Features: Except for adult drakes in breeding plumage, blue-wings are difficult to distinguish from cinnamon teal. 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.

Blue-winged teal is an early migrant and extremely rare winter resident in Oregon. Many hunters who believe they have shot a blue-winged teal actually have probably taken a hen or young drake cinnamon teal, both of which have identical wings with a large blue shoulder patch.
