Vulture Feather

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,[2] is the most widespread of the New World vultures.[3] 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.[1] 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.[4] 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.[4] 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.[5] It nests in caves, hollow trees, or thickets. Each year it generally raises two chicks, which it feeds by regurgitation.[6] It has very few natural predators.[7] In the United States, the vulture receives legal protection under the Migratory Bird Treaty Act of 1918.[8]

Habitat:

Distribution and habitat[edit] The Turkey Vulture has a large range, with an estimated global occurrence of 28,000,000 km2 (11,000,000 sq mi). It is the most abundant vulture in the Americas.[3] Its global population is estimated to be 4,500,000 individuals.[1] It is found in open and semi-open areas throughout the Americas from southern Canada to Cape Horn. It is a permanent resident in the southern United States, though northern birds may migrate as far south as South America.[4] The Turkey Vulture is widespread over open country, subtropical forests, shrublands, deserts, and foothills.[37] It is also found in pastures, grasslands, and wetlands.[1] It is most commonly found in relatively open areas which provide nearby woods for nesting and it generally avoids heavily forested areas.[22] This bird with its crow-like aspect gave foot to the naming of the Quebrada de los Cuervos (Crows Ravine) in Uruguay, where they dwell together with the lesser yellow-headed vulture and the black vulture.[38]
