Possible
About 20% of wildlife watchers report a Bornean dark-necked slug snake sighting in Kinabalu Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 24th most-seen of the 69 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a Bornean dark-necked slug snake in Kinabalu Park on a given day, against under 5% in October and November, the lowest months. That is one of Kinabalu Park's wettest months, with about 550 mm of rain against 180 mm in February.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Bornean dark-necked slug snake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Kinabalu Park, in our data
Kinabalu Park is the only park on Wallace's Line with enough records to rate Bornean dark-necked slug snake sightings: about 20% of wildlife watchers there report one on a given day.
Same genus: Asthenodipsas
The closest relatives of the Bornean dark-necked slug snake that you can see in Kinabalu Park (genus Asthenodipsas) are Inger’s Slug Snake (about 30%), Smooth Slug Snake (about 20%) and Sabah Mountain Smooth Slug Snake (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bornean dark-necked slug snake is recorded against all the reptiles logged in Kinabalu Park (21 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.
