The black flying squirrel or large black flying squirrel (Aeromys tephromelas) is a species of rodent in the family Sciuridae. It is found in Brunei, Indonesia, and Malaysia; its habitat is primary and secondary forests and gardens where it uses tree hollows. It feeds on fruits, nuts and other vegetable matter. It is likely not threatened and is adaptable to habitat loss. Black flying squirrels tend to have smaller populations than other squirrels because female black flying squirrels breed infrequently and have a small litter size of just one young.

Possible
About 20% of wildlife watchers report a Black Flying Squirrel sighting in Sepilok on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 23 mammals we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July–August and November
In those months about 30% of wildlife watchers report a Black Flying Squirrel in Sepilok on a given day, against about 10% in April–June and September, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Black Flying Squirrel sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Sepilok, in our data
Sepilok is the only park on Wallace's Line with enough records to rate Black Flying Squirrel sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black Flying Squirrel is recorded against all the mammals logged in Sepilok (26 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.
