North Queensland Naturalist

Abstract

In north Queensland, the Yellow-bellied Glider (Petaurus australis) makes incisions in the bark of Eucalyptus resinifera (Small-fruited Red Mahogany) to access the sap that flows from these cuts. It is known that other bird and mammal species feed at these incisions including the Spectacled Flying-fox (Pteropus conspicillatus), but there is no published record of Little Red Flying-fox (Pteropus scapulatus) doing the same. Here we report observations of Little Red Flying-foxes feeding on this sap and provide evidence of agonistic interspecific interactions between it and the Yellow-bellied Glider at a sap-tree.
