Rüppell’s Vultures are highly social, roosting, nesting, and gathering to feed in large flocks. They can travel fast at need, cruising at up to 35 kilometres per hour (22 mph), and will fly as far as 150 kilometres (93 mi) from a nest site to find food.
Rüppell’s Vultures commonly fly at altitudes ranging up to 6,000 metres (20,000 ft). The birds have a specialized variant of the hemoglobin alphaD subunit; this protein has a high affinity for oxygen, which allows the species to take up oxygen efficiently despite the low partial pressure in the upper troposphere.A Rüppell’s Vulture was confirmed to have been ingested by a jet engine of an airplane flying over Abidjan, Côte d’Ivoire on November 29, 1973 at an altitude of 11,000 metres (36,100 ft). In August 2010 a Rüppell’s Vulture escaped a bird of prey site in Scotland, prompting warnings to pilots in the area to keep an eye out due to the danger of collision
