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.
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 ]
Flying steamer ducks inhabit aquatic areas at the southern tip of South America, specifically Chile and Argentina, Tierra del Fuego, and the Falkland Islands. [7] Genetic comparisons of Falkland Island steamer ducks suggest the species diverged from continental steamer duck species between 2.2 and 2.6 million years ago, coinciding with a proposed land bridge that may have once connected the ...
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]

A small, freely-moving projection on the anterior edge of the wing of modern birds (and a few non-avian dinosaurs)—a bird's "thumb"—the word is Latin and means 'winglet'; it is the diminutive of ala, meaning 'wing'. Alula typically bear three to five small flight feathers, with the exact number depending on the species.
However, with the size of Gastornis legs, the bird would have had to have been more agile to catch fast-moving prey than the fossils suggest it to have been. Consequently, Gastornis has been suspected to have been an ambush hunter and/or used pack hunting techniques to pursue or ambush prey; if Gastornis was a predator, it would have certainly ...
