Greater Glider

Fascinating facts about the Greater Glider

• A greater glider can stretch its limbs and catch air across 45 metres — nearly the length of four tennis courts — without flapping once. Stretching membrane between their front and back legs acts like a parachute, and their fluffy tail steers like a rudder. They can change direction mid-glide by twisting their body. A single night hunt takes them across 10 to 15 separate flights through the canopy.
• They eat only eucalyptus leaves, but not all species will do — just 2 or 3 preferred kinds out of 600+ varieties. Their stomach is divided into two chambers like a cow's, fermenting leaves slowly to extract maximum nutrition from low-protein foliage. Despite eating all night, they gain so little energy they've evolved to spend 20 hours a day sleeping or resting in tree hollows.
• A greater glider's hearing is tuned to frequencies so high they can detect the wingbeats of insects in the dark. Their ears swivel independently, giving them stereo pinpoint accuracy. This hearing — way beyond human range — lets them hunt moth caterpillars on bark by sound alone while their eyes adjust to night vision.
• They depend entirely on old-growth forest trees with hollows deeper than 10 centimetres — often taking 200+ years to form. A single tree might shelter 10 or more individuals across different hollows, stacked like apartment blocks. Loss of these ancient trees has collapsed populations by up to 80 per cent across eastern Australia since the 1980s.
• Female greater gliders give birth to just one joey per year in a pouch, and the infant stays dependent for 18 months — among the longest childhoods of any gliding mammal. This slow breeding means a population hit by wildfire or logging takes decades to recover. Recent catastrophic bushfires in 2019–2020 burned through core habitat across NSW and Victoria, and scientists still don't know if populations can bounce back.

About the Greater Glider

In the moonlit eucalyptus forests of eastern Australia, the Greater Glider unfurls its silken membrane, a gossamer wing that bears it effortlessly across the shadows, its large, round eyes drinking in the faint light as it searches for the sweet sap and leaves that sustain it. With each gentle glide, this nocturnal marsupial weaves a ghostly path through the trees, its soft, woolly fur a mere whisper against the branches as it moves with an ethereal silence. As it floats, a fleeting shadow, the Greater Glider embodies the very essence of the Australian night, a reminder of the magic that still lurks in the darkest, most forgotten corners of our world.
