Rare
Under 5% of wildlife watchers report a Butler's Ricefrog sighting in Singapore on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 20 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Butler's Ricefrog in Singapore on a given day, so our monthly data shows no clear season.
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.
2nd of 2
Of the 2 cities where we can rate Butler's Ricefrog sightings, Singapore ranks 2nd at under 5%. The best odds are in Guangzhou (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Butler's Ricefrog is recorded against all the amphibians logged in Singapore (10 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.
