The northern brown bandicoot (Isoodon macrourus), a marsupial species, is a bandicoot found only on the northern and eastern coasts of Australia and nearby islands, mainly Papua New Guinea. It is not, however, found far inland.
This species can be set apart from other marsupials by two traits. It is both polyprotodont (i.e., several pairs of lower front teeth) and syndactylous. The northern brown bandicoot has typical body and tail lengths of 40 and 15 cm (15.7 and 5.9 in), respectively. On average it weighs 1,200 g (2.6 lb). This marsupial has a thick harsh coat but is not spiny. The dorsal pelage is light brown in appearance with speckled black patterns throughout. On the ventral surface it is solid white. The northern brown bandicoot has a reverse pouch so it won't fill with soil when digging. This bandicoot also has short, rounded ears and a short nose. One can easily mistake northern brown bandicoot for the southern brown bandicoot. The two species differ in both size, with the northern brown bandicoot larger, and regional locality, in that the southern brown bandicoot is found only on the southern coastline of Australia.
The male is typically 5–7 cm (2.0–2.8 in) longer and about 0.5 kilograms (1.1 lb) heavier than the female.
The populations of the northern brown bandicoot live in two different habitats: one during the dry season and the other during the wet season. During the dry season, this species lives in thick vegetation consisting of tall weeds, small trees, and dense shrubs. This probably occurs because of the sparse food supply that can be found. During the wet season though, the northern brown bandicoot "comes out" and roam open grasslands where a more abundant food source exists.
The northern brown bandicoot is one of relatively few native Australian ground-dwelling mammals that is able to survive within urbanized landscapes. The generalized dietary and habitat requirements, as well as a high reproductive output, undoubtedly facilitate the survival of the species in urban habitat fragments.
The northern brown bandicoot makes individual nests or homes on the ground consisting of simple mounds of hay and twigs that are well camouflaged and waterproof. The inside is hollow and large enough for just the single bandicoot. Some bandicoots use hollowed out tree trunks or abandoned rabbit dens for shelter. In general, however, the northern brown bandicoot shows a strong preference for homes in areas of low ground cover.
