The Ruppell’s Griffon Vulture is a large vulture with the adults stretching from 85 – 103cm in length and a wingspan of 2.26 – 2.6m carrying a weight of 6.4 – 9kg. The plumage is black or mottled brown with whitish-brown under parts while the neck and head is covered with a thin dirty-white fluff. The bird features a yellow eye while the base of the neck features a white collar as viewed on birding safaris in Uganda. The Ruppell’s Griffon Vultures are very silent and only vocalize while at their nest or a carcass.
They are notably social bird species and as a result, they roost, nest and gather to feed in large flocks. Their range includes; woodlands, Mountains and grasslands and can stretch up to 150km from their nests in search of food. Their flight to higher altitudes is supported by their haemoglobin alpha that has great affinity for oxygen which enables them to absorb oxygen despite the upper troposphere’s low partial pressure.
The Ruppell’s Vultures are specialised feeders with very strong build which enables them to consume even the hide and bones of the carcass after the soft parts have been finished. Their tongue features back-ward pointing spikes that enable them to extract meat from the bone.
