Pseudomys desertor occurrence records |
The desert mouse (Pseudomys desertor), also known as the brown desert mouse, [1] is a species of rodent in the family Muridae. It is endemic to Australia. [1] The first desert mouse specimen was collected by Australian zoologist Gerard Krefft on the Blandowski Expedition in 1856-57, between Gol Gol Creek and the Darling River. [2]
The desert mouse has bright chestnut brown fur above, interspersed with long dark guard hairs which give it a spiny appearance. [3] Its belly fur is a light grey-brown. [3] The tail looks scaly and slightly bi-coloured, with length equal to or shorter than the animal's head-body length. [3] A defining feature of the desert mouse is its pale orange eye-ring, which may be used to distinguish it from the Western chestnut mouse Pseudomys nanus where their habitat overlaps in the northern Tanami Desert. [3]
Typical measurements for the desert mouse are 70–105 mm for head-body length, and 67–103 mm for tail length. [3] Weight is between 15-35 g. [3]
Widespread throughout the arid zone of Australia, the desert mouse also inhabits in the north dry savannah region of Queensland. [4] Its preferred habitat ranges from sand dunes with spinifex to rocky hillsides, which it uses to create shallow burrows. [4]
Fossilized remains of the desert mouse have been found from Cape Range National Park and the Nullarbor Plain in Western Australia, to the northern Flinders Ranges of South Australia, and Lake Victoria in New South Wales. [5] When combined with modern records, these fossil records suggest that the species once had an even more extensive range across arid Australia. [5]
Predominantly a folivore, [6] the desert mouse has also been known to eat seeds and invertebrates when leaves and shoots are less widely available. [7] Laboratory studies of the desert mouse have found its water requirements to be quite low. [5]
The reproduction rate of the desert mouse is very high, even when compared with other species in the Pseudomys genus. [6] This allows populations to increase rapidly after periods of suitable rainfall. [3] Females are sexually receptive and fertile in a 7-9 day cycle. [3] The gestation period lasts 27–28 days, with an average litter size of three pups who will themselves become reproductively mature at about ten weeks. [3]
The desert mouse appears to be less common in areas affected by fire or grazing. [1] Other threats are posed by introduced species, such as predation by foxes and feral cats, [7] competition from other herbivores like the house mouse (Mus musculus), [7] and habitat alteration by exotic grasses in Queensland.

The dusky hopping mouse, is a small rodent endemic to Australia, inhabiting desert regions characterised by sand dunes. Populations have experienced significant declines since the arrival of Europeans, and continue to be subject to threatening processes. It is currently listed as a threatened species.
The bush rat or Australian bush rat is a small Australian nocturnal animal. It is an omnivore and one of the most common indigenous species of rat on the continent, found in many heathland areas of Victoria and New South Wales.
Gould's mouse, also known as the Shark Bay mouse and djoongari in the Pintupi and Luritja languages, is a species of rodent in the murid family. Once ranging throughout Australia from Western Australia to New South Wales, its range has since been reduced to five islands off the coast of Western Australia.
Pseudomys is a genus of rodent that contains a wide variety of mice native to Australia and New Guinea. They are among the few terrestrial placental mammals that colonised Australia without human intervention.
The long-tailed mouse is a native Australian mammal in the Order Rodentia and the Family Muridae. It is found only on the island of Tasmania. The long-tailed mouse is an omnivore that feeds on insects and a range of plants. It is found in forested areas, particularly in sub-alpine scree, and may live in burrows.
The kultarr is a small insectivorous nocturnal marsupial inhabiting the arid interior of Australia. Preferred habitat includes stony deserts, shrubland, woodland, grassland and open plains. The kultarr has a range of adaptations to help cope with Australia's harsh arid environment including torpor similar to hibernation that helps conserve energy. The species has declined across its former range since European settlement due to changes in land management practices and introduced predators.
The heath mouse is a species of mouse in the subfamily Murinae, the Old World rats and mice, found in Australia.
