Possible
About 30% of wildlife watchers report a Devaka’s Fan-throated Lizard sighting in Wilpattu National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 14 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.
September
In that month about 60% of wildlife watchers report a Devaka’s Fan-throated Lizard in Wilpattu National Park on a given day, against under 5% in June and November–January, the lowest months.

GBIF citizen-science records
It is estimated from how often the Devaka’s Fan-throated Lizard is recorded against all the reptiles logged in Wilpattu National Park (10 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.
