Mammals · Chiroptera · Pteropodidae

Grey-headed Flying Fox

Pteropus poliocephalus

Vulnerable

At high risk of extinction in the wild over the medium term.

Spotted something wrong?

The grey-headed flying fox is the largest bat in Australia, with a wingspan of more than a metre. It is endemic to the eastern strip of the continent and forms daytime colonies of thousands of individuals in trees, increasingly often inside cities such as Sydney and Melbourne. At night it travels tens of kilometres feeding on nectar and fruit, and it is a key pollinator and seed disperser of the eucalypts and the Australian subtropical rainforests. Extreme heatwaves cause mass die-offs.

Fun facts

  • It is an essential pollinator: as it feeds on the nectar of eucalypts and banksias it carries pollen tens of kilometres, far further than any insect, which keeps isolated fragments of forest connected.
  • Heatwaves kill them in their thousands: when the thermometer passes 42 degrees, whole colonies drop out of the trees within a few hours, something that is happening more and more often.
