fall and winter. Winter groups average 5-15 individuals; forage as a flock and roost communally within group territory (Sydeman et al. 1988).
