Yellow Headed blackbird

The Yellow headed blackbirds are fairly large, with a stout body, a large head, and a long conical bill. Males are striking black birds with yellow heads and chests, and black bodies with prominet white patches at the bend of the wing. Females and young blackbirds are brown instead of black with a duller yellow head. Immature mates show some white at the bend of the wing while females do not.

Yellow headed black birds breed in loose colonies and males mate with several females during the breeding season. The blackbird naturally eats insects and other aquatic invetebrates. They form huge flocks in winter often mixing with many other species of blackbirds.  Yellow headed blackbirds breed and roost in freshwater wetlands with dense, emergent vegetation such as cattails. They often forage in fields, typically wintering in large, open argricultural areas.
