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 Varied Thrush is common in conifer forests throughout the state. In western Washington, it is found in all forest zones. In eastern Washington, it is limited to higher-elevation montane and sub-alpine forests

Good habitat in core zones included all mixed and conifer forests in all zones of western Washington, and above the Ponderosa Pine and Oak zones in eastern Washington.

Both subspecies of Varied Thrush breed in Washington, I.n.naevius in western Washington and I.n.meruloides in eastern Washington. In eastern Washington, the Varied Thrush is generally found above the Ponderosa Pine zone.
