Possible
About 30% of wildlife watchers report a Sarawak Keelback sighting in Kinabalu Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th 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.
December
In that month about 50% of wildlife watchers report a Sarawak Keelback in Kinabalu Park on a given day, against under 5% in March–April and September, the lowest months.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Sarawak Keelback sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Kinabalu Park, in our data
Kinabalu Park is the only park on Wallace's Line with enough records to rate Sarawak Keelback sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sarawak Keelback is recorded against all the reptiles logged in Kinabalu Park (27 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.
