Possible
About 20% of wildlife watchers report a Zhenhai Brown Frog sighting in Ningbo on a given day, based on 13 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a Zhenhai Brown Frog in Ningbo on a given day, against under 5% in February, April–May, July and September–December, the lowest months. That is one of Ningbo's wettest months, with about 220 mm of rain against 70 mm in December.
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.
Among the best
Of the 3 cities where we can rate Zhenhai Brown Frog sightings, Ningbo ranks 3rd at about 20%, level with the leaders once rounded. The best odds are in Nanjing (China, about 20%) and Hangzhou (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 Ningbo (13 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.
