The traditional grouping of the Falconiformes has, however, largely been kept together as a matter of convenience ... But this does not reflect the real position, which may be in the Ciconiiformes or in a separate order Cathartiformes. We should regard the cathartid vultures as sharing a common ancestor with the stork.)
