With luck
About 10% of wildlife watchers report a Chinese Kukri Snake sighting in Nanjing on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 11th most-seen of the 11 reptiles we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Chinese Kukri Snake in Nanjing on a given day, against under 5% in September to May, the lowest months. That is one of Nanjing's wettest months, with about 240 mm of rain against 40 mm in December.

Across all the parks we cover, that three-hour window holds the most Chinese Kukri 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.

GBIF citizen-science records
It is estimated from how often the Chinese Kukri Snake is recorded against all the reptiles logged in Nanjing (5 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.
