With luck
About 10% of wildlife watchers report a Thomas's Flying Squirrel sighting in Sepilok on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 23 mammals we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
January and October
In those months about 20% of wildlife watchers report a Thomas's Flying Squirrel in Sepilok on a given day, against under 5% in February–March, May–August and November–December, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Thomas's Flying Squirrel sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Thomas's Flying Squirrel sightings, Sepilok ranks 2nd at about 10%. The best odds are in Danum Valley Conservation Area (Malaysia, about 20%).
GBIF citizen-science records
It is estimated from how often the Thomas's Flying Squirrel is recorded against all the mammals logged in Sepilok (6 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.
