Feeding possums not only leads to have become accustomed to a dependence but can also change coming down to the ground for Spotlighting for possums As possums are nocturnal animals, the best way to find them at night is to look for their eyeshine with a spotlight. Eyeshine is caused by a membrane, or ‘tapetum’, at the back of the eye which reflects light back through the eye a second time to enhance night vision. The more reflected light — in other words, the brighter the eyeshine — the better the can see at night. Thus our dull red eyeshine, seen in flash photos, reveals our night vision to be inferior to that of the , with its bright white glare.

Six of them — the green, lemuroid, Herbert River and Daintree River ringtails, the coppery brushtail and the long-tailed pygmy possum — are endemic to the Wet Tropics and therefore occur nowhere else. (The long-tailed pygmy possum’s relative in New Guinea is a subspecies.)

Most have at least a white spot on the chest and a white tail tip. Some have a pure white chest and/or belly and some also have white bands on the upper arms. Rare individuals are almost entirely white. A dark individual may be mistaken for a lemuroid ringtail. The best distinguishing features are its tapering tail and pointed face with a ‘Roman’ nose. ‘Herbie’, symbol of the Queensland National Parks and Wildlife Service, is a solitary creature and adults are only seen in pairs before mating. The female gives birth to two young which spend an unusually short time on her back. The mother sometimes ‘parks’ her older babies on branches; these should not be moved as the mother will return to them. Tree hollows, epiphytic ferns or mistletoes are preferred for dens but some animals have The lemuroid is the only one of the been observed to construct nests, all less than two metres from the ground. Like the larger possums to leap in this way. common ringtails, the Herbie carries thin branches in its curled tail and weaves them into It is able to cover distances of a cup-shaped or a domed structure with a side entrance. two to three metres and does so with its legs spread like a glider. In fact, Daintree River ringtail the lemuroid is a ‘half This possum is very similar to the Herbert River ringtail but the pale brown colour of the glider’, having a young ‘Herbie’ is retained by the adult of this species. The two possums have separate rudimentary skin flap on each side of its distributions, the Daintree species occupying an area to the north of the ‘Herbie’s’ body. This is particularly visible in young range. They were recognised as different species only in 1989 on the basis of having ones. different chromosome numbers. The lemuroid characteristically has a round fluffy shape with a short-nosed pug-like face.

Although she has two teats, the female usually gives birth to only one young which stays with her for about 10 months. Coppery This is the largest of the rainforest possums. A sub-species of the common brushtail which is found extensively over Australia, the coppery brushtail is restricted to the uplands of the . Colours vary from grey to yellowish brown to a rich copper, with or without a white tail tip. A grey-coloured animal can easily be confused with the common brushtail but can be identified from its location; if it’s in the rainforest it’s a coppery and if it’s in dry country it’s a common brushtail. If confused with its fellow rainforest dwellers, the ringtails, its ears give it away; brushtails have large triangular ears in contrast to ringtails’ small rounded ones.

Nature notes A diary of natural events creates a pleasing journal which grows richer with the passage of time. Watching for the recurrence of an event after noting it in a previous year, and trying to understand what could have caused changes in timing, is intriguing.

These notes are from the author's own notebook, or were offered by researchers and fellow naturalists. Readers will, inevitably, note variations between their observations and those appearing here. If you do not keep a nature diary perhaps this will inspire you to begin one.

Fruit on the tall, strikingly-buttressed pencil cedar (Palaquium galactoxylum) should ripen this month, following a good flowering in May. The fruit attracts a variety of birds as well as fruit bats. Large enough to fully occupy a teaspoon, pencil cedar fruits are yellow and soft when fully ripe, at which stage they are quite tasty, by bush standards. The seed carries a distinctive longitudinal scar which is typical of the Sapotaceae Dollarbirds, family. (Have a look at the seed of the those strong- next sapodilla you eat.)
