The most widely distributed vulture in the New World, the Turkey Vulture is a large, predominantly blackish-brown bird. It is most commonly seen soaring overhead. The Turkey Vulture has a 5- to 6-foot wingspan and soars with its wings tilted up, in a dihedral pattern. Turkey Vultures rock back and forth when soaring. The underwings are two-toned: silvery flight feathers with black wing-linings. The undertail is also light. Juveniles have gray heads while newly hatched birds have black heads. When the birds are soaring, it is difficult to see the color of the head. The rocking, as well as the dihedral pattern, distinguishes the Turkey Vulture in flight from other large, soaring birds. Perched, adult Turkey Vultures are unmistakable, with their featherless, red heads.
