The Accipitriformes is an order that has been proposed to include most of the diurnal birds of prey: hawks, eagles, vultures, and many others, about 225 species in all. For a long time, the majority view has been to include them with the falcons in the Falconiformes, but some authorities have recognized a separate Accipitriformes. A recent DNA study has indicated that falcons are not closely related to the Accipitriformes but are instead related to parrots and passerines so the split (but not the placement of the falcons next to the parrots or passerines) has been adopted by the American Ornithologists' Union's South American Checklist Committee (SACC), its North American Checklist Committee (NACC), and the International Ornithological Congress (IOC).
