With luck
About 10% of wildlife watchers report a Green Keelback sighting in Pune on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 10th most-seen of the 20 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July and September
In those months about 20% of wildlife watchers report a Green Keelback in Pune on a given day, against under 5% in March–May and December–January, the lowest months. Those are among Pune's wettest months, with about 400 mm of rain a month against almost none in January.
Only Pune, in our data
Pune is the only city on Wallace's Line with enough records to rate Green Keelback sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Colubridae
The closest relatives of the Green Keelback that you can see in Pune (family Colubridae, Colubrid Snakes) are Dhaman (about 30%), Trinket Snake (about 30%) and Indian Wolf Snake (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green Keelback is recorded against all the reptiles logged in Pune (14 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.
