The horned screamer ( Anhima cornuta ) is a kind from the family of screamers that the closest relatives of ducks counts. It is the only representative of the horned warbler genus ( Anhima ).
The Hornwehrvogel is a large, chicken-like-looking bird with fairly high legs. When fully grown, it reaches a body length of 84 centimeters and then weighs between two and three kilograms. This makes it the largest of the three species of defense bird. The body plumage is black and white with a narrow, up to ten centimeters long extension that points from the forehead upwards.
The head, which ends in a beak, as it is often found in this family, contributes to the resemblance to chicken birds . There is only a hint of webbed feet between its long toes, due to the similarities in the muscle system and bone structure, this species is classified as close to duck birds .
The horned warbler is a resident bird of tropical South America and occurs from Colombia to Brazil to northern Argentina. The diet consists mainly of aquatic plants. But he also grazes often on land. The female lays four to six eggs in a nest on the ground. The young birds hatch after six weeks.
