Turkey Vulture

General Description

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.
Turkey Vultures are Uncommon in Western Washington from March-August Fairly Common September-October.

Habitat

Turkey Vultures can be seen soaring over a broad variety of habitats. They are most often found above open country, especially within a few miles of rocky or wooded areas. Rocky outcroppings, cliffs, and dry forests provide nesting sites, while open areas are prime foraging habitat.

Behavior

Unlike most birds, Turkey Vultures have a well-developed sense of smell. As they soar over foraging areas, they scan the ground, searching for carrion or scavengers that might signal the presence of something dead. When they locate food, they eat it in place. They usually forage alone, but sometimes congregate around food sources. In the Pacific Northwest, they roost communally in small groups. In the eastern US, several thousand birds may nest in the same area.
