Common Ringtail Possum: Australian species guide

Pseudocheirus peregrinus

Database risk label: LOW
Location: Eastern Australia
Database size: 30-35cm + tail

The Common Ringtail Possum is a native Australian, tree-dwelling marsupial. It is also called the Eastern Ringtail Possum by the Australian Museum. This page is about the species Pseudocheirus peregrinus—not every ringtail possum, and not the similarly familiar Common Brushtail Possum. The Atlas of Living Australia lists Pseudocheirus peregrinus as an accepted species name, in the family Pseudocheiridae. [1]

WildGuardian record: ID 26 · Mammal · Risk label: LOW

A ringtail is a characteristic night visitor in well-treed suburbs as well as in natural vegetation. Its white-tipped gripping tail, rounded ears and preference for leafy cover are useful clues, but a photo alone may not settle every identification. The best response to a sighting is usually to give the animal space and enjoy the observation from a distance.

Identification: useful clues, not a guarantee

An adult Common Ringtail Possum is a small-to-medium possum with a grey to grey-brown back, pale underside, short rounded ears and often a white patch behind each ear. Rusty or orange-brown tones can show on the limbs and tail. Its long, prehensile tail has a white tip; the upper side is furred and the underside towards the tip is bare. The tail is used to grip branches and is often curled when the possum is at rest. [2] [3]

Size can help when the animal is clearly seen, but it is not the first feature to rely on at night. Victorian government guidance gives a body length of about 30–35 cm, with a tail of roughly similar length; the Australian Museum gives the same body and tail range. [2] [3] A Common Ringtail is considerably smaller than a Common Brushtail Possum. Victorian guidance describes the ringtail as about half the size of a cat, while a brushtail is about cat-sized. [6]

The tail is a more useful field mark than coat colour. The Australian Museum notes that a ringtail’s white-tipped, furred-above, bare-below tail is used to grip branches; by contrast, a Black Rat has a long, sparsely haired, scaly tail that is not used for gripping. [5] Even so, juvenile rodents can be very difficult to identify from photographs, and the Museum cautions that photographic rat identifications can be unreliable. [5] Treat a distant, dark, juvenile or obscured sighting as unconfirmed rather than forcing a species name.

Australian range and habitat

The Common Ringtail Possum occurs across eastern Australia, with populations also recorded in Tasmania and south-western Western Australia. [3] In New South Wales it occurs through eastern parts of the state, where NSW National Parks and Wildlife Service describes it as a common nocturnal animal of forests and gardens. [4] The Australian Museum likewise places it predominantly in Queensland, New South Wales, Victoria, Tasmania and South Australia. [2]

It is an arboreal species: that is, it lives mostly in trees. Recognised habitats include rainforest, eucalypt forest, woodland, dense scrub and leafy suburban gardens. [2] [3] Suburbs can therefore be genuine ringtail habitat when they retain connected vegetation, rather than simply places an animal passes through. NSW National Parks and Wildlife Service notes that its tail and claws support movement and foraging in trees. [4]

During the day, ringtails rest in a rounded nest called a drey. Australian Museum guidance describes dreys made from grass and shredded bark in a tree hollow, tree fork or dense vegetation; more than one animal may share a nest. [2] NSW National Parks and Wildlife Service similarly describes spherical nests lined with moss, shredded bark and grasses, with family groups sometimes using communal nests close together. [4] A leafy sphere high in vegetation is a reason to observe carefully from below, not a reason to disturb it.

Behaviour and ecology

Common Ringtail Possums are nocturnal. They forage after dark, taking leaves—especially eucalypt leaves—along with flowers and fruit. [3] [4] The Australian Museum records that they eat leaves from native and introduced plants as well as flowers and fruits. [2] This leaf-rich diet helps explain why sightings are often in canopies, dense shrubs and gardens with mature vegetation.

They have a specialised way of getting nutrition from leafy food: they re-ingest faecal pellets, allowing food to be digested twice. [2] [3] This is an ecological detail, not a sign that an animal is ill.

Ringtail family life can be conspicuous when a young animal rides on an adult’s back. The Australian Museum reports male care of young, including males carrying young while the mother feeds, and notes that this is the only possum species currently known to show this form of male care. [2] Victorian guidance also describes both parents caring for young and records communal foraging and nesting by family groups. [3]

The species faces risks in built landscapes. The Victorian fact sheet identifies predation by Powerful Owls in trees, vulnerability to foxes and unconfined cats and dogs on the ground, deaths from powerlines, and urban development as pressures. [3] These are broad conservation and welfare concerns, not a basis for trying to intervene in an individual animal without professional guidance.

Safer encounters around homes and gardens

A ringtail seen moving along branches, fences or overhead lines after dark is behaving as a climbing, nocturnal possum normally does. [2] [4] Keep viewing low-key: remain back, avoid cornering the animal and keep children and pets from approaching. Direct contact is unnecessary for identification and can create a stressful encounter for both animal and person.

Do not offer human food. Victorian wildlife guidance states that human food can be dangerous to possums and cause serious dietary imbalance. [6] It is also sensible to leave a drey, adult and young undisturbed. These animals depend on their resting places and familiar vegetation; NSW National Parks and Wildlife Service says family groups can become attached to nest sites. [4]

If you encounter a possum that appears sick, injured, orphaned or unable to move away, do not touch it. Victorian government guidance for possums and gliders says they may carry diseases transferable to people and should only be handled by a trained rescuer; the service provides wildlife-carer contacts for Victoria. [7] Elsewhere in Australia, contact the relevant state or territory wildlife agency or an authorised local wildlife rescue service for current, place-specific advice. Rules and services vary by jurisdiction. For example, Victoria protects possums under its Wildlife Act and says it is illegal to harass or interfere with them; this is Victorian, not Australia-wide, legal information. [6]

Medical response if skin is broken

This species page does not use snake- or spider-bite advice. The practical health issue is an ordinary wound if teeth or claws break the skin. Healthdirect says a wound from an animal bite should be assessed by a doctor or nurse within 2 to 6 hours. [8]

For a minor wound, Healthdirect advises stopping bleeding with pressure, cleaning it with clean water or saline, and covering it with a non-stick dressing where possible. Seek urgent help for severe bleeding, a wound in the eye, faintness, chest pain, shortness of breath or loss of consciousness. [8] Medical assessment is also appropriate if the wound becomes more painful, red, swollen, hot, oozes pus, does not heal, or if tetanus vaccination status is uncertain. [8] For urgent medical help in Australia, call Triple Zero (000); for non-emergency health advice, Healthdirect lists 1800 022 222. [8]

Frequently asked questions

Is a Common Ringtail Possum the same as a Common Brushtail Possum?

No. They are different species. The Common Ringtail Possum is smaller and has a slender, white-tipped prehensile tail; the Common Brushtail Possum is larger, with a bushier tail. [6]

Where am I most likely to see one?

Look after dark in tree cover, dense shrubs, woodland, forest or leafy gardens within the species’ Australian range. It sleeps by day in a drey or other sheltered vegetation structure. [2] [3]

Could the animal in my photo be a rat instead?

Possibly, especially if the animal is small, young or poorly lit. A white-tipped tail used to grip branches is a strong ringtail clue, while the Black Rat’s tail is scaly, sparsely haired and not used to grip. The Australian Museum advises caution because photo-based rodent identification is often difficult. [5]

Why might I see a young possum on an adult’s back?

Young ringtails leave the pouch and may ride on an adult’s back. The Australian Museum reports that males can carry young while females feed. [2]
