Allied rock-wallaby
The allied rock-wallaby or Weasel rock-wallaby is a species of rock-wallaby found in northeastern Queensland, Australia. It forms part of the P. lateralis/penicillata species complex and is very similar to six other species of rock-wallaby found in this area; these include the Cape York rock-wallaby, the unadorned rock-wallaby, the Herbert's rock-wallaby, the Godman's rock-wallaby, the Mareeba rock-wallaby and the Mount Claro rock-wallaby.
Description
Few features distinguish the allied rock-wallaby from its close relatives but each species lives in a different part of Queensland and northern New South Wales; where their ranges overlap slightly, there is some hybridisation. They all have upper parts that range from brown to grey, and paler underparts. They usually have a dark muzzle and a dark patch around the armpits. On the face is a pale cheek stripe, and across the hips is another pale stripe.Distribution and habitat
The allied rock-wallaby is endemic to Queensland in Australia. Its range extends from Townsville to the Burdekin River, the Bowen River, Croydon and Hughenden, and includes Magnetic and Palm Islands. It occurs at elevations of up to in rocky areas, both in woodland and in more lightly-treed areas, even when agricultural land is nearby. Typical habitat is mountainous areas with cliffs, ledges, caves and rock piles.Behaviour
The diet comprises grasses and shoots of herbaceous plants, with up to thirty percent of the diet being browsed from bushes. They have a small home range during the wet season when food is readily available, but range much more widely during the dry season. While foraging, out-of-pouch young are often left hidden in rock crevices.The allied rock-wallaby is behaviourally monogamous, but not all the offspring are sired by the supposed father. The gestation period is about thirty days, the joey leaves the pouch at six to seven months and is fully weaned when nearly a year old. Young adults may disperse over distances of two kilometres or so, and longevity is about seven years.
