Golden Jackals are opportunistic and venture into human habitation at night to feed on garbage. They usually occur in groups but could be found as solitary or in pairs. They are highly adaptable and opportunistic foragers with varied diet, which consists of rodents, ground birds and their eggs, reptiles, frogs, fish, insects and fruits. They are crepuscular to nocturnal. They can live in a wide variety of habitats. Jackals occupy short to medium grasslands, forests, and agricultural lands, rural and suburban habitats. They usually hide inside woodlots, graveyards and Hindu cremation grounds (Khan 2008, 2015).

Mixed evergreen forest is the Hog Badger's principal habitat. It spends the day time in burrows that it digs for itself or in convenient natural shelters. It has been also reported from the homestead vegetation bordering forests. The Hog Badger is nocturnal, vegetarian and scavenger. Its feeding behaviour is to some extent similar to Wild Boar as it keeps digging in the wet and soft forest floor to fetch the worms and small creature as well as plant matters with its pronounced snout (Khan 2015). It forages using its powerful sense of smell. Worms and other invertebrates are taken along with roots and tubers which are pulled up with the snout and long claws of the fore paws. Fruits are also eaten and it is likely that they may also take any small mammals which it comes across (Asmat 2009). Little is known about its breeding habits, though litter size seems to be two or three young, and in captivity the average lifespan is 14 years.

This species is strongly arboreal and secretive. Primarily frugivorous, but also feeds on a wide range of animal food. Probably breeds throughout the year and there may be two litters per year, with two to three young in each litter (Duckworth et al. 2008). It occurs in evergreen and semievergreen forests including degraded areas having some contiguity of canopy.

This species occurs in the mixed evergreen forest and bamboo clumps in the northeast and southeast regions of Bangladesh. Binturongs are nocturnal and mostly solitary and tend to evade each other, but are not strictly territorial. They spend the majority of their time in tree but also have a high level of ground activity as they are too large to jump from tree to tree (Widmann et al. 2008). Binturongs have also been documented swimming and diving in order to obtain food (Cosson et al. 2007). Their prehensile tail acts as another limb as they climb slowly and carefully. Their hind legs can rotate backwards to enhance their back claws' ability to grasp as they climb trunks.

It inhabits natural habitats of ponds and lakes, rivers and streams, coastal tide pools and estuaries, freshwater and mangrove swamps and also near human habitats, especially in rice fields (Khan 2008). This species lives in extended family groups of about 12 individuals with only the alpha pair breeding; offsprings from previous years help to raise the young. It is an excellent swimmer and performs swimming by moving hind legs and tail. It can dive under water for about eight minutes. In the riverine systems, it choose areas with low vegetation and its nesting burrows are dug into the muddy banks. This species spends most of its time on land unlike most other otters. It feeds mainly on invertebrates such as crustaceans and mollusks, but is also known to feed on vertebrates, in particular amphibians (Hussain 2008, Khan 2008).

This species is most active in the early morning and late afternoon, though they become nocturnal in disturbed areas, where activity usually commences shortly before sunset and continues throughout the night. They occur solitary, in pair and also sometimes in groups. Wild Boars are omnivorous. They predominantly eat plant matter, particularly crops, fruits, grains, tubers, roots, and green plants. They have also been known to consume carrion, small rodents, insects, and worms. They adjust their diets based on availability of food, which can vary with seasons, weather conditions, and locations (Oliver and Leus 2008). Wild Boar is ecologically flexible and lives in habitats ranging from closed natural and planted forests to open scrublands with some cover, such as grasslands, wooded forests, agricultural areas, shrublands and marshy swamplands. They require a nearby water source and shelter (dense vegetation) to protect and conceal them from predation (Kamruzzaman 2009).

Sambar lives in dense undergrowth and tall grassbeds in the mixed evergreen forests as well as denuded forests locally called unclassed state forests in the Greater Chittagong Hill Tracts (Khan 1985). Sambar lives singly, in pair of in small family groups. It is mostly active at night but could forage at daytime where large carnivores like the tiger and leopard are absent. It is basically a grazer and to some extent a browser and always need to drink water (Khan 1985).

Barking Deer is associated with forest and adjacent areas and also occurs in degraded forests and nearby tea gardens. It is terrestrial and crepuscular. The diet is mostly fruits, buds, tender leaves, flowers, herbs and young grass (Kitchener et al. 1990).
