The order Cathartiformes /kəˈθɑːrtɪfɔːrmz/ of raptors or birds of prey includes the New World vultures and the now-extinct Teratornithidae.[1] These raptors are classified by most taxonomic authorities in the order Accipitriformes (which includes the eagles and hawks). In the past, they were considered to be a sister group to the storks of the order Ciconiiformes based on DNA–DNA hybridization and morphology.[2][3] However, a 2021 analysis of mitochondrial genes among Accipitrimorphae, which include Cathartiformes, reinforced prior findings on the phylogenetic relationships between Cathartiformes and other subfamilies of Accipitriformes.[4]
