Patagonian steamer duck (Tachyeres patachonicus) - the most widespread of the steamer ducks. It is found in southern Chile and Argentina, in the Falkland Islands and Tierra del Fuego islands. The main difference between Patagonian steamer ducks and their relatives is their ability to fly (the fact is that the other 3 types of steamer ducks are flightless). It is also the only type of steamer ducks found in inland fresh waters (lakes, ponds and rivers).
Outside the breeding season, they can be found along the rocky coastlines. Patagonian steamer ducks get their food - aquatic invertebrates - exclusively by diving. They breed in October-November. Males during this period become extremely aggressive in defending their territories. These ducks usually nest among dense thickets, often on small islands.
All steamer ducks live along the sea coasts of southern South America, and they are called "steamers" because they noisily begin to rake the water with their wings, resembling a paddle steamer when fleeing danger, or during mating games. Steamer ducks weigh 3-6 kg and feed on molluscs and crustaceans.
Falkland Steamer Duck
The Falkland Steamer Duck is a flightless waterfowl of the duck family, which is one of two endemic species in the Falkland Islands, where it lives on the rocky shores.
The specific epithet in the name comes from other Greek. βραχύς - short and πτερόν - wing and was given to the species because its wings are so short that it is not capable of flight. The plumage of the steamer duck is mostly dark gray, but there is a white stripe behind the eyes.
Representatives of the species reach a length of 61 - 74 cm and weigh from 3.4 to 4.42 kilograms
