Physical 

The canvasback is a duck with a very distinctive, high-sloped forehead. Males have a rusty head, a black chest and tail, and white body. Females are paler brown with a dusty body.

Habitat

Canvasbacks live in lakes, salt bays, estuaries, and freshwater marshes. Their range spans most of North America, parts of Alaska, western Canada, all of the continental US, and on into Mexico. Canvasbacks migrate seasonally. You will see canvasbacks in the Barnegat Bay during the winter.

Feeding 

Like most ducks, canvasback feed by diving into the water. In shallow areas, they will stir up the sediment and stick the front half of their body into the water to pick through it. Their diet consists mostly of plants like pondweed, wild celery, and various sedges and grasses. However, they also eat mollusks, insects, and some small fish.
