Turkey Vulture

sorry for the blurriness of this photo...
The Turkey Vulture is a scavenger and feeds almost exclusively on carrion.[10] It finds its meals using its keen vision and sense of smell, flying low enough to detect the gasses produced by the beginnings of the process of decay in dead animals.[10] 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.[11] It nests in caves, hollow trees, or thickets. Each year it generally raises two chicks, which it feeds by regurgitation.[12] It has very few natural predators.[13] In the United States of America, the vulture receives legal protection under the Migratory Bird Treaty Act of 1918.[14]
