With luck
About 10% of wildlife watchers report an Acre Tree Frog sighting in Manu National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 47th most-seen of the 67 amphibians we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
December
In that month about 30% of wildlife watchers report an Acre Tree Frog in Manu National Park on a given day, against under 5% in March–August and October–November, the lowest months. That is one of Manu National Park's wettest months, with about 250 mm of rain against 60 mm in August.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Acre Tree Frog sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Manu National Park, in our data
Manu National Park is the only park on Wallace's Line with enough records to rate Acre Tree 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 Acre Tree Frog is recorded against all the amphibians logged in Manu National Park (9 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.
