Description

A nocturnal mammal, very similar to the more common and smaller Sugar Glider. However, the Squirrel Glider has a longer more pointed face, longer and narrower ears and a bushier tail. Fur is blue-grey to brown-grey above and white or cream below. A distinctive dark mid-dorsal stripe which extends from between the eyes to the mid back. Tail is bushy and is covered with grey to black fur. Vocalisation is a deep and throaty gurgling chatter.

Distribution

Occurs in eastern Australia extending from north eastern Queensland through eastern NSW and down through northern and central Victoria. The endangered population is within the Pittwater Local Government Area on the Barrenjoey Peninsula, north of Bushrangers Hill.

Habitat and ecology

  • NSW: occurs on the coast in a range of habitats including low scrubby eucalypt woodlands and banksia thickets to tall, wet eucalypt forests bordering on rainforest .
  • The availability of a year-round supply of carbohydrates (nectar, sap, gum, and honeydew) appears to be an important habitat feature. In NSW, this corresponds to a high diversity of tree and shrub species, including a high nectar producing species and one or more winter flowering species.
  • In Pittwater, important food sources are likely to be the winter flowering Coast Banksia (Banksia integrifolia) and Spotted Gum (Corymbia maculata) and the summer flowering Old Man Banksia (B. serrata) and Grey Ironbark (Eucalyptus paniculata). Other likely food sources include Angophora costata, Banksia spinulosa, Corymbia gummifera, Eucalyptus botryoides, E. punctata, E. robusta, Melaleuca quinquernervia, mistletoes and Xanthorrhoea species.
  • This animal will gouge and lick incisions on the trunks and main branches of Eucalyptus, Corymbia and Angophora trees to feed on sap and on Acacia trees and shrubs to feed on gum, especially when nectar is in short supply.
  • Tree hollows are an important habitat feature providing den sites for raising young. Hollows can be found in trees of the following genera Eucalyptus, Corymbia and Angophora. Other species such as Melaleuca quinquenervia can also provide suitable hollows.
  • A family group consists of 2-9 individuals, one male and at least two adult females and their dependent offspring, which shelter by day and breed in leaf lined nests in tree hollows. Litter size is one to two and the young remain in the pouch for about 70 days, after which they stay in the nest for another 30 days, and are weaned at four months.
  • Births may occur throughout the year, usually with peak in winter. Most females exhibit the capacity to raise two litters per year. Young gliders disperse at a mean age of 12.5 months.
