The Irrawaddy squirrel, known in the Himalaya as the hoary-bellied squirrel, varies in fur colour, with some greyish-brown and reddish-brown animals and some grizzled ones. Some have dark tips on the tail and pale hip patches. Head and body length is about 20cm and the tail is about the same (Wikipedia, general species account).
It mainly eats nuts, seeds, fruits, bark, lichen and various other vegetation, though it may occasionally take insects and small vertebrates. The Mammal Diversity Database lists Bhutan among its countries. The short source opened gives no habitat, breeding or Bhutan-specific detail, so none is stated.
