Tufted Duck
Aythya fuligula
The Tufted Duck is a medium-sized diving duck with a population of close to one million birds. The adult male is all black except for white flanks and a blue-grey bill. It has an obvious head tuft that gives the species its name. The adult female is brown with paler flanks, and is more easily confused with other diving ducks.
