Flightless Steamer-duck (Tachyeres pteneres) - 18Feb2022

This large flightless duck of Chile and the Tierra del Fuego area of South America is huge, approaching goose territory.  They have spurs on their wings that they can use to fight each other or even other species.   We had a bunch of them when taking a ferry in the Tierra del Fuego area in Argentina near Ushuaia.  As you can see from my second picture, they can sink below the water's surface much like a Pied-billed Grebe.
