Likely
About 40% of wildlife watchers report a Banded Keelback sighting in Khao Sok National Park on a given day, based on 34 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 44 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
July and September
In those months about 60% of wildlife watchers report a Banded Keelback in Khao Sok National Park on a given day, against under 5% in February, the lowest month. Those are among Khao Sok National Park's wettest months, with about 250 mm of rain a month against 35 mm in February.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Banded Keelback sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 3 parks where we can rate Banded Keelback sightings, Khao Sok National Park has the highest daily chance: about 40%. Next come Doi Inthanon National Park (Thailand, about 20%) and Khao Yai National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Banded Keelback is recorded against all the reptiles logged in Khao Sok National Park (34 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.
