The Fuegian steamer duck (Tachyeres pteneres) or the Magellanic flightless steamer duck, is a flightless duck native to South America. It belongs to the steamer duck genus Tachyeres . It inhabits the rocky coasts and coastal islands from southern Chile and Chiloé to Tierra del Fuego , switching to the adjacent sheltered bays and lakes further ...
The steamer ducks are a genus (Tachyeres) of ducks in the family Anatidae. All of the four species occur at the southern cone of South America in Chile and Argentina, and all except the flying steamer duck are flightless ; even this one species capable of flight rarely takes to the air.
Thambetochen is an extinct genus of moa-nalo duck. It contains two species, the Maui Nui moa-nalo (T. chauliodous) and the smaller O'ahu moa-nalo (T. xanion).

The Falkland steamer duck (Tachyeres brachypterus) 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. [ 3 ]
The flightless species is only known from bones and was presumably driven extinct by visiting sealers and the rats they introduced. [3] A 1696 sighting by William de Vlaming of "four-footed animals" in the reeds of Amsterdam Island may have been of this duck, as there are no native land mammals on the island. [3]
Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, flattened bills, and feathers that are excellent at shedding water due to an oily coating.
About 60 extant bird species are flightless, as were many extinct birds. [215] Flightlessness often arises in birds on isolated islands, probably due to limited resources and the absence of land predators. [216] Though flightless, penguins use similar musculature and movements to "fly" through the water, as do auks, shearwaters and dippers. [217]
Due to the Chubut Steamer ducks being flightless, they need to have different methods of escaping predators besides flying. [4] To do this they can swim, dive or steam. Steaming is a faster unique way to swim for these flightless birds. When they steam they use their wings as oars and their feet to generate turbulence. [4]
