Preferred habitats include fresh and saltwater marshes, rice paddies, sedge meadows, alfalfa fields, and other croplands.
Can fly at speeds of up to 30 mph during migration. Males sit with tails slightly flared.
Their main diet consists of seeds from grasses and other herbiage. They also eat a variety of insects and invertebrates.
Although primarily a marsh bird, the Red-winged Blackbird will nest near virtually any body of water and occasionally breeds in upland pastures. Each pair raises two or three broods a season, building new nest for each clutch. Each time they build a new nest, which keeps the nest from becoming infected with parasites that could kill the baby birds.
After the breeding season, the birds gather with other blackbirds in flocks, sometimes numbering in the hundreds of thousands. Although blackbirds are often considered pests because they consume grain in cultivated fields, farmers benefit because the birds consume harmful insects during the nesting season.
Song: Composed of a series of introductory notes konk-la-ree or gurr-ga-leee followed by a terminal buzz or trill.
Call: Short and relatively simple - low clack, sharp nasal deekk, and metallic tink.
Populations in western USA, Mexico and farther south are mostly resident. Those in northern and eastern North America are largely migratory.
Sightings of this bird were reported in 1600 by English settlers.
