>For other uses, see Vulture (disambiguation). Vultures are scavenging birds, feeding mostly from carcasses of dead animals. Vultures are found in every continent but Antarctica and Oceania.A particular characteristic of many vultures is a bald head, devoid of feathers. This is likely because a feathered head would become spattered with blood and other fluids, and thus be difficult to keep clean.
