Dusky flying fox Dusky flying fox The dusky flying fox ("Pteropus brunneus"), also known as the Percy Island flying fox, is an extinct species of flying fox in the family Pteropodidae. It was endemic to Percy Island off the southeast coast of Mackay, Queensland, in the northeast corner of Australia. Only one specimen is known to exist. It was documented in 1859 and collected by Dobson in 1878. Since that record, no further documentation is known of this species. Currently, the specimen is located at the British Museum of Natural History, and was validated as a separate species in the late 20th century.
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
