With luck
About 10% of wildlife watchers report an Usina Tree Frog sighting in Brasilia on a given day, based on 6 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report an Usina Tree Frog in Brasilia on a given day, against under 5% in March–April, July, September–October and December–January, the lowest months. That is one of Brasilia's driest months, with about 10 mm of rain against 220 mm in December.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Usina Tree Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Brasilia, in our data
Brasilia is the only city on Wallace's Line with enough records to rate Usina 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 Usina Tree Frog is recorded against all the amphibians logged in Brasilia (6 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.
