Anhimidae
Sign in to saveAlso known as Screamer
The screamers are three South American bird species placed in family Anhimidae. They were thought to be related to the Galliformes because of similar bills, but are more closely related to the family Anatidae, i.e. ducks and allies, and the magpie goose, within the clade Anseriformes. The clade is exceptional within the living birds in lacking uncinate processes of ribs. 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).

Die Wehrvögel (Anhimidae) sind eine Familie südamerikanischer Gänsevögel (Anseriformes), die drei Arten umfasst. Obwohl sie in der Gestalt eher truthuhnartig wirken, sind sie die nächsten Verwandten der Entenvögel. Zu ihren für Gänsevögel ungewöhnlichen Merkmalen zählen der hühnervogelartige Schnabel, die nur partiell ausgebildeten Schwimmhäute zwischen den Zehen, die allmähliche Mauser der Flugfedern, so dass sie ihre Flugfähigkeit anders als die meisten Gänsevögel nie verlieren, sowie ein einzigartiges Netz an Luftsäcken direkt unter der Haut. Bekannt sind Wehrvögel für ihre außerordentlich lautstarken Rufe, die ihnen im Englischen zum Namen Screamers (Schreier) verholfen haben.

The screamers are three South American bird species placed in family Anhimidae. They were thought to be related to the Galliformes because of similar bills, but are more closely related to the family Anatidae, i.e. ducks and allies, and the magpie goose, within the clade Anseriformes.

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).
==Systematics and evolution== Anhimids are most similar to presbyornithids, with which they may form a clade to the exclusion of the rest of Anseriformes. Given the presence of lamelae in the otherwise fowl-like beaks of screamers, it is even possible that they evolved from presbyornithid-grade birds, reverting from a filter-feeding lifestyle to an herbivorous one.
