The Flightless Steamerduck is distributed from Chiloe southwards to Tierra del Fuego. It is never found on freshwater and breeds near the shore.

It is a large duck with very short wings and incapable of flight. It does "steam" across the surface of the sea a bit like a paddle steamer (see the photos for Flying Steamer-duck).

Alvaro Jaramillo tells me that "the dull bill colour is a bit odd (like in Falkland birds) and may be age related."

They are often dull and worn down in flightless, and much more pointed and slimmer in flying." This bird certainly looks as though it has been in a fight recently judging from the blood on its head. You can see the smaller spurs on Flying Steamer-duck on photos 3 and 4 of that page.
