The Bhutan giant flying squirrel (Petaurista nobilis) is a species of rodent in the family Sciuridae. It is one of the largest among the flying squirrels.[2]


It has a narrow range restricted to central Nepal, Sikkim and western Arunachal Pradesh in India, and Bhutan.[3] It could occur in neighbouring forests in southern Tibet and northern Bangladesh, although it has not yet been reported from these areas.


The squirrel has bright chestnut-brown upper parts with orange tips to some of the hairs and pale rufous underparts. It is pale fulvous on the top of the head, shoulders, and in a narrow streak in the middle of the upper parts.[3]

It was previously considered as a sub-species of Hodgson's giant flying squirrel but later elevated to a full species based on its distinctness.[4][5] Two sub-species are recognised: P n. nobilis and P n. singhei.

Ecology and habitat[edit]

Its natural habitat is temperate broadleaf forests typically recorded between 1500 m to 3000 m elevation, but could also occur in contiguous coniferous forests.[3] Reports from Arunachal Pradesh 100 km east of its previous eastern limits to the range of this species indicate possible larger range in North-east India.[3] It appears to breed between March and April.[2]
