King Vultures are distinguished from other vultures by their colourful looks. Their feathers are mostly white, with some black, they have very pale blue eyes and their heads and necks can be many colours. These head and neck colours can change depending on mood and include yellow, red, orange, purple and blue. They are the largest new world vulture, excluding the condors. They may have been named “King” vultures as they often displace smaller vultures at a carcass, and won’t let smaller vultures eat until they have had their full. Another possible cause for this name is Mayan legend that these vultures were kings, and messengers between humans and the gods.
