Region
North America
Typical Environment
Brewer's blackbird is widespread across western and central North America, breeding from southern Canada through much of the western United States and into parts of the Great Plains. It favors open habitats such as agricultural fields, grasslands, sagebrush flats, marsh edges, and urban parks and lots. The species readily exploits human-altered landscapes and often forages along shorelines and irrigation ditches. Northern breeders migrate south to winter across the southern United States and northern Mexico, while many western populations are resident.

Brewer's blackbird is a medium-sized New World blackbird named after ornithologist Thomas Mayo Brewer. Males shine with purple and green iridescence, while females are plain brownish-gray. Often comfortable around people, they forage in parking lots, fields, and parks, and can form large flocks outside the breeding season.

Social Behavior
Outside the breeding season, Brewer's blackbirds form sizable flocks, often mixing with other blackbirds and starlings. During breeding, pairs may nest semi-colonially in shrubs, small trees, or reedbeds, with the female building a cup nest. Males defend small territories and perform display postures with puffed plumage and raised head.
Migratory Pattern
Partial migrant
Song Description
The song is a short, buzzy series of squeaky, metallic notes, often introduced by a thin whistle. Calls include sharp 'chuk' and harsh rasping sounds, delivered from exposed perches or during display.
