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 bird is common, though somewhat erratic, throughout Washington in conifer-dominated forests. It is less common as a breeder in the Olympics than elsewhere.

All forest zones were core breeding areas, plus steppe zones at the edge of the Columbia Basin. Mixed and conifer forests were good habitat, and in zones above steppe, fresh water/wetlands were adequate.

Washington breeders represent the widespread western subspecies C. v. brooksi. This species is widespread through conifer forests of Washington, and can be found up to high elevations, including conifer forests throughout the Blue Mountains. Evening Grosbeaks are known to be key controllers of Spruce budworm populations.
