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 Winter Wren is common in all forested habitats in western Washington. In eastern Washington, it is common to uncommon in moist, closed conifer forests at higher elevations, usually above the Ponderosa Pine zone. It is found locally in lower-elevation forest zones of easter.

Core zone were those below the Alpine/Parkland zone and above the Ponderosa Pine and Oak zones. In all zones except Interior Douglas-fir and Ponderosa Pine, mid- and late-seral mixed and conifer forests were good habitats, while other forests, wooded riparian, alpine parkland, and wooded parks were adequate. In the Interior Douglas-fir and Ponderosa Pine zones were treated similarly, with the exception that in the Interior Douglas-fir zone, all open forest was adequate; while in the Ponderosa Pine zone, open forests were excluded.

Washington breeders represent the subspecies T.t.pacificus. Although ubiquitous in western Washington, the Winter Wren is less common and somewhat local in eastern Washington where they are usually noted at higher elevations than in western Washington, as these wrens generally avoid the dry open forest in the Ponderosa Pine zone. This species has been noted in the Cascades as a breeder to at least 6000 feet on Mount Rainier, where it may be found singing while many feet of snow still cover the ground. In cities, Winter Wrens will nest in suitable wodlands in some of the larger parks, e.g., at Sewat Park in Seattle (King County), but generally tend to shun developed areas during he breeding season.
