Breeding

Moreno Valley, California, 13 May 2006

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.

Vocalisation

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.

Movements
