The Fuegian steamer duck (Tachyeres pteneres), also called the Magellanic flightless steamer duck, is a flightless duck from South America that has small wings. 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 inland when breeding. The genus name Tachyeres, "fast rower", comes from the ancient Greek ταχυ- "fast" + ἐρέσσω "I row (as with oars)". The common name "steamer ducks" arose because, when swimming fast, the ducks flap their wings in the water as well as using their feet, creating an effect like a paddle steamer. (Source: Wikipedia)
