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 warbler is common throughout most of western Washington at lower elevations in mixed and hardwood forests, preferring sites with mature hardwood trees, such as maples, alders, willow, and Garry Oaks. It is less common in the San Juans, and very local and uncommon on Whidbey, Camano, Fidalgo Island; local and uncommon east of the Cascades in Kittitas and Yakima Counties at moderate elevations, but abundant in Klickitat County in riparian/oak groves.

Core zones were those below Silver Fir on the west side, plus in parts of the Interior Western Hemlock, Grand Fir, Interior Douglas-fir, Oak and Ponderosa Pine Zones east of the crest. The Silver Fir zone was peripheral. Good habitats were wooded parks, agriculture, fresh water/wetlands, forest openings and clearings, hardwood forest, mixed forest, and early-seral conifer forest. East-side zones were similar except that all conifer forests were excluded. In the Ponderosa Pine and Oak zones, forest openings and clearings and non-irrigated agriculture were also excluded.
