The mountain treeshrew (Tupaia montana) is a treeshrew species within the Tupaiidae. It is endemic to Borneo and inhabits montane forests in Sarawak and Sabah, Malaysia, and Kalimantan, Indonesia, as well as a part of southeastern Brunei. The first specimen was described by Oldfield Thomas and was part of a zoological collection from northern Borneo obtained by the British Museum of Natural History. == Characteristics == The mountain treeshrew is dark grizzled rufous above with an indistinct black line along the back.

Mountain treeshrews have mostly been recorded in montane outcrops above 600 m (2,000 ft). == Ecology and behaviour == In their natural habitat, mountain treeshrews were observed being active during the day. They forage on the ground among fallen logs and branches where they feed mostly on arthropods. They also consume large quantities of wild fruits and berries, eating…
