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 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 three flightless species are monophyletic, with the flying steamer ducks splitting off phylogenetically. [3] It is the only steamer duck which can fly, and the only one to occur on inland fresh waters. [3] However, some individual male flying steamer ducks within the species are incapable of flight due to excessive size and wing loadings. [3]
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 ]
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]
Viktor Stepanovich Grebennikov (Russian: Виктор Степанович Гребенников; 23 April 1927 in Simferopol – 2001 in Novosibirsk) was a self-proclaimed Russian scientist, biologist, entomologist and paranormal researcher best known for his claim to have invented a levitation platform which operated by attaching dead insect body parts to the underside.
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
Of the 2530 endemic species, 238 are found only in Brazil and 337 are only in one of 12 other countries and territories. Seventeen of the 3485 total species have been introduced to South America. In addition, 106 of the species are vagrants to the continent, with only a few records, and some have made only a single appearance.
