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 of 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.
Like all New World vultures, it is not closely related to the Old World vultures of Europe, Africa, and Asia. The two groups strongly resemble each other because of convergent evolution; natural selection often leads to similar body plans in animals that adapt independently 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 gasses 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. [Wikipedia]
If you’ve gone looking for raptors on a clear day, your heart has probably leaped at the sight of a large, soaring bird in the distance– perhaps an eagle or osprey. But if it’s soaring with its wings raised in a V and making wobbly circles, it’s likely a Turkey Vulture. These birds ride thermals in the sky and use their keen sense of smell to find fresh carcasses. They are a consummate scavenger, cleaning up the countryside one bite of their sharply hooked bill at a time, and never mussing a feather on their bald heads. [All About Birds]
- According to Jamaican Folklore, Turkey Vultures or John Crows as they are called, don’t ‘work’ or scavenge on a Sunday.
- If you see Turkey Vultures circling over an area, chances are there is a carcass nearby.
- Some Turkey Vultures are afflicted with Leucism, this condition results in a partial loss of pigment which results in a white or pale coloration.
- The oldest recorded Turkey Vulture was at least 16 years, 10 months old when it was found in Ohio, the same state where it had been banded. [All About Birds]
