Redheads go by many names, including red-headed ducks and red-headed pochards or diving ducks. This waterfowl is easily distinguished from other ducks by a male’s copper-colored head and bright blue bill. Ring-necked ducks look similar to redheads at a distance, but they have darker backs than redheads, with a white spur on their sides that redheads lack. Canvasbacks have similar color patterns, but they have distinct profiles, with long faces that slope unbroken from the top of their foreheads to the tips of their bills. Redheads have a more classic duck look, with a well-defined angle between their rounded heads and distinctive blue-gray bills.
