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.

Loss of habitat owing to drainage of wetlands for cattle and agriculture is probably resulting in slow population declines, but is unlikely to affect seasonally flooded and deeper wetlands in the near future. Collection of eggs, capture as pets and possibly illegal hunting in some areas, are unquantified threats. Construction of a pipeline and road through the wetlands of the Cienaga Grande de Santa Marta and Isla de Salamanca in the mid-1970s obstructed tidal flow and caused extensive mangrove die-back, continuing until at least 1992. In the same area, there is domestic and industrial pollution and sewage, urbanisation and mangrove cutting.
