With luck
About 10% of wildlife watchers report a Bandeirantes Snouted Tree Frog sighting in Rio de Janeiro on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 6th most-seen of the 11 amphibians we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April, June–September and December
In those months about 10% of wildlife watchers report a Bandeirantes Snouted Tree Frog in Rio de Janeiro on a given day, against under 5% in January–March, May and October–November, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Bandeirantes Snouted Tree 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 Rio de Janeiro, in our data
Rio de Janeiro is the only city on Wallace's Line with enough records to rate Bandeirantes Snouted Tree Frog sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Hylidae

GBIF citizen-science records
It is estimated from how often the Bandeirantes Snouted Tree Frog is recorded against all the amphibians logged in Rio de Janeiro (9 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.
