The Egyptian vulture, a new addition to IUCN's 2007 Red List, has declined along with many other vulture species.
Five species of vulture, including the Egyptian, have been reclassified to a higher threat level since 2006. Asian vultures have declined rapidly over the last eight years due to the use of a livestock drug called diclofenac.
African vultures are struggling due to habitat loss, a lack of food, and collisions with power lines.
The scavengers are also being killed by insecticide-laden carcasses, which have been deliberately baited to poison livestock predators such as hyenas.
