Yellow-bellied Glider (Petaurus australis) lives in eastern Australian forests across Eastern Australia. It feeds on eucalyptus sap insects. Its conservation status is Vulnerable.
Fascinating facts about the Yellow-bellied Glider
- The three populations of northern-Queensland gliders, spread across three high-altitude tablelands, hold roughly 6 000 individuals, showing how isolated these groups have become. With altitudes over 700 m and habitats broken by clearings, each tableland hosts a distinct sub-population, making the species vulnerable to local disturbances.
- Weighing between 435 g and 710 g, the yellow-bellied glider is about the size of a rabbit, yet it can live up to six years in the wild, a lifespan comparable to many small mammals. Sexual maturity is reached at roughly two years (about 725 days), after which pairs form monogamous bonds and both parents care for the single offspring. This extended parental investment, including about 100 days in the pouch and another 60 days in the nest.
- The glider's diet is a cocktail of nectar, pollen, insects and the sap of many eucalypt species, which it extracts by carving a V-shaped notch in smooth bark. This feeding habit ties the animal tightly to mature eucalypt trees. When a tree is heavily used, the bark becomes scarred, indicating the glider's impact on forest health. Loss of these old, sap-rich trees through logging directly threatens the glider's food supply and nesting sites.
- Gliding up to 150 m, the yellow-bellied glider can cover a distance longer than a football field in a single leap, yet it also has been observed to jump as far as 114 m. Its long, prehensile tail (up to 48 cm).
- From a single call, a yellow-bellied glider can be heard up to 500 m away, making it the most vocal of its gliding relatives.

About the Yellow-bellied Glider
In the moonlit eucalyptus forests of eastern Australia, a whispered rustle of leaves heralds the nocturnal wanderings of the yellow-bellied glider, its large, round eyes shining like lanterns as it flits effortlessly from branch to branch. With a membrane stretching from wrist to ankle, this remarkable marsupial sails through the darkness, its gentle whoops echoing through the trees as it searches for sap and nectar to sustain it. As it glides, its yellow belly glowing like a tiny sun, the yellow-bellied glider embodies the very essence of Australia's mystical night world.
