Seen among other Aythya species (primarily Redhead, Scaup, and a small number of Ring-necked Ducks). Male Canvasback can be seen on the left and the female on the right near the foreground, facing each other with what appears to be a Lesser Scaup between them (based on its significant head bump). Canvasbacks both have long sloping head/bill profile with dark bills (not blue), male with reddish brown head contrasting sharply with the light coloured back, the female have a light tan or canvas-coloured back.
