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 vireo is locally common in riparin growth with cottonwood stands in western Washington (especially along the Nooksack and Skagit Rivers and at Fort Lewis); along the Columbia River, and in eastern Washington along major rivers. It is more widespread in northeastern Washington and southeastern Washington than elsewhere in the state.

Good habitat in core zones included riparian corridors in the areas mentioned above, in all zones where breeding is likely. These areas were always below the Mountain Hemlock zone (west side) and the Subalpine fir zone (east side). (Cottonwood forests are very rare at high elevations.) Locally, closed hardwood forests were included if cottonwoods were likely to be a significant component of those forests.

The patchy distribution in Washington for this species correlates with the distribution of large Black Cottonwood groves, which are usually limited to riparian areas. The Red-eyed Vireo is one of the most abundant species in the northeastern United States, but is much less common in our state due to limited habitat.
