Bhutan Giant Flying Squirrel

The Bhutan giant flying squirrel, also called Gray's or the noble giant flying squirrel, is one of the largest flying squirrels and lives in Himalayan forests. It has a narrow range restricted to central and eastern Nepal, Bhutan and the Indian states of Sikkim, far northern West Bengal, and western and central Arunachal Pradesh, and checklists also list Vietnam, Laos and China. It is mostly found at 1,500–3,000 m and has been recorded down to 800 m (Wikipedia, general species account).

It is mainly nocturnal but has also been seen at dawn and dusk, and it glides between trees on its patagium. It appears to breed in March and April, and although it lives in trees it has been seen feeding on the ground. Confusion with Hodgson's giant flying squirrel was resolved only in the late 1970s and early 1980s, when the two were shown to differ in colour pattern and size.
