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.
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 ...
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 Chubut steamer duck or white-headed flightless steamer duck (Tachyeres leucocephalus) is a flightless duck endemic to Argentina. [ 1 ] [ 2 ] It is the most recently recognized species of steamer duck , being described only in 1981.
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]
Flightless birds are birds that cannot fly. They have, through evolution, lost the ability to fly. [1] There are over 60 extant species, [2] including the well-known ratites (ostriches, emus, cassowaries, rheas, and kiwis) and penguins. The smallest flightless bird is the Inaccessible Island rail (length 12.5 cm, weight 34.7
Close-up of the head of a southern cassowary. Typically, all cassowaries are shy birds that are found in the deep forest. They are adept at disappearing long before a human knows they are there. The southern cassowary of the far north Queensland rain forests is not well studied, and the northern and dwarf cassowaries even less so. Females are ...
