Brassemer de Patagonie Tachyeres patachonicus

A large, heavily built duck that is fairly common along rocky seacoasts and on lakes near the coast; also local and uncommon on larger lakes farther inland. Despite the name, rarely seen in flight; more often seen thrashing through the water like an old paddle steamer boat, hence the name. Male’s bill is mostly orange, while the female’s bill is mostly greenish. Plumage of both sexes is duller gray or brownish gray compared to Flightless Steamer-Duck; the two species sometimes occur together, but Flightless tends to be warier.
