†Bettongia gaimardi gaimardi
The eastern bettong (Bettongia gaimardi), also known as the southern bettong and Tasmanian bettong, is a bettong whose natural range includes southeastern Australia and eastern Tasmania.
Two formerly recognised species, Bettongia cuniculus (Tasmanian bettong) and Bettongia gaimardi (eastern bettong), were placed into a single species with two subspecies by Wakefield in 1967:
The introduction of the red fox and European rabbit to Australia led to the extinction of the mainland subspecies during the 1920s. The Tasmanian subspecies still exists. In 2012, a small population was reintroduced to the mainland in Canberra, where they appear to be doing well.
This animal's habitat is dry, open eucalypt forests and grassy woodlands at altitudes between sea level and 1,000 meters.
A major component of their diet is truffles and other underground fungi, as well as roots and tubers. Insects and grubs are also eaten. It is unique in that it will travel up to 1.5 km from its nest to a feeding area, a considerable distance for such a small creature.
A nocturnal animal, the bettong sleeps during the day in a domed nest. The nests are made with densely woven grass, leaves and shredded bark in a sheltered site such as a shallow depression in the ground or under a fallen log or clump of vegetation. The animal uses its curved prehensile tail to transport the nesting materials to the nest site. The animal only uses the nest for one or two nights, before it moves on in search of food.
Like other bettongs, the eastern bettong is a continuous breeder, producing young throughout the year. The gestation period is 21 days, after which the infant (referred to as a "joey") will remain in the pouch for an additional 105 days.
