The Fuegian steamer duck 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 inland when breeding.
Region
Southern South America (Patagonia and Tierra del Fuego)
Typical Environment
Occurs along rocky coasts, channels, and fjords from southern Chile and Chiloé southward through the Strait of Magellan to Tierra del Fuego and adjacent Atlantic coasts of southern Argentina. It favors kelp-lined shores, wave-washed reefs, and sheltered bays. In the breeding season it often uses adjacent sheltered lagoons, lakes, and slow rivers slightly inland. Nests are placed in dense grass, scrub, or among rocks near water with good visibility. It is largely sedentary, maintaining year-round territories along coastlines.

Also called the Magellanic flightless steamer duck, it propels itself across the water by thrashing its feet and short wings, as if a paddle steamer. It is among the heaviest ducks, with males often exceeding 5 kg, and is notably aggressive in defending territories and nests. Pairs are typically long-term and remain near the same stretch of coast year-round.

flightless; runs and 'steams' across water with rapid foot and wing beats
Social Behavior
