Rüppell's vulture, also called Rüppell's griffon vulture, named after Eduard Rüppell, is a large bird of prey, mainly native to the Sahel region and East Africa. The current population is decreasing due to loss of habitat, incidental poisoning, and other factors. Known also as Rüppell's griffon, Rueppell's griffon, Rüppell's griffin vulture, Rueppell's vulture and other variants, it is not to be confused with a different species, the griffon vulture. It is considered to be the highest-flying bird, with confirmed evidence of a flight at an altitude of 11 kilometers above sea level. Rüppell's vultures have several adaptations to their diet and are specialized feeders even among the Old World vultures of Africa. They have an especially powerful build and, after the most attractive soft parts of a carcass have been consumed, they will continue with the hide, and even the bones, gorging themselves until they can barely fly. They have backward-pointing spikes on the tongue to help remove meat from bone. Despite their size, power and adaptations, they are not the most dominant vulture in their range, which is considered to be the even larger lappet-faced vulture.
This species of vulture is considered to be monogamous, forming lifelong breeding pairs. After courtship the pair will work together to build a nest using sticks, grass, and leaves that they have gathered or stolen from other nests. Rüppell's vultures build these nests on cliffs, and in key breeding areas they are known to nest in large colonies containing hundreds of breeding pairs. Both parents share in incubation of their egg over a period of 55 days. Once the chick hatches, both parents will feed and tend to it for about 150 days when it fledges. Young remain dependent on their parents after fledging, not reaching independence until the next breeding season. During this time they learn how to find and compete for food.