The plains rat(Pseudomys australis), also known as the palyoora, plains mouse and eastern mouse, is a conilurine rodent native to arid and semi-arid Australia. Referred to as the pallyoora or yarlie by Indigenous groups, the plains rat was once widely distributed across central Australia, including north-west New South Wales and south-west Queensland; however, habitat degradation due to grazing, introduced predators and drought have contributed to its decline. Consequently, the plains rat has been listed as 'presumed extinct' in New South Wales and Victoria, 'endangered' in the Northern Territory and Queensland and 'vulnerable' in Western Australia and South Australia. While recent research has indicated the presence of the plains rat in areas such as the Fowlers Gap and Strzelecki Desert regions of New South Wales and within the Diamantina National Park in Queensland, there are only five sub-populations currently recognised nationally, none of which coincide with recent discoveries of the plains rat. As the current population trend of the plains rat has been listed as 'declining' by the International Union for the Conservation of Nature (IUCN), the IUCN conservation status for the species is 'vulnerable'.
The Forrest's mouse, or desert short-tailed mouse, is a small species of rodent in the family Muridae. It is a widespread but sparsely distributed species found across arid and semi-arid inland Australia, commonly found in tussock grassland, chenopod shrubland, and mulga or savannah woodlands.
The ash-grey mouse is a rodent in the family Muridae. Larger and more robust than Mus musculus, the common house mouse, it is found only in Southwest Australia.
Bolam's mouse is a species of nocturnal, burrowing rodent in the family Muridae that inhabits the semi arid and southern arid regions of Australia. It has a number of physiological and behavioural adaptations developed to cope with an extremely varied climate. Including the ability survive by extracting water from seeds alone, the production of highly concentrated urine, low water content faeces and nocturnal activity.
Western pebble-mound mouse or Ngadji is a burrowing and mound building rodent in the family Muridae. They occur in the Pilbara, a remote region in the northwest of Australia.
The sandy inland mouse is a species of rodent in the family Muridae. Also known as the Hermannsburg (Mission) false-mouse or Hermannsburg mouse, it is endemic to Australia and found widely yet sparsely through arid and semi-arid areas.
The New Holland mouse also known as a Pookila is a species of rodent in the family Muridae. It was first described by George Waterhouse in 1843. It vanished from view for over a century before its rediscovery in Ku-ring-gai Chase National Park north of Sydney in 1967. It is found only in south east Australia, within the states of New South Wales, Queensland, Victoria, and Tasmania.
The western mouse or walyadji is a species of rodent in the family Muridae. Once widespread across a larger range, it has become restricted to around ten reserves of remnant bushland in Southwest Australia and declared near threatened by extinction. They are small and robust mice that live in burrows in sandy soil, venturing out at night to forage in nearby area.
Pseudomys pilligaensis, commonly known as the Pilliga mouse or poolkoo, is a species of rodent in the family Muridae. Its distribution comprises the Pilliga forest region of New South Wales, Australia, specimens have also been trapped in the Warrumbungle National Park and Weetalibah Nature Reserve. Its conservation status is currently listed as "Data Deficient" due to unresolved questions on its taxonomic status.
The central rock rat, also known as the central thick-tailed rock-rat, Macdonnell Range rock-rat, and Australian native mouse, is a Critically Endangered species of rodent in the family Muridae endemic to Australia.
The chestnut-rumped thornbill is a small passerine bird in the family Acanthizidae, endemic to Australia.

The crest-tailed mulgara is among a group of native predatory mammals or mesopredators endemic to arid Australia.
The brush-tailed mulgara, previously the mulgara Dasycercus cristicauda is a medium sized carnivorous Australian marsupial species weighing approximately 100 g (3.5 oz). The brush-tailed mulgara is sexually dimorphic with males being much larger than females. Their body length is 12 to 17 cm, and tail length is 6–10 cm (2.4–3.9 in). They store fat in their tail which at times can be over 16 mm (0.63 in) wide at the base.
