The blue-winged teal is one of Oregon's least common ducks. It is a small, warm-weather duck usually found in Oregon only from late spring until the weather cools in early fall.
Except for adult drakes in alternate plumage, blue-wings are difficult to distinguish from cinnamon teal. For that reason its status in Oregon is less clear than that of other ducks. Adult blue-wing drakes have a gray head with white crescent between the eye and bill. Hens and young of both species are nondescript small brown ducks, but show the prominent blue wing-covert patch in flight.
It is an uncommon summer resident and common spring and fall migrant in northeast Oregon.
