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 House Wren is common and widespread in eastern Washington at lower elevations in cuts, forest openings, burns, open pine forests, wetland edges, and residential areas. They are less common in the hottest part of the Columbia Basin, but locally common in western Washington in dry prairies of the San Juan Islands. They are uncommon in the same habitat near Sequim (Clallam County) and Fort Lewis (Pierce County; uncommon in residential areas of Bellingham (Whatcom County), Whidbey Island (Island County), Everett/Marysville (Snohomish County, northern Seattle (King County, and Vancouver (Clark County).

Core zones were (west side) the Woodland/Prairie Mosaic, Willamette Valley, and Puget Sound Douglas-fir zones, and (east side) the steppe, Ponderosa Pine, Oak, and Douglas-fir zones. In the Oak and Ponderosa Pine zones and parts of the steppe zones intermingled with forest zones at the edge of the Basin, all habitats except bare ground and high density development were good. Agriculture, shorelines (on the west side) and forest openings and clearings were good habitats.

In western Washington, the western subspecies T.a.parkmanii is restricted to dry shrubby situations at low elevations. Occasionally, sites where breeding occurs include prairies in the southern Puget Sound area, e.g., the Fort Lewis prairies, the San Juan Islands, and Whidbey Island. House Wrens are common in parts of the San Juan Islands. In eastern Washington, forest cutting may have increased available habitat for House Wrens by providing them with open shrubby areas. In agricultural areas, small un-plowed shrubby areas, shrubs around buildings, and isolated farm houses are often utilized, but House Wrens are not present in featureless cultivated areas.
