The blacksmith tree frog (Boana faber), or smith frog, is a frog species in the family Hylidae. It is found in eastern to southern Brazil, north-eastern Argentina and south-eastern Paraguay. Its natural habitats are tropical humid forests, including forest edges, at elevations of 150–800 m (490–2,620 ft) above sea level. Breeding takes place in temporary and permanent pools (including artificial pools) and slow-moving streams where the frogs make nests.
This is an abundant species throughout its range. Clear cutting of forests remains a threat, whereas the species adapts to selectively logged and second growth forests. It is present in several protected areas. It is not considered threatened by the IUCN. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Blacksmith Tree Frog is recorded against all the amphibians logged in Rio de Janeiro (5 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.
