lybica) and, more rarely, the cheetah (Acinonyx jubatus), as well as several canine species, including the golden jackal (Canis aureus), fennec fox (Vulpes zerda) and Rüppell's fox (Vulpes rueppellii). The striped hyena (Hyaena hyaena) may also occupy the range. African wild dogs (Lycaon pictus) formerly roamed the range, although these populations are now extirpated. Olive baboons (Papio anubis), found as recently as 1960, are now likely extirpated as well. Bats are heavily represented in the Tibesti, including the Egyptian mouse-tailed bat (Rhinopoma cystops), Egyptian slit-faced bat (Nycteris thebaica) and the trident bat (Asellia tridens). The Cape hare (Lepus capensis) and the rock hyrax (Procavia capensis) also populate the area. Reptiles and amphibians, on the other hand, are sparse. Snake species include the braid snake (Platyceps rhodorachis syn. Coluber rhodorachis) and the long-nosed worm snake (Myriopholis macrorhyncha syn. Leptotyphlops macrorhynchus). Among the lizards are Bibron's agama (Agama impalearis), the ringed wall gecko (Tarentola annularis) and the Sudan mastigure (Uromastyx dispar). Mid-20th-century herpetological studies noted the presence of brown frogs (Rana sp.) and true toads (Bufo sp.). Many resident birds can be found in the Tibesti. These include the crowned sandgrouse (Pterocles coronatus), bar-tailed lark (Ammomanes cincturus), blackstart (Oenanthe melanura syn. Cercomela melanura), desert lark (Ammomanes deserti), desert sparrow (Passer simplex), fulvous babbler (Argya fulva), greater hoopoe-lark (Alaemon alaudipes), Lichtenstein's sandgrouse (Pterocles lichtensteinii), pale crag martin (Ptyonoprogne obsoleta), trumpeter finch (Bucanetes githagineus) and the white-crowned wheatear (Oenanthe leucopyga). The gueltas are flushed periodically each year by stormwater, maintaining low salinity and supporting several species of freshwater fish. These include the African sharptooth catfish (Clarias gariepinus), East African red-finned barb (Enteromius apleurogramma syn. Barbus apleurogramma), Tibesti labeo (Labeo tibestii, an endemic species) and the redbelly tilapia (Coptodon zillii). Population The town of Bardaï, located on the northern flank of the mountains at an elevation of , is the capital of the Tibesti region. It is connected to the town of Zouar, to the southwest, by a track that crosses Tarso Toussidé. The village of Omchi is accessible from Bardaï via Aderké, or from the town of Aouzou via Irbi. These rough tracks extend southward towards Yebbi Souma and Yebbi Bou, and then follow the course of Enneri Misky. The eastern half of the Tibesti is cut off from the western half, and the eastern village of Aozi is accessible from Libya via Ouri. Zouar has an airport, as does Bardaï at Zougra. Bardaï
