It is the most recently recognized species of steamer duck, being described only in 1981.

A very similar species is the flying steamer duck.

Three species of steamer duck are almost flightless, however.

Some of these, such as the steamer ducks, show no appreciable changes in their flight feathers.

Another noticeable bird of the shores is the flightless steamer duck.

It is the only steamer duck which can fly, and the only one to occur on inland fresh waters.

It belongs to the steamer duck genus Tachyeres.

Steamer ducks frolicked in the surf and oystercatchers dug the softer sand scouting for food.

Tachyeres, steamer ducks (four species) - Tadorninae or closer to dabbling ducks?

The plumage of the Falkland Steamer Duck is mostly dark grey, but with a white stripe behind the eye.

The steamer ducks are a genus (Tachyeres) of ducks in the family Anatidae.

Together they belong to a South American lineage which diverged early from the other dabbling ducks and may include the steamer ducks.

Waterfowl include Chilean Flamingo, Upland Goose, and steamer ducks.

Other bird species residing in the area include Kelp Goose and Fuegian Steamer Duck.

His main research included the evolution of flightless birds, the ecology and the behaviour of steamer ducks, genetic analysis of birds, and avian diseases.

So we contented ourselves instead by watching a troupe of steamer ducks - quite flightless, like the rhea - whizzing maniacally through the waves, chasing a fishing-boat.

The Flying Steamer Duck, Tachyeres patachonicus, is a steamer duck.

Such rare aquatic birds as Magellan, kelp and ashy-headed goose, steamer ducks, black-crowned night herons and delicate Antarctic swallows provide almost continuous delight.

A crater nearby was filled with rainwater, and two silvery steamer ducks floated happily on the surface - a triumph of Nature's common sense over the irrationality of war.

Tachyeres, steamer ducks (four species) - Tadorninae or closer to dabbling ducks?

The Flying Steamer Duck, Tachyeres patachonicus, is a steamer duck.

In addition, the genus Anas, as traditionally defined, is not monophyletic; several South American species belong to a distinct clade which would include the Tachyeres steamer-ducks, and other species, such as the Baikal Teal, should also be considered distinct.

However, mtDNA sequence analyses of the cytochrome b and NADH dehydrogenase subunit 2 genes indicate that Tachyeres rather belongs into a distinct clade of aberrant South American dabbling ducks, which also includes the Brazilian, the Crested, and the Bronze-winged Ducks.
