The mahogany glider (Petaurus gracilis) is an endangered gliding possum native to a small region of coastal Queensland in Australia.


A nocturnal arboreal marsupial, the mahogany glider closely resembles the sugar glider, the squirrel glider and the yellow-bellied glider, but is noticeably larger than any of its relatives (26.5 cm long and 410 g) and has a long tail (34–40 cm). The species gets its common name from its mahogany-brown belly and the similar colour of its patagium, or gliding membrane. The tail is covered in short hair, and is black on the underside.

These gliders are sexually dimorphic, with the males being larger than the females, although the latter usually have a longer tail in proportion to their body. In terms of their body length, females are marginally smaller, measuring 23 to 27 centimetres (9.1 to 10.6 in) compared with the male body length of 23 to 28 centimetres (9.1 to 11.0 in), but they have a slightly longer tail, measuring 35 to 41 centimetres (14 to 16 in) compared with 34 to 41 centimetres (13 to 16 in) in males. However, despite their similar apparent size, the females, at 310 to 454 grams (10.9 to 16.0 oz), are much more lightly built than the males, which weigh between 345 and 500 grams (12.2 and 17.6 oz).

Distribution and habitat

The mahogany glider is restricted to a very small area, between Ollera Creek south of Ingham and Tully in North Queensland, Australia. The habitat consists mainly of open forest with many different flowering plants that provide year-round food.


The mahogany glider has a long breeding season with births starting April and ending in October. Litters consist of one or two young, and are usually born once a year, although a mother can give birth to a second litter if the first is lost before leaving the pouch. The young are weaned at four to five months, and reach sexual maturity at twelve to eighteen months. They have been recorded to live to about five or six years of age.

Each pair of adults shares some of their dens with offspring from the previous breeding season. These dens are marked and defended from other mahogany gliders. The pairs are usually monogamous, although extra-pair matings have been observed.

Behaviour and diet

The mahogany glider eats eucalypt sap and gum, acacia sap and seeds, grass tree sap, pollen, nectar, insects, mistletoe, honeydew, wattle exudates,and at least twenty different tree and shrub species.

It is nocturnal, with adults living together in monogamous pairs. In ideal conditions, the combined home range of a pair of animals averages around 23 hectares (57 acres), although this may be smaller in areas of fragmented habitat. Animals travel a considerable distance each night, with 1.5 kilometres (0.93 mi) being typical; they are generally more mobile in the wet season than in the height of the dry season. During the day, mahogany gliders den in high trees, with poplar gums and forest red gums being especially favoured. Although they are socially monogamous, they do not usually share dens, with each individual having from three to nine dens within its home range.

In January the time spent outside of the den for travelling and feeding is around 40%, while in September the amount was 77%. This activity was spent mostly at night ranging in a continuous period of 8–10 hours outside.

Mahogany gliders have been reported to make deep, nasal grunting sounds when travelling at night, and a similar, but much louder and more rapid, alarm call, which has been described as "reminiscent of a lawnmower". Predators include scrub python, owls, and, in some instances, feral cats.


Mahogany gliders are considered a threatened species due to loss of habitat, with over 80% having been cleared for growing sugar cane, pine trees, and bananas, or for rearing cattle. The mahogany glider's existence has been further endangered by the devastation to the region by Cyclone Yasi on 3 February 2011.

The mahogany glider was lost to science for over a hundred years, from its first description in 1883, until it was rediscovered in 1989. In 2000, Queensland Parks and Wildlife Service enacted a recovery programme for the mahogany glider. The Wildlife Preservation Society of Queensland also has a recovery programme for the preservation of gliders, including the mahogany glider.

Mahogany gliders can be seen in captivity at David Fleay Wildlife Park and Cairns Tropical Zoo, both of which participate in breeding programmes for the mahogany glider.
