The Green-winged Teal is a small North American duck, notable for the green stripe on the male's head. It feeds near the water's surface and moves between breeding and wintering areas with the seasons.
The male has a gray body, a broad dark-green stripe across its head, and a narrow white shoulder stripe. The female is mottled brown, with dark lines around the eye and bill. A green patch on the forewing shows when the wing is extended.
This is a dabbling duck that feeds from the water's surface rather than diving. It eats grasses and pondweeds as well as aquatic insects, crustaceans, mollusks, and tadpoles; the mix varies by season and place.
