In the 2000 Red Data Book, two species were classified as "Regionally Extinct"

The two "Regionally Extinct" species are the Egyptian Vulture - Neophron percnopterus - and the African Skimmer - Rynchops flavirostris.

Occasional sightings of both species as vagrants hold out some hope that they will recolonize South Africa. 

The Egyptian Vulture is widely distributed from south western Europe and Africa to southern Asia and is classified as Endangered.

The African Skimmer live on big tropical rivers with sandbanks, lakeshores, and coastal lagoons. The African Skimmer is uncommonly seen in East Africa and is classified in Africa as Near Threatened.
