Food Comments
Feeds on insects, seeds, waste grain, and fruit. Walks on the ground while foraging, sometimes follows plows to eat uncovered insects.
Reproduction Comments
Clutch size is 3-7 (usually 5-6). Incubation lasts 12-14 days (Terres 1980). Young are tended by both adults, fly 13-14 days after hatching. Sometimes two broods are produced in one season. Males may be polygamous. Nests in loose colonies (3-20 pairs).
Ecology Comments
Often seen in large flocks; may forage with other blackbirds. In California, individuals were found up to 10 kilometers from nest in breeding season (Williams 1952); in Washington, found up to 1.6 kilometers from nest, although most foraged much closer (Horn 1968).
