Black Vulture
Coragyps atratus
Abundant in the southeast, scarce in the southwest is this broad-winged scavenger. In low flight, it proceeds with several quick flaps followed by a flat-winged glide; when rising thermals provide good lift, it soars very high above the ground. Usually seen in flocks. Shorter wings and tail make it appear smaller than Turkey Vulture, but looks are deceptive: body size is about the same, and aggressive Black Vultures often drive Turkey Vultures away from food.
Conservation status: Has expanded range northward in the northeast, but has declined in parts of southeast. Loss of good nest sites (in large tree hollows) may be one cause.
Family:
New World Vultures
Habitat: Open country; avoids higher mountains. Mostly found in flat lowlands, such as coastal plain. Forages over open country, but typically roosts and nests in forest, so is scarce in open plains. In Latin America, often common around cities and towns. Less likely than Turkey Vulture to fly over open water, so absent on many islands (such as Florida Keys).
