The Cathartiformes / k ə ˈ θ ɑːr t ɪ f ɔːr m iː z / 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.
Accipitrimorphae is a clade of birds of prey that include the orders Cathartiformes (New World vultures) and Accipitriformes (diurnal birds of prey such as eagles, hawks, osprey and secretarybird).
Among them is the family Cathartidae (New World vultures) which the American Ornithological Society (AOS), the Clements taxonomy, and BirdLife International's Handbook of the Birds of the World place in its own order, Cathartiformes.
The DNA-based proposal and the NACC and IOC classifications include the New World vultures in the Accipitriformes, [7] [11] while the SACC classifies the New World vultures as a separate order, the Cathartiformes. When Cathartiformes is considered a separate order, sister to Accipitriformes, Accipitriformes sensu lato is called Accipitrimorphae.

Nevertheless, these groups, together with the genera currently recognized as belonging to the Viperinae, are still often referred to collectively as the true vipers. [ 3 ] Broadley (1996) recognized a new tribe, Atherini, for the genera Atheris , Adenorhinos , Montatheris and Proatheris , the type genus for which is Atheris .
This is a list of all genera, species and subspecies of the subfamily Viperinae, otherwise referred to as viperines, true vipers, pitless vipers or Old World vipers. It follows the taxonomy of McDiarmid et al. (1999) [1] and ITIS. [2] Atheris, Bush vipers Atheris acuminata; Atheris anisolepis; Atheris barbouri, Uzungwe mountain bush viper ...
