Accipitrimorphae is a clade of birds of prey that includes the orders Cathartiformes (New World vultures) and Accipitriformes (diurnal birds of prey such as eagles, hawks, osprey and secretarybird). Accipitrimorphae belongs to the clade Telluraves. Historically, some authorities included the New World vultures in the Accipitriformes, but recognition of Cathartiformes as a separate order subsequently became more widespread.
The phylogenetic placement of New World vultures was long debated. Based in part on DNA–DNA hybridization studies, Sibley and Ahlquist (1990) supported a close relationship between New World vultures and storks (Ciconiidae). Subsequent high-quality molecular phylogenetic studies completely refuted the stork-vulture relationship, instead recovering them as a sister group to the order Accipitriformes. Catanach et al. (2024) discovered that the two groups diverged 61.3 million years ago.
