Eastern Nepal and Bangladesh to southeastern China, Indochina, and the Malay Peninsula
A wide variety of forests
Northern tree shrews have grayish, olive fur and are 5.5 to nine inches long (from nose to base of the tail), with a tail about as long as their body.
Mainly insects and fruit
Northern tree shrew parents build a nest for their young, in addition to their own nest. Females give birth to between two and four young. They nurse their young every two days and essentially ignore them between feedings—they do not groom them or care for their nest. The young will remain with the adults until sexual maturity.
Northern tree shrews typically live in monogamous pairs. One male and one female have overlapping territories; the male will defend his territory from other males, and the female will defend hers from other females.
