Magellanic Flightless Steamer Duck Tachyeres pteneres
This heavily built duck is one of three closely related species, all from South America, that have lost the ability to fly. Like other steamer ducks, it has mottled gray plumage, yellow legs, and a robust, yellow-orange bill. It feeds on mussels, crabs and other small animals, diving among kelp beds to find its food. If threatened, it paddles noisily across the water with its wings, a behavior known as “steaming.”
