The northern treeshrew (Tupaia belangeri) is a treeshrew species native to Southeast Asia. In 1841, the German zoologist Johann Andreas Wagner first used the specific name Cladobates belangeri for treeshrews that had been collected in Pegu during a French expedition to Southeast Asia. These specimens were described by Isidore Geoffroy Saint-Hilaire in 1834 in whose opinion they did not differ sufficiently from Tupaia tana to assign a specific rank.
Results of a telemetry study involving northern treeshrews showed that their body temperature varies from 35 °C (95 °F) during the night to 40 °C (104 °F) during the day. This difference is larger than in other endotherms, and indicates that the circadian rhythms of body temperature and locomotor activity are synchronized.
Adults weigh 0.2 kg (0.44 lb). The maximum longevity of the northern treeshrew is 11 years. Besides humans, the northern treeshrew is the only mammal known to willingly consume spicy food. This is due to a genetic mutation rendering it much less sensitive to the effects of capsaicin.

Likely
About 40% of wildlife watchers report a Northern Treeshrew sighting in Cat Tien National Park on a given day, based on 62 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 28 mammals we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
March
In that month about 70% of wildlife watchers report a Northern Treeshrew in Cat Tien National Park on a given day, against under 5% in September and October, the lowest months. That is one of Cat Tien National Park's driest months, with about 30 mm of rain against 490 mm in July.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Northern Treeshrew sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 4 parks where we can rate Northern Treeshrew sightings, Cat Tien National Park has the highest daily chance: about 40%. Next come Kaeng Krachan National Park (Thailand, about 40%) and Cuc Phuong National Park (Vietnam, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Northern Treeshrew is recorded against all the mammals logged in Cat Tien National Park (62 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
