The Aldabra flying fox (Pteropus aldabrensis) is a species of megabat in the genus Pteropus. It is endemic to the Aldabra Atoll in the Seychelles, like Chaerephon pusilla,[2] though the latter may be the same species as the little free-tailed bat.[3]

Taxonomy

The bat was given its scientific name in an 1893 publication by Frederick W. True, an American biologist and curator at the United States National Museum (now part of the Smithsonian Institution). True based his description of the species on two specimens collected in 1892 by William Louis Abbott, an American doctor and naturalist.[4]

Biology and ecology

Like other megabats, commonly known as fruit bats, the Aldabra flying fox is herbivorous. It has been observed eating fruit from the evergreens Calophyllum inophyllum and Mystroxylon aethiopicum, the Indian almond, and fig trees such as the giant-leaved fig, Ficus rubra, and Ficus reflexa. The bat also eats flowers from the coconut tree and sisal plant and the leaves of the grey mangrove tree. It has been observed licking honeydew produced by scale insects infesting fig trees; rats exhibit the same behavior.[2]

Range and habitat

The natural habitats of the Aldabra flying fox are subtropical or tropical mangrove forests and subtropical or tropical dry shrubland.

Conservation

The species is classified as vulnerable by the IUCN due to a restricted habitat, threats from natural disasters such as tropical cyclones, and rising sea level due to climate change.[5] The biologist A.M. Hutson has described the Aldabra flying fox as "one of the rarest bats in the world" based on a 1968 estimate of a 250-bat total population.[2]
