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 species is uncommon at low elevations in freshwater wetlands and water bodies in eastern Washington and it is a rare and a local breeder in similar habitats in western Washington. On the west side it is mostly limited to the Puget Sound Trough region and may also breed along the Columbia River. Some specific western Washington sites with confirmed breeding records in recent years include Lake Terrell, ponds near Nooksack, Fir Island, and Lake Tapps. On the east side it is uncommon in the Columbia Basin and in the northern river valleys, especially along the Okanogan; they are also found east to the Palouse in scabland ponds where it is less common than in the Columbia Basin. They are not known to breed in ponds in southeastern Washington south of Rock Lake in Whitman County. There is one BBA record from Klickitat County. The Green-winged Teal is most likely to nest in wetlands with shrubby vegetation or trees. It is the least common breeder of the three teal species we mapped.

Good habitat in the core areas of use included all freshwater/wetlands in eastern Washington in steppe zones and locally in the Ponderosa Pine zone, and in western Washington in the Puget Sound Douglas-fir and Woodland/Prairie Mosaic zones. We did not model this species along the Columbia River in western Washington.

In eastern Washington, important nesting areas include Potholes Reservoir, Lake Lenore, and near the confluence of the Okanogan and Columbia Rivers, with large distances between records. Despite the availability of seemingly appropriate habitat in Yakima County, there are no known breeding records in the area. Many west-side birds are summering non-breeders. Where this species occurs along rivers, it is associated with slow moving sloughs or small bays.
