Rare
Under 5% of wildlife watchers report a Proto wrinkled frog sighting in Tokyo on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 11 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.
July
In that month about 10% of wildlife watchers report a Proto wrinkled frog in Tokyo on a given day, against under 5% in August to June, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Proto wrinkled frog sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Tokyo, in our data
Tokyo is the only city on Wallace's Line with enough records to rate Proto wrinkled frog sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Ranidae
The closest relatives of the Proto wrinkled frog that you can see in Tokyo (family Ranidae, Typical Frogs) are American Bullfrog (about 10%), Daruma Pond Frog (about 10%) and Japanese Brown Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Proto wrinkled frog is recorded against all the amphibians logged in Tokyo (11 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.
