Tufted duck

The adult male is all black except for white flanks and a blue-grey bill with gold-yellow eyes, along with a thin crest on the back of its head. 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.

The Tufted Duck feeds mainly by diving, but they will sometimes upend from the surface. They eat insects and some plants and sometimes feed at night.
