Possible
About 30% of wildlife watchers report a Rough Mabuya sighting in Tanjung Puting National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 8 reptiles 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.
August
In that month about 60% of wildlife watchers report a Rough Mabuya in Tanjung Puting National Park on a given day, against under 5% in June, the lowest month. That is one of Tanjung Puting National Park's driest months, with about 150 mm of rain against 350 mm in November.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Rough Mabuya 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 6
Of the 6 parks where we can rate Rough Mabuya sightings, Tanjung Puting National Park ranks 2nd at about 30%. The best odds are in Sepilok (Malaysia, about 40%).
GBIF citizen-science records
It is estimated from how often the Rough Mabuya is recorded against all the reptiles logged in Tanjung Puting National Park (8 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.
