Northern Treeshrew
   
   

Order : SCANDENTIA
Family : Tupaiidae
Species : Tupaia belangeri

Head-Body Length : 16-23 cm
Tail Length : 15-20 cm

The Northern Treeshrew Tupaia belangeri occurs in many parts of mainland Southeast Asia and beyond, including most of Thailand, Myanmar, Cambodia, Laos and Vietnam. In southern Thailand, Peninsular Malaysia and Singapore it is replaced by the Common Treeshrew Tupaia glis.

This species occurs in a range of habitats including dense forest, karst forest, forest-edge and disturbed habitats including parks and gardens, from lowlands to montane areas. It is largely terrestrial in habits, but will climb on to low vegetation and fallen trees.

Its head and body dimensions are of typical treeshrew shape, and its tail is long and slender. Its hands are quite dextrous, more so than squirrels.

Its fur colour is brown to olive (with sometimes a reddish tinge in northern areas); individual hairs bear dark and pale bands, which give a grizzled appearance.

There is a narrow, pale stripe on each shoulder, which is a feature of most species of treeshrew. Female Tupaia belangeri have 3 pairs of mammae; this distinguishes the species from Tupaia glis, which has 2 pairs.

This is a highly adaptable, energetic, small mammal with a wide-ranging diet that includes insects, spiders, small lizards, buds and fallen fruits. It nests in a range of available spaces including tree holes, fallen trees and bamboo cavities.
