A turkey vulture (Cathartes aura) sits on a post at City of Rocks National Reserve in Idaho. An osprey (left) and black vulture (right) close together with their wings out along the shores of the Potomac River in Virginia. Black vultures are more visual hunters than the turkey vultures. Turkey vultures spread their wings, while perched on a tree branch at Capulin Volcano National Monument in New Mexico. While menacing looking, turkey vultures are scavengers that do not kill their prey.
