It occurs mainly in mixed evergreen forests in the hills and mountains. It is most active at dawn and dusk and rests during most of the day in thick vegetation. Usually occurs as solitary but rarely in small groups. Serow feeds on grass, shoots and leaves. It defends the feeding range from intruder serows. It is able to move in steep rocky slopes. Mating takes place during October-November. A single young is born usually during September-October after a gestation period of 7-8 months (Duckworth et al. 2008).

Gaur occurs mainly in evergreen, mixed evergreen and moist deciduous forests, but also occurs in dry deciduous forests and forest peripheries. It is nocturnal but also diurnal in undisturbed areas. It lives in groups of few to nearly 50 Gaurs. Gaur is basically a grazer but would browse on bamboo leaves, reeds and shrubs. It depends on water for drinking, but does not normally bathe or wallow. Males make mating call during the mating season (Asmat 2009, Duckworth et al. 2008).

Presently, it inhabits denuded mixed evergreen forest, especially grass-reed field dominated savanna country that has taken over areas which became barren due to removal of indigenous forests in the Chittagong Hill Tracts of Bangladesh. Where undisturbed, Hog Deer tends to be crepuscular, with significant daytime activity and some at night, especially in the hot and wet seasons (Dhungel and O'Gara 1991). In some areas it seems to have become more nocturnal and solitary, presumably through hunting pressure. The main social group is a female and fawn (Timmins et al. 2012).

Spotted Deer thrives in a variety of habitats, but usually avoid extremes for example dense moist forests and open semi-desert or desert. Moist and dry deciduous forest areas, especially adjoining dry thorn scrub or grasslands appear to be the best areas, and highest densities of Chital are reported from these habitats. Short grasslands habitat, swampy meadows and glades adjoining forest areas, coastal dry evergreen forests, mixed forests or plantations with Teak (Tectona grandis) and Sal (Shorea robusta) are also used as habitat. (Raman in press). The Spotted Deer is a gregarious and frequently found in herds of a few individuals to 100 or more. It feeds largely on grasses at all sessons with green grasses less than 10 cm high seems to be preferred. It also feeds on flowers and fruits. Chital uses more wooded habitat during the cool-dry season and early summer (November to May), where fallen fruit, leaf litter, and browse are available. In open grassland and tropical dry thorn forest, Chital density increases with the onset of monsoon rains and flush of plant growth (Mishra 1982, Moe and Wegge 1994, Khan 1996, Raman et al. 1996).
