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.
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.
This analysis argues that New World vultures should either be a part of a new order Accipitriformes [19] or part of an order (Cathartiformes) closely related to, but distinct from, other birds of prey. [18] New World vultures are a sister group to Accipitriformes, [18] a group consisting of Accipitridae, the osprey and secretarybird. [20]
The DNA-based proposal and the NACC and IOC classifications include the New World vultures in the Accipitriformes, [2] [6] but the SACC classifies the New World vultures as a separate order, the Cathartiformes [7] which has been adopted here. The placement of the New World vultures has been unclear since the early 1990s.
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.
More recent authorities maintained their overall position in the order Falconiformes along with the Old World vultures [15] or place them in their own order, Cathartiformes. [16] However, recent genetic studies indicate that neither New World nor Old World vultures are close to falcons, nor are New World vultures close to storks. [17]
Order: Cathartiformes Family: Cathartidae The New World vultures are not closely related to Old World vultures, but superficially resemble them because of convergent evolution . Like the Old World vultures, they are scavengers, however, unlike Old World vultures, which find carcasses by sight, New World vultures have a good sense of smell with ...
A vulture is a bird of prey that scavenges on carrion.There are 23 extant species of vulture (including condors). [2] Old World vultures include 16 living species native to Europe, Africa, and Asia; New World vultures are restricted to North and South America and consist of seven identified species, all belonging to the Cathartidae family.
