Canvasback - Aythya valisineria
The canvasback breeds from Alaska south and east to Nebraska and Minnesota. It winters on the the Great Lakes, on the Atlantic, Pacific, and Gulf Coasts, and in Mexico.
The canvasback is a diving duck and eats green aquatic vegetation. One of its favorite foods is wild celery (Vallisneria americana), in fact, that is where it gets its Latin name! It also eats pondweeds, water lilies, sedges, mollusks, small crustaceans, small fish, and insects.
Male and female canvasbacks form mating pairs before they reach their breeding grounds. The female lays 7-10 olive-green eggs in a nest of reeds and grass lined with down. The nest is made in the marsh and is attached to dense vegetation. The female incubates the eggs and cares for the young. The eggs hatch in about 24 days and the ducklings fledge when they are 56-70 days old.
During the non-breeding season, canvasbacks gather in large flocks or rafts on the water. The canvasback is a very good flier and can reach speeds of up to 70 mph. When they are migrating, they fly in large V-shaped formations. The canvasback has to take a running start on the surface of the water before it becomes airborne.
