This is so that bits of carrion dead meat do not adhere to the skin as they would to feathers. They are more visual hunters than the turkey vulture and often watch the latter from above while it hunts by scent. Once food carrion is located, the black vulture, being more aggressive, often drives away the turkey vulture from its newly found meal. They can smell carrion only hours old.
