Grey-headed flying fox Grey-headed flying fox The grey-headed flying fox ("Pteropus poliocephalus") is a megabat native to Australia. The species shares mainland Australia with three other members of the genus "Pteropus": the little red flying fox ("P. scapulatus"), the spectacled flying fox ("P. conspicillatus"), and the black flying fox ("P. alecto"). The grey-headed flying fox is endemic to the south-eastern forested areas of Australia, principally east of the Great Dividing Range. Its range extends approximately from Bundaberg in Queensland to Geelong in Victoria, with outlying colonies in Ingham and Finch Hatton in the north, and in Adelaide in the south. In the southern
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
