Rare
Under 5% of wildlife watchers report a Rainbow Mud Snake sighting in Bangkok on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 34th most-seen of the 35 reptiles we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February and June–July
In those months about 10% of wildlife watchers report a Rainbow Mud Snake in Bangkok on a given day, against under 5% in March–May and August–January, the lowest months.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most Rainbow Mud Snake sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 2
Of the 2 cities where we can rate Rainbow Mud Snake sightings, Bangkok ranks 2nd at under 5%. The best odds are in Jakarta (Indonesia, about 20%).
Same family: Homalopsidae
The closest relatives of the Rainbow Mud Snake that you can see in Bangkok (family Homalopsidae, Mud Snakes) are Jack's Water Snake (about 10%) and Southeast Asian Bockadam (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rainbow Mud Snake is recorded against all the reptiles logged in Bangkok (7 verified sightings), 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.
