The Canvasback is the largest of the true pochards. This large diving duck is found only in North America where it is considered to be widespread. 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 adult female (hen) also has a black bill, a light brown head and neck, grading into a darker brown chest and fore back. They can be raised along with other birds as they get along with other birds well. Canvasbacks can be difficult to breed in captivity. They are fertile in their first year but often do not breed until they are 2-3 years old. Clutches consist of 6-8 eggs which are incubated for about 25 days.
