Animal Facts

Also known as the pale giant or cream coloured squirrel. It is a closed canopy species that is never seen on ground. It is one of the largest species found of squirrel in the world. The back and head of the body varies from dark brown to gray, and the belly varies from dark yellow to white. The ears are short and round. The adult squirrel’s head and body is from 322 to 350 millimetres (12.7 to 14 in) in length, and the tail is 373 to 438 millimetres (14.7 to 17.2 in) long, with an overall length of 695 to 788 millimetres (27.4 to 31.0 in); the weight is between 929 to 1,575 grams (2.05 to 3.47 lb).

This species is diurnal, active during morning and evening. They live either in pairs or alone. Unlike other tree squirrels, the cream-coloured giant squirrel does not sit upright with its tail arched over its back while feeding; instead, it balances itself with its hind feet on a branch so that its hands are free to control its food. In this position the axis of the squirrels body is held at right angles to the support, with its head and forequarters on one side of the branch, and the tail as a counterweight on the other side.

Although this squirrel often will make holes in trees for shelter, during the breeding season it constructs a large globular drey (or nest) in tree branches, roughly the size of an eagle’s aerie. The young are born and raised in this nest.

Where do they live?
