Pseudocheirus peregrinus
Description
The ringtail possum is an arboreal and nocturnal marsupial, smaller than the more recognised brushtail possum. Adult ringtail possums weigh 800 to 1000 grams. They are usually grey furred on the back and sides, with cream or pale grey underneath. The distinctive tail is long and thin, the last third of it being cream coloured.
Distribution
The ringtail possum prefers to live in dense lower storey vegetation and is quite common in parts of Sydney - particularly the northern districts and northern beaches - although not seen regularly because of its shy nature. It rarely becomes a 'nuisance' in the urban environment, as it usually stays clear of buildings and people.
Habits and Habitat
Ringtail possums build nests called dreys in the more dense foliage of trees. These dreys are similar to large birds' nests but are covered by a 'roof' of leaves and twigs. The possums are sociable animals; they live in groups, often up to 4 animals will be in one drey. However the group's territory may cover several hectares and in that area there may be a number of dreys - all used at various times.
Ringtail possums prefer to eat the fresh new growth leaves in trees - common natives such as eucalypts, melaleucas, tea-trees, and grevilleas. They do like some fruits and flowers also. They rarely drink water - getting enough from the moisture in the leaves. Normally a ringtail possum will have twins or triplets, and often breed twice a year. Babies are usually fairly independent by 5 to 6 months of age, or 300 to 400 grams. Up to about 80 grams they will remain in the pouch. Following this they will cling to the mother's back and travel around with her until independent.
