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.

This aggressive species is widespread and abundant at lower elevations of the State of Washington, in, virtually every habitat as long as a suitable microhabitat with emergent vegetation is available. Can be found along roads where ditches have created suitable habitat. Rarely, they will nest in upland shrubby areas.

Core areas of habitat were all water/wetlands (including estuaries) below the Silver Fir zone (west side) and below the Sub-alpine Fir zone (east side). All other habitats except bare ground were suitable if small pockets of wetland occurred within the larger mapped habitats.

Washington birds represent two poorly distinguished subspecies, A.p. caurinus of western Washington and A.p. nevadensis of eastern Washington. Red-winged Blackbirds are extremely adaptable, successfully colonizing many small wetlands created by human activities such as farming, road building, and industrial wetlands.
