For a long time, the majority view was to include them with the falcons in the Falconiformes, but many authorities now recognize a separate from Accipitriformes.[3][4][5][6] A DNA study published in 2008 indicated that falcons are not closely related to the Accipitriformes, being instead more closely related to parrots and passerines.[7] Since then, the split and the placement of the falcons next to the parrots in taxonomic order has been adopted by the American Ornithological Society's South American Classification Committee (SACC),[8][9][10] its North American Classification Committee (NACC),[11][12] and the International Ornithological Congress (IOC).[13][14] The British Ornithologists' Union already recognized the Accipitriformes,[15] and has adopted the move of Falconiformes.[16] The DNA-based proposal and the NACC and IOC classifications include the New World vultures in the Accipitriformes,[7][11] while the SACC classifies the New World vultures as a separate order, the Cathartiformes.
