With luck
About 10% of wildlife watchers report an Ueno's Brown Frog sighting in Seoul on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 9 amphibians 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.
February and March
In those months about 20% of wildlife watchers report an Ueno's Brown Frog in Seoul on a given day, against under 5% in April, July and October–January, the lowest months. Those are among Seoul's driest months, with about 35 mm of rain a month against 360 mm in July.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Ueno's Brown Frog sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Seoul, in our data
Seoul is the only city on Wallace's Line with enough records to rate Ueno's Brown Frog sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ueno's Brown Frog is recorded against all the amphibians logged in Seoul (31 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.
