This species is very secretive, nocturnal and fossorial. No information is available on its diet but usually it comprises of insects and their larvae, earthworm and other invertebrates (Kamruzzaman 2009, Khan 1982, 1985, 1987, 2015). It is purely a forest floor dwelling mammal.

It inhabits primary and mature secondary mixed evergreen and deciduous Sal forests. It is tolerant to some degree of habitat modifications (Kamruzzaman 2009, Han 2008). It spends time both in trees and on the ground, moves very fast and feeds on arthropods, fruits and leaves.

The species is found at community households and crop fields.

Typical habitats are forest and forest edges, densely vegetated bamboo bushes, and sun-grass fields and found even with the harvested remains in agricultural fields (Molur et al. 2005). They are mostly arboreal and usually inhabits forest and forest edge.

It occurs in a wide variety of habitats with sufficient trees such as primary and secondary forests, scrub forests, and gardens, including the degraded areas and areas around human habitation (Smith and Xie 2008). It is diurnal and arboreal. This squirrel feeds on fruits, vegetables and some insects. It takes shelter in tree holes. No information is available on its breeding (Francis 2008).

It inhabits only the mixed evergreen forested areas. It is diurnal and arboreal.

House Rats adapt to a wide range of habitats. In urban areas they are found around storehouses, residential buildings, and other human settlements. They are also found in agricultural areas, such as in crop fields. In urban areas, they are commonly found in wall cavities and false ceilings as well as they prefer to live in dry upper levels of buildings or roofs. In the wild, they live in cliffs, rocks, the ground, and trees. This species is primarily commensal with the human beings but also found in a diverse natural and semi-natural habitat. It is a serious pest to the crops of all kinds, stored grains, food items and responsible for carrying and spreading diseases like the plague. It walks, runs, swims and climbs trees at ease. It builds a nest of dry materials that could be parts of linen, books and other household materials in a disused corner of a house, store house and in burrows. It is a prolific breeder.

It lives in all types of habitats except water bodies without any vegetation or floating material. It is at home in the cities as well as in the villages or the crop fields.The Brown Rat, also called Tree Rat is the most arboreal among the rats found in the countryside and forests. It usually lives in pairs or in a family group in a burrow or tree-nest and group being dominated a male that often defends its virtually borderless territory against an intruding male. It is a true omnivore (Sarker et al. 2013). This species has an acute sense of hearing and sensitive to ultrasound. It is a good swimmer, both on the surface and underwater. During excessive flood it climbs to trees and leads its normal life there up to the time the water recedes (Khan 1985, 1987, Nowak and Paradiso 1983, Parker 1990). This spcies also produces communicative noises audidle to humans.

The species has been found at community households and bamboo forests.
