The black giant squirrel rarely enters plantations or settlements, preferring the wild forest. bicolor is diurnal and arboreal, but sometimes climbs down from the forest canopy to feed on the ground. It has been predicted through study that by the year 2050, this species may loose more than 97% of its present suitable habitat due to climate change in India. More than 20% of the presence records of the species has been observed above 1500 meters and up to 2700 meters in India. The species also may be found way beyond 1400 meters in several places. bicolor, along with land use, and vegetation. Several populations are present in the lower range of the Neora Valley National Park, Kalimpong, India.Ī recent study from India showed precipitation during the wettest month of a year is one of the major contributing factor for habitat preference of R. Īmong the better places to sight the black giant squirrel is the Kaziranga National Park in the state of Assam, India. bicolor is not as abundant as elsewhere in its range, which is probably due to competition from other arboreal species (especially primates) for food in the upper forest canopy. In the tropical rainforest of the Malay Peninsula and Indonesia, R. bicolor lives in tropical broadleaf evergreen and semi-evergreen forests, but is rarely seen in coniferous forests. bicolor dwells among tropical and subtropical coniferous and broadleaf forests. However, in some places this species is protected from hunting by law or tradition. bicolor's habitat has been steadily encroached upon by human settlement, timber harvesting and agriculture, which along with overhunting by human predation in parts of its range, has resulted in a total loss of up to 30% of the population in the past ten years. ![]() It ranges in elevation from sea level up to at least 1,400 metres (4,600 ft), in some of the most rugged land in the world. Ratufa bicolor's range includes a variety of bioregions that all share the commonality of being forested. On small islands off Myanmar and in the Strait of Malacca the black giant squirrel has reddish-yellowish underparts. In Sumatra, Java and Bali the hairs of the back and tail are light-tipped, making these sections appear relatively pale (however, the back is still distinctly darker than the underparts). The back, top of the head, ears and bushy tail are deep brown to black and the underparts are light buff-coloured. This species is typically distinctly bicoloured with dark upperparts and pale underparts. 30 cm (12 in) in head–and–body length and the tail 32 cm (13 in), but otherwise it resembles the typical subspecies. condorensis of Vietnam's Côn Sơn Island averages only c. The black giant squirrel is one of the largest species of squirrel in the world. An individual from Namdapha Tiger Reserve, Arunachal Pradesh, India
