Possible
About 20% of wildlife watchers report a Sri Lankan Flapshell Turtle sighting in Udawalawe National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 9 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
February and October
In those months about 30% of wildlife watchers report a Sri Lankan Flapshell Turtle in Udawalawe National Park on a given day, against under 5% in April, June–August and November, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Sri Lankan Flapshell Turtle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Sri Lankan Flapshell Turtle sightings, Udawalawe National Park ranks 3rd at about 20%. The best odds are in Wilpattu National Park (Sri Lanka, about 60%) and Yala National Park (Sri Lanka, about 30%).
GBIF citizen-science records
It is estimated from how often the Sri Lankan Flapshell Turtle is recorded against all the reptiles logged in Udawalawe National Park (12 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.
