Canvasbacks are diver ducks well equipped with their own form of flippers-large webbed feet that make them smooth and graceful swimmers.

The Canvasback (Aythya valisineria) is a large 15-inch duck with a 34-inch wingspan. The head and neck are copper colored, with a black breast and tail, pale gray back and sides and white belly. The wedge-shaped head is distinctive.
The canvasback breeds in freshwater prairie marshes and swamps from Alaska south and east to Nebraska and Minnesota. It winters in on the the Great Lakes; on the Atlantic, Pacific and Gulf Coasts and in Mexico.
