Logo: Gliding mammals of the world

The world’s gliding mammals are an extraordinary group of animals that have the ability to glide from tree to tree with seemingly effortless grace. There are more than 60 species of gliding mammals including the flying squirrels from Europe and North America, the scaly-tailed flying squirrels from central Africa and the gliding possums of Australia and New Guinea.

Distribution: Where this species occurs on Borneo it is known from the lower slopes of Gunung Kinabalu (up to 1600 metres), Sandakan and Tawau in Sabah, Sungai Baram in Sarawak, Gunung Liang Kubung in West Kalimantan, and Sungai Kayan in East Kalimantan.

There are records over the lowlands and foothills of most of Borneo. Throughout its distribution it occurs in tall and secondary forests.
