The Red-winged Blackbird is a species of bird related to orioles, grackles, and other blackbirds. They are widespread across much of North America. Birds that summer farther north are migratory. Males are black overall, with red and yellow wing patches. Females are streaky brown.
Red-winged Blackbirds nest in wetlands and marshes, building their nests in cattails, grasses, and other vegetation. Females build a basket nest alone, and typically lay 3 to 4 eggs.
Red-winged Blackbirds are omnivorous, eating seeds, fruits and plant material as well as insects. During breeding season they will also feed on small animals like snails, worms, and mollusks. They are not above eating carrion, when available. In winter they will feed in large mixed flocks with other blackbirds and related species.
