General Description

The King Vulture, the most brilliantly colored of the New World vultures, has varying hues ranging from purple and blue to red and orange on its head.  It has a wing span that can be up to six feet, and its beak is more curved than the other species of vultures.  It’s been given the more powerful features to feed upon the toughest animal carcasses, hence the name.  This vulture has a cream or white color on the front of its body and back. About halfway down, it turns into a black color.  It has a head that is red and an orange neck.  Wattles decorate the side of the head and the back of its neck.  Its wings are mostly white with black tips.  The ruff, flight, and tail feathers are grey to black.  From head to tail, this vulture is about 28-32 inches.  An adult King Vulture can weigh from six to ten pounds.  There are no differences between the males and females of this species.  Because of its superior size, vibrant color, and adapted features, this bird has been coined “king.”  Other birds treat it as such.  When the King Vulture flies in, other birds stop feeding and allow it to eat.

Life History/Ecology



This “king” bird inhabits multiple parts of South America ranging to Central America. Both Mexico and Argentina contain the majority of these vultures.  It is usually associated with lowland tropical forests but can also be found in savannas, grasslands, and desert margins.  The vulture prefers to have an open feeding ground where access and quantity to food is plenty.  This is the primary factor in choosing its habitat.



If it’s dead, the “king” wants it.  It has no apparent sense of smell and finds carcasses through the activity of other vultures.  Its curved bill allows it to feed on much larger carcasses than the other vultures.  It consumes carrion whether it is rotten or fresh.  The ability to eat this without becoming ill makes this vulture a necessity to the balance of nature.  King Vultures are scavengers and are not known to kill any animals, not even ones on the verge of death.


Depending on the location, breeding season varies among the King Vultures.  The vultures court each other loudly by whistling, wheezing, snorting, hissing, flapping wings, and circling each other.  After mating, the female lays one white egg in a chosen hollow tree stump or less likely on a tree above ground.  The male and female both take turns taking care of the egg for about two months or until it hatches.  The male vulture brings back regurgitated carrion for both the female and the new hatchling.  At the young stages, the hatchling eats out of the male’s beak, but later on, the male leaves the regurgitated carrion on the ground.  Nearly three months after birth, the new vulture has all of its flight feathers and can fly from the hollow stump. It remains dependent on its parents for eight months and may stay close for another two years.  When it is three to four years old, it has developed all of its feathers, plumage, and features.


The King Vulture is seldom seen in large groups and usually visits carcasses in a pair or with its single offspring where they easily dominate the smaller vultures.  When it is not resting in a tall canopy, it travels at high altitudes searching for food.  Because they are so mighty, King Vultures often follow other birds towards carcasses and then scare the birds away.  They are not migratory and are seen in the same areas all year long.


A study was conducted in 1986 in hopes to prevent further reduction in King Vultures in the wild because these vultures were either feeding on the road or were not feeding at all.  The research was started by teaching an eight month old King Vulture behavioral feeding and spotting techniques.  While raised in captivity, the vulture was allowed to watch other birds feed on carrion.  As the young King Vulture learned, it was given more freedom.  The captivated King Vultures were let out into the wild after training, and the research became a success, resulting in higher prevention of reduction.

Economic/Ecological Service

It cites III status in Honduras but is not globally threatened.  King Vultures face no serious threat other than deforestation.  As stated above, the King Vulture does nature a great service by recycling nutrients and energy from carrion and carcasses when very few other living things are able to.  They are appreciated in artwork due to their colors.
