With luck
About 10% of wildlife watchers report a Butler's Ricefrog sighting in Guangzhou on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 13 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–May and July–October
In those months about 10% of wildlife watchers report a Butler's Ricefrog in Guangzhou on a given day, against under 5% in June and November–January, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Butler's Ricefrog sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 cities where we can rate Butler's Ricefrog sightings, Guangzhou has the highest daily chance: about 10%. Next come Singapore (Singapore, under 5%).
Same genus: Microhyla
The closest relatives of the Butler's Ricefrog that you can see in Guangzhou (genus Microhyla, Rice Frogs) are Ornate Chorus Frog (about 10%) and Beautiful Pygmy Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Butler's Ricefrog is recorded against all the amphibians logged in Guangzhou (23 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.
