Description
The Turkey Vulture (Cathartes aura), also known in some North American regions as the turkey buzzard (or just buzzard), and in some areas of the Caribbean as the John crow or carrion crow, is the most widespread of the New World vultures. One of three species in the genus Cathartes, in the family Cathartidae, the Turkey Vulture ranges from southern Canada to the southernmost tip of South America. It inhabits a variety of open and semi-open areas, including subtropical forests, shrublands, pastures, and deserts.
It, like all New World vultures, is not related to the Old World vultures of Europe, Africa, and Asia. It looks nearly identical because of convergent evolution, where natural selection similarly shapes unrelated animals adapting to the same conditions.
The Turkey Vulture is a scavenger and feeds almost exclusively on carrion. It finds its food using its keen eyes and sense of smell, flying low enough to detect the gases produced by the beginnings of the process of decay in dead animals. In flight, it uses thermals to move through the air, flapping its wings infrequently. It roosts in large community groups. Lacking a syrinx—the vocal organ of birds—its only vocalizations are grunts or low hisses. It nests in caves, hollow trees, or thickets. Each year it generally raises two chicks, which it feeds by regurgitation. It has very few natural predators. In the United States, the vulture receives legal protection under the Migratory Bird Treaty Act of 1918.
The Turkey Vulture received its common name from the resemblance of the adult's bald red head and its dark plumage to that of the male Wild Turkey, while the name "vulture" is derived from the Latin word vulturus, meaning "tearer," and is a reference to its feeding habits. The word buzzard is used by North Americans to refer to this bird, yet in the Old World this word refers to members of the genus Buteo. The generic term Cathartes means "purifier" and is the Latinized form from the Greek kathartēs/καθαρτης. The species name, aura, is Latinized from the Native Mexican word for the bird, auroura. The Turkey Vulture was first formally described by Linnaeus as Vultur aura in his Systema Naturae in 1758, and characterised as V. fuscogriseus, remigibus nigris, rostro albo ("brown-gray vulture, with black wings and a white beak"). It is a member of the family Cathartidae, along with the other six species of New World vultures, and included in the genus Cathartes, along with the Greater Yellow-headed Vulture and the Lesser Yellow-headed Vulture. Like other New World vultures, the Turkey Vulture has a diploid chromosome number of 80.
