Can be distinguished from Red-billed Teal by the uniformly coloured head and lack of a dark cap. In flight it shows a dark greenish speculum surrounded by white. Usually occurs in mixed flocks.
Juvenile is paler grey than adult.
Any open area of fresh or saline water.
A thin whistle, usually given in flight.
