The Chaco tree frog (Boana raniceps) is a frog species in the family Hylidae found in Argentina, Bolivia, Brazil, Colombia, French Guiana, Paraguay, and Venezuela. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, subtropical or tropical dry lowland grassland, rivers, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, urban areas, and heavily degraded former forests.
These organisms are considered general predators, meaning that they feed on a wide range of prey. They catch their prey using a sit-and-wait foraging technique. They tend to hunt high above the ground in the trees. Wikipedia →

Possible
About 20% of wildlife watchers report a Chaco Tree Frog sighting in Fortaleza on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 7 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.
April and November
In those months about 30% of wildlife watchers report a Chaco Tree Frog in Fortaleza on a given day, against under 5% in February–March, May, July and December, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Chaco 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 Fortaleza, in our data
Fortaleza is the only city on Wallace's Line with enough records to rate Chaco 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 Chaco Tree Frog is recorded against all the amphibians logged in Fortaleza (24 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.
