Koalas are mainly tree-dwelling and may eat up to 2 kilograms of leaves a day. The tree kangaroo of the Queensland rainforest uses trees in the same way as possums, browsing on trees leaves and fruits rather than grass. They are good climbers and are the only kangaroos which move each hind leg independently. Other unusual tree dwellers are the native tree-rats which occur in tropical northern Australia and feed and nest in forest trees such as palms. Bats Most bat species roost in trees or caves during the day, and search for food at night.
Some bats consume vast numbers of insects and are valuable pest-controllers.
Gould's Bat eats scarab beetles, crickets, moths and caterpillars. Seeds pass through the gut of flying foxes very quickly, ensuring that the seeds remain viable. The sugar glider is a common and wide spread mammal which feeds on insects like scarabs, weevils, lerp and scale insects and caterpillars. Sugar gliders also feed on nectar, and, especially in winter, on gum exuded by wattles. They sleep and nest in tree hollows.
