The '''screamers''' are three South American [[bird]] species placed in [[Family (biology)|family]] '''Anhimidae'''. They were thought to be related to the [[Galliformes]] because of similar [[beak|bills]], but are more closely related to the family [[Anatidae]], i.e. [[duck]]s and allies,<ref name=Carboneras-1992/><ref name=Todd/> and the [[magpie goose]],<ref name=Kricher/> within the clade [[Anseriformes]]. The clade is exceptional within the living birds in lacking [[uncinate processes of ribs]].<ref name=Fowler-Cubas-2001/> The three species are: The [[horned screamer]] (''Anhima cornuta''); the [[southern screamer]] or crested screamer (''Chauna torquata''); and the [[northern screamer]] or black-necked screamer (''Chauna chavaria'').
