horned screamer

The horned screamer (Anhima cornuta) is a member of a small family of birds, 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 the  ducks, geese and swans, which are in the family Anatidae, but have bills looking more like those of game birds.
