The Green-winged Teal (Anas carolinensis) or American Teal is a common and widespread duck that breeds in the northern areas of North America except on the Aleutian Islands. It was considered conspecific with the Eurasian teal (A. crecca) for some time, but the two have since been split into separate species. The American Ornithological Society[2] continues to debate this determination; however, nearly all other authorities consider it distinct based on behavioral,[3] morphological,[4] and molecular evidence.[5][6] The scientific name is from Latin Anas, "duck" and carolinensis, "of Carolina".

This dabbling duck is strongly migratory and winters far south of its breeding range. It is highly gregarious outside of the breeding season and will form large flocks. In flight, the fast, twisting flocks resemble waders.
