A large and flightless, grayish, heavy-set duck. Adult males have a bright orange bill; in females and juveniles, the bill is olive-green. Very similar to Flying Steamer-duck, and not easily identified; look for shorter, stunted wings and tail and thicker neck and bill. Found along the coast, where it favors small rocky islands, as well as sheltered inlets and bays. Also inhabits coastal ponds, but doesn’t venture farther inland, unlike Flying Steamer-Duck.
