IN THE BLACK of night time, Australia’s 27 species of possum and glider scamper across our roofs, dart alongside branches in secluded rainforests or peer tentatively from tiny hidey-holes.

Hissing, growling or utterly silent, they carry out a circus act of acrobatic feats, the bigger gliders spreading their gliding membranes to travel greater than 100 m at a single bounce.

Some gliders have even been recorded doing a U-turn in mid-air.

With giant eyes to seize more of the sunshine at night time, they’ve adapted to watch for owls, quolls and pythons, but their largest menace – humankind – has increasingly encroached on their territory, destroying old-growth forest and its sheltering, century-old treehollow

Furry, cuddly and typically curious, possums and gliders are amongst Australia’s best-loved residents and a captivating function of night-life within the bush.

Mahogany glider

Petaurus gracilis
