...KING VULTURE The most noticeable difference between king vultures and other vultures is that they are largely covered with white plumage. Their wings are mostly white with black tips. The ruff, flight and tail feathers are gray to black; the black areas have an almost opalescent sheen. Their wingspan is between 180 to 198 cm (71 to 78 inches), and from head to tail they are about 71 to 81 cm (28 to 32 inches). An adult can weigh from 3 kg (6.6lbs) up to more than 4.5 kg (9.9lbs). Their bare head, neck, beak and muttle are red, orange and yellow, with very striking eyes that are straw, white or silver in color. Their beaks have a hooked tip and cutting edges, which are very strong. Their feet are gray. These birds are very striking, especially since most other vultures are all black. There are no differences between the males and females of this species. When they are young, king vultures are covered with white downy feathers. Source: http://animaldiversity.ummz.umich.edu
