Possible
About 20% of wildlife watchers report a Semi-lined Tree Frog sighting in Recife on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 9 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.
August
In that month about 30% of wildlife watchers report a Semi-lined Tree Frog in Recife on a given day, against under 5% in November to May, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Semi-lined 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 Recife, in our data
Recife is the only city on Wallace's Line with enough records to rate Semi-lined Tree Frog sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Semi-lined Tree Frog is recorded against all the amphibians logged in Recife (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.
