Possible
About 20% of wildlife watchers report a Diadem Rain Frog sighting in Yasuní National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 22nd most-seen of the 49 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September and December
In those months about 30% of wildlife watchers report a Diadem Rain Frog in Yasuní National Park on a given day, against under 5% in April, June–July and October, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Diadem Rain Frog sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Yasuní National Park, in our data
Yasuní National Park is the only park on Wallace's Line with enough records to rate Diadem Rain Frog sightings: about 20% of wildlife watchers there report one on a given day.
Same genus: Pristimantis

GBIF citizen-science records
It is estimated from how often the Diadem Rain Frog is recorded against all the amphibians logged in Yasuní National Park (16 verified sightings from 2019 to 2026), 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.
