Jelaskan Ecology and behavior dari Nasar Raja dalam bahasa melayu

The King Vulture is an expert glider, sometimes soaring for hours without flapping its wings. While in flight, its wings are held dihedral, or 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. 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. However, it can gather in large groups at a carcass. King Vultures have lived up to 30 years in captivity, though their lifespan in the wild is unknown. This vulture uses urohydrosis, defecating on its legs, in order to lower its body temperature. Despite its bill and large size, it is relatively unaggressive at a kill and will normally back down rather than fight. The King Vulture lacks a voice box, though it can make low croaking noises and wheezing sounds. 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.
