Temminck divides the genus into four sections. 1. The Goose ; 
2. The Swan ; 3. The Duck. A. Ducks having the hind claw

short, the second considerably shorter than the third : the fourth and 
fifth are of equal length, and the longest in the wing. Tail short, rather 
rounded and carried erect. Legs strong : shank of the same length as
