The large, handsome canvasback can be found on lakes in Oklahoma from fall through spring, although in greater numbers in winter along the Gulf Coast.
A member of the group known as diving ducks, the canvasback is capable of diving over twenty feet down while foraging for aquatic plants and invertebrates. The long, sloping forehead and black bill, together with the white body of the male help distinguish the canvasback from its relative the redhead.
Canvasbacks are often seen in flocks together with scaup.
