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 genus name is derived from the Ancient Greek dendron, "tree", and Latin cygnus, "swan", [11] and bicolor is Latin for "two-coloured". [12] "Fulvous" means reddish-yellow, and is derived from the Latin equivalent fulvus. [13] Old and regional names include large whistling teal, [5] brown tree duck, Mexican duck, pichiguila, squealer and ...
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.
Whistling duck taxonomy, including that of the entire order Anseriformes, is complicated and disputed. [4] Under a traditional classification proposed by ornithologist Jean Théodore Delacour based on morphological and behavioral traits, [ 5 ] [ 6 ] whistling ducks belong to the tribe Dendrocygnini under the family Anatidae and subfamily ...
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]
