Yellow-Bellied Glider

Petaurus australis

The yellow-bellied glider (Petaurus australis) is a large gliding possum of eastern Australia, found in mature eucalypt forest from Queensland into Victoria. It is much bigger and louder than the familiar sugar glider, with gray-brown upperparts, a pale to yellowish belly, a long blackish tail, and a gliding membrane stretching from wrist to ankle. Nocturnal groups den in tree hollows and announce themselves with drawn-out shrieks that carry through forest at night. A useful field sign is the repeated V-shaped cuts they make in selected eucalypts to lap sap, alongside feeding on nectar, pollen, honeydew, and insects.

This is mainly a wildlife-care, survey, and conservation species rather than a conventional pet; possession generally requires native wildlife authorization in Australia. Management depends on keeping tall, connected forest with old hollow-bearing trees and reliable sap-feed trees, so logging, intense fire, and fragmentation can remove both shelter and food. Rehabilitation or zoo care calls for vertical space, dark nest boxes, branches for climbing and gliding practice, a specialized nectar-gum-insect diet, and quiet handling to limit stress. Nest-box programs and call surveys are sometimes used where natural hollows are scarce or populations need monitoring.
