Traditionally, the other bird of prey families Cathartidae (New World vultures and condors), Sagittariidae (secretarybird), Pandionidae (ospreys), 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.

[5] The cladogram of the Telluraves shown below is based on the study by Josefin Stiller and collaborators published in 2024.

This list includes the Cathartiformes (New World vultures) in the order Accipitriformes.
