What is the difference between a buzzard and a turkey buzzard?

Vultures are often much larger and darker than hawks are, with a bald (featherless) head. They are not hunters like hawks are, but scavengers, often found circling above a dead or dying animal. Hawks are smaller, built to not only glide and soar like vultures (vultures prefer to soar without flapping much over most hawks), but dive-bomb and fly fast speeds in pursuit of prey such as rodents and birds.
