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 placement of the New World vultures has been unclear since the early 1990s. The reason for this is the controversial systematic history of the New World vultures as they were assumed to be more related to (or a subfamily of) Ciconiidae (the storks) after Sibley and Ahlquist work on their DNA-DNA hybridization studies conducted in the late ...
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 taxonomic placement of the turkey vulture and the remaining six species of New World vultures has been in flux. [13] Though both are similar in appearance and have similar ecological roles, the New World and Old World vultures evolved from different ancestors in different parts of the world. Some earlier authorities suggested that the New ...
The New World and Old World vultures are similar in appearance and have similar ecological roles, but evolved from different ancestors in widely separated parts of the world. The relationships between the two vulture groups is a matter of debate, with some earlier authorities suggesting that the New World vultures are more closely related to ...
It is the only species of New World vulture which preys on cattle. It occasionally harasses cows giving birth, but primarily preys on newborn calves, lambs, and piglets. [56] [32] In its first few weeks, a calf will allow vultures to approach it. The vultures swarm the calf in a group and then peck at the calf's eyes, nose, or tongue.
