The least pygmy squirrel (Exilisciurus exilis), also known as the plain pygmy squirrel, is a species of rodent in the family Sciuridae. This plain olive-brown squirrel is endemic to forests, mostly below an altitude of 750 m (2,500 ft) but locally significantly higher, on the Southeast Asian islands of Borneo, Sumatra and Banggi. Together with the African pygmy squirrel, the least pygmy squirrel is the smallest squirrel in the world, having a total length of 10–14 cm (3.9–5.5 in) and a weight of 12–26 g (0.42–0.92 oz).

Possible
About 30% of wildlife watchers report a Least Pygmy Squirrel sighting in Kinabalu Park on a given day, based on 39 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 18 mammals we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
February, June–July and September–October
In those months about 40% of wildlife watchers report a Least Pygmy Squirrel in Kinabalu Park on a given day, against under 5% in April and November, the lowest months.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Least Pygmy Squirrel sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
2nd of 4
Of the 4 parks where we can rate Least Pygmy Squirrel sightings, Kinabalu Park ranks 2nd at about 30%. The best odds are in Danum Valley Conservation Area (Malaysia, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Least Pygmy Squirrel is recorded against all the mammals logged in Kinabalu Park (39 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.
