Scientific classification
Kingdom: Animalia
Class: Aves
Superorder: Accipitrimorphae
Order: Accipitriformes


Accipitriformes is an order which includes 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 was to include them with the falcons in the Falconiformes. However, a recent DNA study has shown that falcons are not closely related to the Accipitriformes. Instead, they are related to parrots and passerines.[1]

Since then putting the falcons next to the parrots in taxonomic order has been adopted by most ornithologists. The DNA-based proposal includes the New World vultures in the Accipitriformes,[1] but the American Ornithologists' Union (AOU) classifies the New World vultures as a separate order, the Cathartiformes.[2]
