- Tachyeres brachypterus
Identification
Length 61-76 cm (24-30")
Short wings with rump and dorsal part extending beyond wing-tips. Overall mottled gray and brown, with conspicuous white eye-line that extends down the back of the neck. Underparts white. Male has bright orange bill with a large dark nail; head becomes gradually white as the bird gets older. The female is always dark-headed, slightly darker overall with a bill that is mostly greenish-grey.
Similar Species
Similar to Flying Steamer-Duck but with heavier neck, shorter wings and tail, and stouter bill. Occurrence of Flying Steamer-Duck on the Falkland Islands is controversial. All the Steamer-ducks are very similar in appearance.
Distribution
Taxonomy
This is a monotypic species[1].
Habitat
Coastal littoral.
Behaviour
Flightless. Forages off rocky coasts, particularly sheltered bays protected from strong waves. Pairs or small groups may flock in protected harbors.
