Possible
About 20% of wildlife watchers report a Black Copper Rat Snake sighting in Jakarta on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 32nd most-seen of the 47 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
November
In that month about 30% of wildlife watchers report a Black Copper Rat Snake in Jakarta on a given day, against under 5% in May, September and December–January, the lowest months.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Black Copper Rat Snake sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 5 cities where we can rate Black Copper Rat Snake sightings, Jakarta ranks 3rd at about 20%, level with the leaders once rounded. The best odds are in Yogyakarta (Indonesia, about 20%) and Denpasar (Indonesia, about 20%).
GBIF citizen-science records
It is estimated from how often the Black Copper Rat Snake is recorded against all the reptiles logged in Jakarta (17 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.
