With luck
About 10% of wildlife watchers report a Kutkai Keelback sighting in Doi Inthanon National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 30 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
May–June, August and December
In those months about 20% of wildlife watchers report a Kutkai Keelback in Doi Inthanon National Park on a given day, against under 5% in January–April, July and September–October, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Kutkai Keelback sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Doi Inthanon National Park, in our data
Doi Inthanon National Park is the only park on Wallace's Line with enough records to rate Kutkai Keelback sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Kutkai Keelback is recorded against all the reptiles logged in Doi Inthanon National Park (6 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.
