The Cathartiformes /kəˈθɑːrtɪfɔːrmiːz/ was a former order of scavenging birds which included the New World vultures and the now-extinct Teratornithidae.[1] Unlike many Old World vultures, this group of birds lack talons and musculature in their feet suitable to seize prey. 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 suggested a stronger phylogenetic relationship between Cathartiformes and the families of Accipitriformes,[4] and they are now normally included within the Accipitriformes as the family Cathartidae.[5]
