The order Falconiformes is represented by the extant family Falconidae and a handful of enigmatic Paleogene species. Traditionally, most other diurnal bird of prey families Cathartidae, Sagittariidae (secretarybird), Pandionidae (ospreys), and Accipitridae (hawks) were classified in Falconiformes. A variety of comparative genome analyses published since 2008, however, found that falcons are part of a clade of birds called Australaves, which also includes seriemas, parrots and passerines. Within Australaves falcons are more closely related to the parrot-passerine clade than they are to the seriemas. The hawks, vultures and owls are placed in the clade Afroaves.
