carunculated, or with the skin wrinkled; bill, strong, rather lengthened

and strongly hooked; claws, usually moderate, and but slightly curved;

wings, usually long and powerful. Size, generally large; body, heavy.

General structure adapted to the destruction of dead animals

exclusively, but a few species do not hesitate to attack young or feeble

animals when living.

Inhabit the temperate and the warm regions of the earth, but are much

more numerous in the latter. There are about twenty known species of

Vultures.
