Possible
About 20% of wildlife watchers report an Oriental Whipsnake sighting in Doi Inthanon 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 30 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.
July and November
In those months about 30% of wildlife watchers report an Oriental Whipsnake in Doi Inthanon National Park on a given day, against under 5% in January, April–May and August–September, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Oriental Whipsnake 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.
9th of 10
Of the 10 parks where we can rate Oriental Whipsnake sightings, Doi Inthanon National Park ranks 9th at about 20%. The best odds are in Cuc Phuong National Park (Vietnam, about 50%), Bako National Park (Malaysia, about 40%) and Kaeng Krachan National Park (Thailand, about 40%). All parks ranked.
Same family: Colubridae

GBIF citizen-science records
It is estimated from how often the Oriental Whipsnake is recorded against all the reptiles logged in Doi Inthanon 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.
