The vultures have tough skin to keep them warm.
Skills and Adaptations: Some species have adaptations or skills suited to the scavenger way of life. The African white-backed vulture lacks feathers on its long neck. This helps the bird dig deep into a carcass without getting soiled. The small Egyptian vulture, which rarely has a chance when other larger vultures are tearing into a carcass, has learned to use stones to break open ostrich eggs. The Turkey vulture, often called a buzzard, has an acute sense of smell, enabling it to find roadkill before other vultures can beat it to its reward
