Possible
About 20% of wildlife watchers report a Zhenhai Brown Frog sighting in Nanjing on a given day, based on 48 verified sightings from GBIF citizen-science data. It is the 3rd most-seen of the 11 amphibians 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.
February and November
In those months about 40% of wildlife watchers report a Zhenhai Brown Frog in Nanjing on a given day, against under 5% in January, April and June, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Zhenhai Brown Frog sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Yes
Of the 3 cities where we can rate Zhenhai Brown Frog sightings, Nanjing has the highest daily chance: about 20%. Next come Hangzhou (China, about 20%) and Ningbo (China, about 20%).
GBIF citizen-science records
It is estimated from how often the Zhenhai Brown Frog is recorded against all the amphibians logged in Nanjing (48 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.
