description Flightless Steamer-Duck Overview

The Flightless Steamer-Duck (Tachyeres pteneres) is a large, heavy-bodied waterfowl species found along the southern coasts of Chile and Argentina. It is named for its wing-thrashing movement across the water, which resembles a paddle steamer, and it is one of four steamer-duck species in the genus Tachyeres. Unlike the flying steamer-duck, it is entirely incapable of sustained flight and relies on its wings for aquatic propulsion. Its bulky build and aggressive territorial behavior are well documented among observers.
