The Canvasback is a striking diving duck found across North America, especially in marshes, lakes, and bays. Males are known for their bold appearance: a chestnut-red head, black breast, and pale gray body. Females are subtler in color, with a light brown body and darker head. Both sexes have a long, sloping forehead that gives the head a distinct wedge shape.
Canvasbacks are strong swimmers and divers. They feed mostly underwater, using their bills to dig up aquatic plants like wild celery, which is a favorite. They also eat small invertebrates during the breeding season. Their feet are set far back on their bodies, making them excellent underwater movers but awkward on land.
During breeding season, they nest in prairie pothole regions, shallow wetlands in central Canada and the northern U.S. Females build nests over water, often hidden in dense vegetation. In winter, Canvasbacks gather in large flocks on open lakes, coastal bays, and estuaries, especially along the Gulf Coast.
