The yellow-bellied glider, scientific name Petaurus australis, also referred to like the fluffy glider, is an arboreal and nocturnal gliding possum that lives in native eucalypt forests in eastern Australia, from northern Queensland south to Victoria.
Yellow-Bellied Glider Profile
Yellow-Bellied Glider lives in coastal and open foothill forest and woodland, and in moist eucalypt forests. In eastern Australia, it lives solely in tall, mature eucalypt forests in areas of high rainfall, with temperate to subtropical climates.
The northern Queensland inhabitants live in forests at high altitudes with decrease temperatures. It happens within the best numbers in coastal and foothill forests and woodland, and in lesser numbers in moist eucalypt forests.
Winter flowering eucalypts (e.g. Eucalyptus maculata) could also be necessary for habitat desire in southern Queensland. High densities seen in New South Wales might correlate to a steady provide of nectar attributable to a better variety of eucalypts.
Mating has been noticed whereas pairs have been clinging to the underside of a branch. Females have two nipples within the incompletely divided pouch. Typically, females bear a single younger, though twins have been noticed.
Breeding is restricted to August by December in Victoria however happens all through the year in Queensland. Young are carried within the mom’s pouch for about 100 days, after which era they’re left in a nest for an extra 60 days.
Both parents present to look after the younger, which change into impartial after 18 to 24 months, and change into sexually mature at about 2 years of age.
Yellow-Bellied Glider is a particularly lively, arboreal, nocturnal glider. Researchers have recorded glide distances as much as 114 meters. P. australis is essentially the most vocal of the gliders and infrequently lets out a loud call because it glides.
It usually carries its tail in a vertically erect method, just like felids. P. australis is territorial and aggressive to intruders of identical species.
It is social to some extent, residing in small family teams of 1 adult male and 1 or two females with their offspring. It usually constructs a leaf-lined nest in a hole tree during which it sleeps throughout the day.
Yellow-Bellied Glider happens in native eucalypt forests alongside the eastern and southeastern coasts of Australia in Queensland, New South Wales, and Victoria.
It ranges inland as a lot as a number of hundred kilometers and has an in-depth, however patchy distribution.
It is mostly present in low densities and regarded uncommon all through most of its range, though it may be domestically widespread (e.g. as in east Gippsland).

Yellow-Bellied Glider Habitat
The yellow-bellied glider inhabits forests and woodlands in eastern Australia and is discovered at a range of altitudes from sea level to 1400 meters.
In North Queensland, the sub-species happen at altitudes over 700 m above sea level. With natural discontinuities and habitat clearings, there are 13 totally different populations in three distinct locations to search out this glider in North Queensland.
One inhabitant resides on Mount Windsor Tableland, one other on Mount Carbine Tableland, and the third lives in a linear habitat going from Atherton to Kirrama on the Atherton Tableland.
These three populations collectively are estimated to comprise around 6000 particular person gliders. With their habitat at risk, the yellow-bellied glider is assessed as unusual to uncommon and is called weak to the tropics. This species is more widespread in southern Queensland, NSW, and Victoria.
Yellow-Bellied Glider Physical Description
Body size in Petaurus australis ranges from 27 to 30 cm, and tail size ranges from 42 to 48 cm. Its pouch has two incompletely divided compartments divided by a well-developed septum, a function distinctive amongst marsupials.
The fur is ok and silky. Its tail is prehensile and totally lined in fur. Its coloration is dusky gray-brown dorsally and creamy to yellowish-orange ventrally, with black feet and an indirect darkish strip on its thigh.
It has semi-naked ears and a pink nostril. A gliding membrane is related to its wrists and ankles. Males are bigger than females.
Yellow-Bellied Glider Appearance and behavior
The yellow-bellied glider is a marsupial in regards to the size of a rabbit. It usually has grey-brown fur on its back and has an off-white to orange or yellow stomach.
It has massive pointed ears and a long tail that may develop to succeed in 48 cm in size.
Its body size is smaller reaching about 30 cm long and the marsupial weighs a total of 700 g. The males are normally greater than the females.
There are two subspecies:
P. a. australis within the south (which is domestically widespread)
P. a. reginae in northern Queensland (which is uncommon and threatened with logging)
The yellow-bellied glider is the most important species of Petaurus, the wrist-winged gliders, a gaggle of arboreal marsupials, and may glide as much as 150 m. The yellow-bellied glider has been noticed to leap as much as 100 m or 114 m.
It is comparable in look to the mahogany glider, though barely bigger in size. It can be related in look to the better glider, a species that’s more carefully associated with the lemur-like ringtail possum than to the opposite members of the genus Petaurus.
The yellow-bellied glider is gregarious and spends the day in a leaf-lined tree gap, which is normally shared with different members of the identical family.
It can be one of the vocal possum gliders. It has a particular growling call that it makes use of as a technique of communication. It has been recorded to have been heard as much as 500m away.
Yellow-Bellied Glider Food Habits
The diet of Petaurus australis consists largely of nectar, pollen, and the sap of eucalypts. The sap is obtained by incising the bark on the higher branches and trunks of Eucalyptus resinifera timber and ingesting the ooze. Some particular person timber is clearly favored and change into very closely scarred. Its diet additionally contains bugs, arachnids, grubs, and probably small vertebrates.
Yellow-Bellied Glider Reproduction
Breeding happens in spring within the south, however all through the year in Queensland within the north. Sexual maturity for the glider is around two years of age when the glider will then pair up with one other glider, normally in a monogamous relationship, and mate August to December.
The offspring are usually born between May and September.
They then keep within the marsupium for about 100 days. The younger are then left within the den for two-three months before they’re weaned from the mom and go off on their very own. While within the dens each parent will look after the offspring.
In North Queensland, the dens are made in Eucalyptus grandis timber and are lined with leaves. Their total life expectancy is about six years.
The yellow-bellied glider’s diet consists of nectar, honeydew, bugs, pollen, and a widespread of tree sap together with totally different Eucalyptus sap, Corymbia sap, some Angophora sap, and Lophostemon sap.
It reveals a robust desire for timber with clean bark, probably regarding the quantity of sap circulation. It obtains the tree sap by biting a ‘V’ form wedge/notch into the bark to advertise the circulation of gum and sap. It normally incises the bark on the trunks or higher branches of the timber.
Habitat loss and fragmentation attributable to timber-harvesting and agriculture are the primary threats to this species. The earlier feeling of old nest timber along with regular proscribed fireplace regimes and normal timber elimination has led to a degradation of the remaining habitats.
Previously it had been listed as a species of “Least Concern” due to its extensive distribution, together with a number of protected areas. This itemizing was modified to “Near Threatened” within the 2016 IUCN Red List publication due to a population lower of 30% over three generations.
Since Petaurus australis is strongly tied to sure species of eucalypt timber, elimination or harm to those timber ends in habitat discount. Eucalypt forests in Australia are reduced for timber or cleared for agricultural functions.
It can be obvious that the elimination of old-growth components from unlogged forests or from beforehand lightly-logged forests ends in a decline within the density of those animals.
Because the species requires quite a lot of timber to feed on in blended forests over massive house ranges, and since it wants hole timber for nesting, its conservation requires the preservation of enormous tracts of forests.
