The flying steamer duck, also known as the flying steamer-duck or flying steamerduck, is a species of South American duck in the family Anatidae.

The Falkland steamer duck is a species of flightless duck found on the Falkland Islands in the South Atlantic Ocean. The steamer ducks get their name from their unconventional swimming behaviour in which they flap their wings and feet on the water in a motion reminiscent of an old paddle steamer. The Falkland steamer duck is one of only two bird species endemic to the Falkland Islands, the other being Cobb's wren.
