Indian giant squirrel


The Indian giant squirrel, or Malabar giant squirrel, is a large tree squirrel species in the genus Ratufa native to forests and woodlands in India. It is a diurnal, arboreal, and mainly herbivorous squirrel.

Distribution and habitat

This species is endemic to India, with main sections of its distribution in the Western Ghats, Eastern Ghats and Satpura Range as far north as Madhya Pradesh. It is found at altitudes of in tropical deciduous, semi-deciduous, and moist evergreen forests and woodlands. In general, its distribution is fragmented because it is intolerant of habitat degradation. The Indian Giant Squirrel generally nests in taller trees with a mean height of 11.08 in order to avoid predators.

Description

The Indian giant squirrel is one of the largest squirrels with a head–and–body length of, a tail that is about the same or somewhat longer, and a weight of, although rarely up to. Average for both sexes is about in head–and–body length, in tail length and in weight.
It has a conspicuous one-, two- or three-toned colour scheme. The colours involved can be whitish, creamy-beige, buff, tan, rust, reddish-maroon, brown, a dark seal brown or black. The underparts and the front legs are usually cream coloured, the head can be brown or beige, however there is a distinctive white spot between the ears. Otherwise the colours depend on the subspecies.

Subspecies

Ten subspecies have been described, but recent authorities generally recognise four:

Behaviour

The Indian giant squirrel is an upper-canopy dwelling species, which rarely leaves the trees, and requires "tall profusely branched trees for the construction of nests." It travels from tree to tree with jumps of up to. When in danger, the Ratufa indica often freezes or flattens itself against the tree trunk, instead of fleeing. Its main predators are the birds of prey like owlsand the leopard. The Giant Squirrel is mostly active in the early hours of the morning and in the evening, resting in the midday. They are typically solitary animals that only come together for breeding. The species is believed to play a substantial role in shaping the ecosystem of its habitat by engaging in seed dispersal. Diet includes fruit, flowers, nuts and tree bark. Some subspecies are omnivorous, also eating insects and bird eggs.

Family life

The Indian Giant Squirrel lives alone or in pairs. They build large globular nests of twigs and leaves, placing them on thinner branches where large predators can't get to them. These nests become conspicuous in deciduous forests during the dry season. An individual may build several nests in a small area of forest which are used as sleeping quarters, with one being used as a nursery.

Reproduction

Captive breeding of the Malayan giant squirrel, a close relative has indicated births in March, April, September and December. The young weigh 74.5 g at birth and have a length of 27.3 cm. In Canara, the Indian Giant Squirrel has been spotted with young in March.

Recognition

Indian Giant Squirrel is the state animal of the state of Maharashtra in western India.
