Aldabra flying fox The species was 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. 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. Aldabra flying fox 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, though the latter may be the same species as the
Australian flying fox die-offs flying fox ("Pteropus poliocephalus") and the black flying fox ("P. alecto"). Where mixed-species colonies are affected the black flying fox suffers substantially higher mortality than the grey-headed flying fox. However, summer temperatures are more extreme within the range of the grey-headed flying fox than within the range of the black flying-fox, and therefore the actual total number of casualties is much higher among grey-headed flying foxes than black flying foxes. Mortality is especially high among dependent young and lactating females, but any demographic category can be affected. Observations in flying fox colonies during extreme heat events have revealed that flying
