The similarities between the two groups of vultures are due to convergent evolution, rather than a close relationship. They were widespread in both the Old World and North America during the Neogene. Old World vultures are probably a polyphyletic group within Accipitridae, belonging to two separate not closely related groups within the family. [2]
Vultures are a result of convergent evolution: both Old World vultures and New World vultures eat carrion, but Old World vultures are in the eagle and hawk family (Accipitridae) and use mainly eyesight for discovering food; the New World vultures are of obscure ancestry, and some use the sense of smell as well as sight in hunting. Birds of both ...
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.
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 griffon vulture is 93–122 cm (37–48 in) long with a 2.3–2.8 m (7 ft 7 in – 9 ft 2 in) wingspan. In the nominate race the males weigh 6.2 to 10.5 kg (14 to 23 lb) and females typically weigh 6.5 to 10.5 kg (14 to 23 lb), while in the Indian subspecies (G. f. fulvescens), the vultures average 7.1 kg (16 lb).

Just how different the two families are is currently under debate, with some earlier authorities suggesting that the New World vultures are more closely related to storks. [9] More recent authorities maintain their overall position in the order Accipitriformes along with the Old World vultures [10] or place them in their own order ...
