Mountain treeshrew
species of mammal
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. Its tail is rather short and grizzled rufous above, but below more olivaceous yellow with a black tip. The lateral tail hairs are ringed. The head and body length measures 15–33 cm and the tail length measures 13–19 cm.
Distribution and habitat
Charles Hose collected the first specimen at about 4,000 ft (1,200 m) on Mount Dulit.
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.
The public source identifies “Mountain treeshrew” as species of mammal. This brief keeps that definition visible, then builds a research path around Mountain, treeshrew and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Mountain treeshrew”, the useful work is to connect “species of mammal” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Oct 13, 2025. The linked authority identifier is Q774635. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
