Open encyclopedia reference
The horned screamer (Anhima cornuta) is a species of waterfowl that belongs to a relatively small family, the Anhimidae, which occurs in wetlands of tropical South America. There are three screamer species, the other two being the southern screamer and the northern screamer in the genus Chauna. They are related to ducks, geese and swans, which are in the family Anatidae, but have bills looking more like those of Galliformes.
