Grey-headed Flying Fox

Pteropus poliocephalus is one of the largest bats in Australia, with a wingspan that can exceed one metre, reddish-brown body fur, and a distinctive grey-furred head from which its common name derives. It is highly social, roosting in large tree-based camps numbering from hundreds to tens of thousands of individuals, and forages at night on nectar, pollen, and fruit from native eucalypts, melaleucas, and rainforest trees. As a wide-ranging pollinator and seed disperser, it plays a critical role in maintaining genetic connectivity across fragmented forest and woodland ecosystems.

The species is endemic to eastern Australia, ranging from Queensland through New South Wales into Victoria and occasionally South Australia. It inhabits subtropical and temperate rainforests, moist lowland forests, woodlands, and increasingly urban and agricultural areas where it forms permanent or seasonal camps.

Populations are declining due to ongoing loss and fragmentation of foraging and roosting habitat from urban expansion and agricultural conversion, more frequent and intense bushfires, and prolonged droughts that reduce food availability. Heat-stress events during extreme temperature spikes cause mass mortality in camps, and conflict with humans over urban roosting and orchard crop damage leads to further losses, alongside disease dynamics affecting colony health.

Conservation efforts include legal protection under Australian national and state legislation, habitat protection and restoration programs, camp management plans balancing human and bat interests, non-lethal crop protection measures, and monitoring through the National Flying-fox Monitoring Program, which tracks population trends across the species' range.

Despite these measures, the population continues to trend downward, and increasing climate variability, extreme heat events, and habitat pressure suggest the species will remain vulnerable without sustained, coordinated conservation action across its range.
