The Black vulture (Coragyps atratus), is also known as the American black vulture. Its range extends from the south-eastern United States to Central Chile and Uruguay in South America. The gregarious black vulture roosts, feeds, and soars in groups, often mixed with turkey vultures. As a result of the Turkey Vulture’s acute sense of smell, Black Vultures often follow Turkey Vultures to find food. They are more aggressive than turkey vultures and often drive the latter away from carcasses. If frightened while on the ground, black vultures vomit anything they've just eaten to reduce their weight for a quicker take-off. Black Vultures, which rarely flap in flight, have broad plank-like wings that allow them to soar in small thermals.
