In the Bangladesh context, its habitat is restricted to the cities, towns and villages in the Revenue Divisions of Rangpur, Rajshahi and Khulna. Diurnal and semi-arboreal. It lives in the villages and towns of the districts under the Divisions of Rangpur, Rajshahi and Khulna. It prefers gardens over paddy and other crop fields. Feeds almost entirely on fruits, vegetables, leaves, boiled rice and bread offered by people, and some small animals. It is a very active animal and builds a huge nest called drey in canopies of tall trees. It can cause damage to cultivated fruits like guava, sapota, mango, etc.

It inhabits forested hill and foothills ranging up to 800m above mean sea level. It occurs in mixed evergreen forests in Bangladesh. This squirrel is terrestrial. It is a diurnal and arboreal species though it also forages on the forest floor. It feeds on fruits, vegetables, nuts and latex from tree bark as well as nectar.

The species lives in bamboo thickets, forests, grassy areas, and gardens in hilly or mountainous regions, at elevations up to 4,000 meters. They can burrow different types of soil, from loose well drained to hard and stony soil (Carleton and Musser 1984, Nevo 1999, Nowak 1999). It feeds on young grass, leaves and bamboo roots and shoots. Usually spends daytime in its holes and burrows, coming out at evening and forage widely through bamboo bushes (UNDP Bangladesh 2008).

It lives in forests, in well-wooded villages and semi-urban habitats with plantations bordering forests. A few pairs live in Dhaka city too. It is diurnal and arboreal but also occasionally comes to the ground. It occurs as solitary animal or in pairs. This squirrel feeds on leaves, fruits, vegetables, nuts, barks, latex, flowers and nectar. It loves to drink date juice extracted during winter. It builds its huge drey in tree tops with dry grass, leaves and twigs having an entry on one side (Khan1982, 2015, Khan 2008, Kamruzzaman 2009).

This species is diurnal. It is arboreal but also spends time on the ground. Feeds on leaves, fruits, seeds, nuts, insects (Francis 2008, Kamruzzaman 2009). Unlike other squirrels, it crosses long distance or run away through ground when disturbed. It is found in mixed evergreen forests but also seen in plantations and disturbed habitats nearby.

The species has been found at upland community households.

It is one of the most adaptable mammals of Bangladesh and a commensal to human beings. This species is terrestrial, burrower, nocturnal and crepuscular It is an apt swimmer, climber and digger. Usually consumes vegetables, grass, roots, grains, tubers, seeds, leaves, fruits of all kinds and also invertebrates There is no fixed breeding season for it but most of it takes place when grains are ready for harvesting (Francis 2008, Khan 1982, 1985, 1986, 2015, Khan 2008).

This species is terrestrial, burrower and crepuscular. Usually aggressive; erects piles of long hairs and grunts when excited. Feeds on variety of foods but usually vegetables, grass, roots, grains, tubers, seeds and also invertebrates (Chakma 2009). It inhabits a wide range of habitats including forests, agricultural lands and suburban areas. Prefers cultivated land (Chakma 2009). It is a known pest of all cultivated crops and stored grains (Khan 1987).

It occurs mainly in subtropical and tropical montane forests. It is most active at night when it forages alone and roosts during the day in groups. Feeds on vegetable matter of the forest, but rarely feeds on crops, insects and carrion (Grazimek et al. 2003). It is able to run, climb and swim. Digs tunnels for daytime shelter that can be about 3.5 m long (Storch and Parker 1990). Lays one or two offspring per litter and usually two litters per year. Gestation period is 100 to 110 days (Smith and Xie 2008). Both parents raise the young and actively guard them from enemies.

Asian Elephants are generalists and they occur in grassland, tropical evergreen forest, mixed evergreen forest, moist deciduous forest, dry deciduous forested and dry thorn forest in addition to cultivated and secondary forests and scrublands. Asian Elephants are social animals and live in herds. They feed on grass and other vegetations but also raid crops. Senses of smell and hearing are well developed (Islam et al. 1999, IUCN Bangladesh 2000, Khan 1980, 1985, 1987).
