Andean condor Vultur gryphus, copyright Andres Bertens.

Belongs within: Telluraves.
Contains: Accipitridae.

The Accipitriformes are a clade of mostly predatory birds united by molecular data. Members of this clade have sharply hooked bills and powerful feet with an opposable hind toe and long claws, but these features may also be found in other bird clades.

The New World vultures and condors of the Cathartidae are basal Accipitriformes that are probably close relatives of the fossil Teratornithidae. Cathartids are specialised scavengers but teratorns were active predators.
