Breeding Range Map
The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, Breeding Bird Atlas (BBA), other datasets and experts throughout the state, as part of the Washington Gap Analysis Project. Habitats used during non-breeding months and migratory rest-stops were not mapped.

The Brewer's Blackbird is common at lower elevations in eastern Washington in a variety of habitats, including agriculture,wetlands, steppe and cities. It is found up into low-elevation forests. especially in northeastern Washington. Less abundant in western Washington, it is still found commonly throughout the Puget Trough, San Juan Islands, the Sequim area of Clallam County, south to Vancouver (Clark County) and west to Grays Harbor.

Core areas were all those below the Grand Fir zone (east side) and those below Western Hemlock (west side). In east-side zones below Interior Douglas-fir, good habitats were low-density development, water/wetlands, steppe, and forest openings and clearings. In all other zones, good habitats were imited to low-density development, agricultural, and likely west-side prairies and grasslands.

Brewer's Blackbirds are most often associated with agricultural fields. In eastern Washington, they are abundant throughout the agricultural areas and have benefitted from the conversion of steppe to agricultural lands. These blackbirds also coexist well with humans in eastern Washington steppe zones. In western Washington, Brewer's Blackbirds are most frequently found in agricultural areas at low elevations.
