Fun Facts

  1. There are several theories as to why the king vulture was given its name; one theory suggests it comes from a Mayan legend that believed the vulture to be a messenger between humans and the gods and the vulture was personified as a Lord or King.
  2. How king vultures find their food is a topic many scientists do not agree about.  Some say they rely on their excellent eyesight while others say it is their sense of smell. Some authorities believe the vultures merely follow other scavenging birds to the food.
  3. The king vulture has one of the most powerful beaks of all American vultures and can open carcasses that other vultures cannot. For this reason, they often eat first and other vultures feed off the remains.
  4. The head and neck of a King Vulture are featherless. This helps to prevent bacteria and blood from "fowling" up the feathers on the head.

Ecology and Conservation

The King Vulture is a scavenger and feeds on carrion which could potentially spread disease. They are also able to utilize a food resource that few animals can exploit.

The population is suspected to be in decline due to ongoing habitat destruction
