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 Nashville Warbler is common in exposed micro-habitats in eastern Washington conifer forests, mostly at lower elevations. In western Washington it is fairly common along the upper Skagit River in eastern Skagit and Whatcom Counties, and locally common in scattered pockets in Skamania and Clark Counties. It possibly is a rare breeder in the Blue Mountains.

Core zones were all east-side forested zones (below Alpine Parkland). Peripherally, core zones occurred in the Willamette Valley, Interior Douglas-fir, western Hemlock, and Sub-alpine Fir zones west of the crest along the Skagit River and in southwestern Washington. In the Oak and Ponderosa Pine zones, wetlands, forest openings and clearings and all forest were good habitats. In other zones, closed forests were excluded. Nashville Warblers are most common in the lower, dry forest zones, but there are confirmed and probable breeding records up to the Subalpine Fir zone. This species reaches its peak abundance in Garry Oak groves, especially those in southern Klickitat County. Currently, western Washington breeders are mostly found along the Skagit River in Whatcom and Skagit Counties.
