Indomalayan Pencil-tailed Tree Mouse

The Indomalayan pencil-tailed tree mouse is an arboreal rodent in the family Muridae. It is found in north-eastern India, southern China (including Hainan), Myanmar, Thailand, Laos, Cambodia, Vietnam, Peninsular Malaysia and Indonesia (Java, Sumatra, the Mentawai Islands and some other islands) (Wikipedia, general species account).

Like all members of its genus it builds its nest between stalks of bamboo, constructing a bundle of leaves and branches between two stalks and gnawing through part of them to enter the nest. The mice are sociable and may share their nests (Wikipedia, general species account).
