    Food Comments
    Opportunistic; in some areas, largely a scavenger on various animals; also commonly eats bird eggs and young, rodents, some fruits, cereal grains, insects.
    Reproduction Comments
    Clutch size is 3-7 (usually 3-6). Incubation is entirely or mostly by female (fed by male), 18-21 days. Young are tended by both parents, leave nest in 5-6 weeks. When food supply is limited, smallest chick often does not survive. Young remain with parents for several weeks after fledging.
    Ecology Comments
    May roost communally in groups of up to several hundred individuals (e.g., see Wilson Bull. 104:105-121). <br><br>Home range size of breeding birds was 0.2-4.4 square kilometers in coastal California, where ranges of nesting pairs sometimes overlapped; breeding season home range averaged 6.6 square kilometers in Utah, 9.4 square kilometers in Wyoming (see Linz et al. 1992). Territories in Minnesota were much larger, averaging 40.5 square kilometers (Bruggers 1998).
