Possible
About 20% of wildlife watchers report a Triangle Keelback sighting in Jakarta on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 27th most-seen of the 47 reptiles we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
October and November
In those months about 30% of wildlife watchers report a Triangle Keelback in Jakarta on a given day, against under 5% in April–May and August, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Triangle Keelback sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 cities where we can rate Triangle Keelback sightings, Jakarta has the highest daily chance: about 20%. Next come Bandung (Indonesia, about 10%) and Kuala Lumpur (Malaysia, about 10%).
Same family: Colubridae
The closest relatives of the Triangle Keelback that you can see in Jakarta (family Colubridae, Colubrid Snakes) are Oriental Whipsnake (about 60%), Common Bronze-back (about 40%) and Common Wolf Snake (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Triangle Keelback is recorded against all the reptiles logged in Jakarta (25 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.
