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.[2]

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,[2] but the American Ornithologists' Union (AOU) classifies the New World vultures as a separate order, the Cathartiformes.[3]
