Canvasback Duck. The Canvasback (*Aythya valisineria*) is a large, striking diving duck native to North America and one of the most prized and recognizable waterfowl on the continent. The male is particularly distinguished by its rich chestnut-red head and neck, bright red eyes, and a distinctive sloping, wedge-shaped bill that gives its profile a uniquely streamlined appearance — quite different from most other ducks. Its back and sides display a pale, almost white canvas-like coloring (the source of its name), contrasting sharply with its black breast and tail. Females are more subtly colored, with a pale brown head and body, but share the same characteristic sloping profile. Canvasbacks breed primarily in the prairie pothole regions of the northern Great Plains and Canada, nesting among cattails and bulrushes near water. They are strong, fast fliers and expert divers, feeding mainly on aquatic vegetation — particularly wild celery (*Vallisneria americana*), which lends them their scientific name and gives their meat a famously excellent flavor. Populations have fluctuated over the decades due to habitat loss and hunting pressure, making them an important species for conservation efforts across North America.
