The Flying Steamerduck (Tachyeres patachonicus) is a member of the Flying steamerduck family.

The duck mainly feeds on animal foods such as crustaceans, mollusks, shrimp and small fish. Small groups of a few to more than 20 often feed in shallow water and on the surface of the water.

They breed on the edges of lakes, rivers, ponds, and marshes in September-October. The combination of pairs is more fixed. Mating takes place in water or on the ground. Nests are built in grass or bushes near water, or in rock crevices or sandy slopes. The nest consists of a small amount of dead grass and a large amount of down feathers, which the female ducks use to line the nest with plants. After laying eggs, she plucks a large amount of down feathers from herself and places them in the nest. 5-10 eggs are laid per nest. After the eggs are laid, the eggs begin to incubate, and the female ducks bear the responsibility alone, the male ducks guard near the nest, and call loudly to warn when in danger. The incubation period is 27-30 days, and the young ducks become sexual early, and after hatching, they are covered with feather, and can swim and dive. Sexual maturity at 2 ages.
