Canvasback

The Canvasback (Aythya valisineria) is a species of diving duck, the largest found in North America. It ranges from 48–56 centimetres (19–22 in) in length and weighs 862–1,588 grams (1.90–3.50 lb), with a wingspan of 79–89 centimetres (31–35 in). The Canvasback has a distinctive wedge-shaped head and long graceful neck. The adult male (drake) has a black bill, a chestnut red head and neck, a black breast, a grayish back, black rump, and a blackish brown tail. The drake's sides, back, and belly are white with fine vermiculation resembling the weave of a canvas, which gave rise to the bird's common name. The bill is blackish and the legs and feet are bluish-gray. The iris is bright red in the spring, but duller in the winter. The adult female (hen) also has a black bill, a light brown head and neck, grading into a darker brown chest and foreback. The sides, flanks, and back are grayish brown. The bill is blackish and the legs and feet are bluish-gray. Its sloping profile distinguishes it from other ducks. Advertisement
