Common Name: Green-Winged Teal
Scientific Name: Anas carolinensis
Order/Family: Anseriformes/Anatidae (Water Birds)
Description: This is the smallest North American dabbling duck. The breeding male has grey flanks and back, with a yellow rear end and a white-edged green speculum, obvious in flight or at rest. It has a chestnut head with a green eye patch. The Males have a vertical white stripe on side of breast. The females are light brown, with plumage much like a female mallard. They can be distinguished from most ducks on size, shape, and the speculum. Separation from female common teal is problematic. In non-breeding (eclipse) plumage, the drake looks more like the female.
Distribution: In northern areas of the United States, green-winged teal migrating to wintering grounds appear in early September through mid-December. They begin migrating into most central regions during September and often remain through December. On their more southerly winter areas, green-winged teal arrive as early as late September, but most do not appear until late November.
Habitat: Green-winged teal inhabit inland lakes, marshes, ponds, pools, and shallow streams with dense emergent and aquatic vegetation. They prefer shallow waters and small ponds and pools during the breeding season.
