context_page_description: The king vulture is a large bird found in Central and South America. It is a member of the New World vulture family Cathartidae. This vulture lives predominantly in tropical lowland forests stretching from southern Mexico to northern Argentina. It is the only surviving member of the genus Sarcoramphus, although fossil members are known.
  Large and predominantly white, the king vulture has gray to black ruff, flight, and tail feathers. The head and neck are bald, with the skin color varying, including yellow, orange, blue, purple, and red. The king vulture has a very noticeable orange fleshy caruncle on its beak. This vulture is a scavenger and it often makes the initial cut into a fresh carcass. It also displaces smaller New World vulture species from a carcass. King vultures have been known to live for up to 30 years in captivity.
  King vultures were popular figures in the Mayan codices as well as in local folklore and medicine. Although currently listed as least concern by the IUCN, they are decreasing in number, due primarily to habitat loss.
context_section_description: The king vulture soars for hours effortlessly, only flapping its wings infrequently. While in flight, its wings are held flat with slightly raised tips, and from a distance the vulture can appear to be headless while in flight. Its wing beats are deep and strong. Birds have been observed engaging in tandem flight on two occasions in Venezuela by naturalist Marsha Schlee, who has proposed it could be a part of courtship behaviour.
  Despite its size and gaudy coloration, this vulture is quite inconspicuous when it is perched in trees. While perched, it holds its head lowered and thrust forward. It is non-migratory and, unlike the turkey, lesser yellow-headed and American black vulture, it generally lives alone or in small family groups. Groups of up to 12 birds have been observed bathing and drinking in a pool above a waterfall in Belize. One or two birds generally descend to feed at a carcass, although occasionally up to ten or so may gather if there is significant amount of food. King vultures have lived up to 30 years in captivity, though a male transferred from the Sacramento Zoo to the Queens Zoo is over 47 years old. Their lifespan in the wild is unknown. This vulture uses urohidrosis, defecating on its legs, to lower its body temperature. Despite its bill and large size, it is relatively unaggressive at a kill. The king vulture lacks a voice box, although it can make low croaking noises and wheezing sounds in courtship, and bill-snapping noises when threatened. Its only natural predators are snakes, which will prey upon the vulture's eggs and young, and large cats such as jaguars, which may surprise and kill an adult vulture at a carcass.
