Fairly common breeder in freshwater wetlands and ponds in lowlands on both sides of the Cascade crest. Western Washington breeding areas are somewhat limited to the Puget Trough area and coastal locations. In eastern Washington, found in most steppe zones in appropriate habitat. In northern counties, found in the Ponderosa Pine zone along river valleys. Overall, more common throughout the state than the Greeen-winged Teal, but less common that the Cinnamon Teal.
Good habitat in core zones included all freshwater bodies in the Puget Sound Douglas-fir, Woodland/Prairie Mosaic, Cowlitz River, Western Hemlock and Sitka Spruce zones in western Washington, limited to the Puget Trough and coastal locations between Grays Harbor and the Columbia River. Below the Western Hemlock zone, agriculture, open areas in forests, and city parks were also included as suitable if appropriate habitat is available within the larger mapped habitat. In eastern Washington, good habitats in core zones were water/wetlands in steppe and Ponderosa Pine zones.
Washington breeders represent the nominate subspecies A. d. discors. Many west-side birds are summering non-breeders. Nesting of this eastern species in Washington has increased dramatically in the last century. Since 1900, when it was accidental in the state, this teal has established itself as a breeder and managed to increase such that it now outnumbers the Cinnamon Teal 2:1 in some areas of eastern Washington. The causes for this rapid increase are probably large damming projects and agricultural conversion in the 1950's, which inundated small wetlands and created large reservoirs, tipping the balance in favor of the Blue-winged Teal.
