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 to Geelong in Victoria, with outlying colonies in Ingham and Finch Hatton in the north, and in Adelaide in the south. In the southern parts of its range it occupies more extreme latitudes than any other ''Pteropus'' species.
==Physical characteristics==
The grey-headed flying fox is the largest bat in Australia. This flying fox has a dark-grey body with a light-grey head and a reddish-brown neck collar of fur. It is unique among bats of the genus ''Pteropus'' in that fur on the legs extends all the way to the ankle. Adults have an average wingspan up to and can weigh up to . The head and body length is between , with an average of . The forearm length is between , with an average of 161 mm. Weight generally varies between , with an average of . It is tailless, with claws on its first and second digits. Since it does not echolocate, it lacks tragus or leaf ornamentation found in most species of Microchiroptera. It relies on sight to locate its food (nectar, pollen and native fruits) and thus has relatively large eyes for a bat.
The grey-headed flying fox is long-lived for a mammal of its size. Individuals reportedly survived in captivity for up to 23 years, and a maximum age of up to 15 years seems possible in the wild.
