Black Giant Squirrel

Ratufa bicolor

Near Threatened

Spotted something wrong?

The black giant squirrel is one of the largest squirrels in the world: including the tail it can exceed a metre in length. It has a glossy black back and an intensely orange-yellow belly. It lives in the canopy of the forests of the eastern Himalaya, Indochina, the Malay Peninsula and Indonesia, and virtually never comes down to the ground. It feeds on fruit, seeds, bark, eggs and insects. It builds large spherical nests of twigs and leaves in the high forks of trees.
