    Formal Taxonomy
    Animalia - Craniata - Aves - Passeriformes - Fringillidae - Loxia - Song differences between North American and European populations suggest that more than one species exists and that further study is warranted (Elmberg 1993).
    Migration
    true - false - false - Irruptive winter migrant. May wander irregularly during periods of population highs or food shortages (Terres 1980).
    Non-migrant
    true
    Locally Migrant
    false
    Food Comments
    Eats seeds (e.g., of conifers, birches, grasses, junipers, etc.) and insects; mainly conifer seeds, which also comprise diet of nestlings (Benkman 1990).
    Reproduction Comments
    May nest any month; depends in part on food supply. Clutch size is 2-5 (usually 3-4). Incubation lasts probably 12-14 days (Terres 1980). Young are fed by both parents, but sometimes by male only (presumably when female deserts and renests). Individual females possibly sometimes produce 2 broods per year (Benkman 1989, Benkman 1990).
    Ecology Comments
    Does not maintain a feeding territory when breeding.
