S. Papa Skull Replica or King Vulture measures 4.4×2.5×2.5 inches. King Vulture Skull Replica is museum quality polyurethane cast made in USA. 2-part skull (separate cranium and jaw).

The S. Papa or King vulture eats anything from cattle carcasses down to corpses of monkeys and other arboreal mammals to beached fish and dead lizards.

In densely forested areas, mammals likely to be included are many of the abundant sloths whose combined ranges coincide largely with that of this vulture, but elsewhere it has adapted well to domestic livestock.

Principally a carrion eater, there are isolated reports of it killing and eating injured animals, newborn calves, and small lizards. Although it locates food by vision, the role smell has in how it specifically finds carrion has been debated.

Consensus has been that it does not detect odors, and instead follows the smaller turkey and greater yellow-headed vultures, which do have a sense of smell, to a carcass.

In a 1991 study demonstrated that the King vulture could find carrion in the forest without the aid of other vultures, suggesting that it locates food using an olfactory sense.

The S. Papa or King vulture primarily eats carrion found in the forest, though it is known to venture onto nearby savannas in search of food. Once it has found a carcass, the King vulture displaces the other vultures because of its large size and strong bill.

When it is at the same kill as the larger Andean condor, the King vulture always defers to it. Using its bill to tear, it makes the initial cut in a fresh carcass. This allows the smaller, weaker-beaked vultures, which can not open the hide of a carcass, access to the carcass after the King vulture has fed.

The vulture’s tongue is rasp-like, which allows it to pull flesh off of the carcass’s bones. Generally, it only eats the skin and harder parts of the tissue of its meal. The King vulture has also been recorded eating fallen fruit of the moriche palm when carrion is scarce in Bolívar state, Venezuela.

The reproductive behavior of the S. Papa or King vulture in the wild is poorly known, and much knowledge has been gained from observing birds in captivity, particularly at the Paris Menagerie.

An adult King vulture sexually matures when it is about four or five years old, with females maturing slightly earlier than males. The birds mainly breed during the dry season.

A King vulture mates for life and generally lays a single unmarked white egg in its nest in a hollow in a tree. To ward off potential predators, the vultures keep their nests foul-smelling.

Both parents incubate the egg for 52 to 58 days before it hatches. If the egg is lost, it will often be replaced after about six weeks.

The parents share incubating and brooding duties until the chick is about a week old, after which they often stand guard rather than brood.

The young S. Papa or King vulture chicks are semi-altricial, they are helpless when born but are covered in downy feathers (truly altricial birds are born naked), and their eyes are open at birth.

Developing quickly, the chicks are fully alert by their second day, able to beg and wriggle around the nest, preen themselves, and peck by their third day.

They start growing their second coat of white down by day 10 and stand on their toes by day 20. From one to three months of age, chicks walk around and explore the vicinity of the nest, and take their first flights at about three months of age.
