In 3 days ~10% in a week ~20%
Boana prasina is a species of frog in the family Hylidae. It is endemic to southeastern Brazil and is observed in many Brazilian states: Minas Gerais, Rio de Janeiro, and São Paulo, and possibly further south. The common name of Boana prasina is Burmeister's treefrog.
Boana prasina occurs in forested habitats, grasslands, and pastureland at elevations of 800–1,400 m (2,600–4,600 ft) above sea level. These frogs are usually found on vegetation near ponds, pools, and lakes. B. prasina breeding takes place in permanent pools and small streams. The egg clutches of B. prasina are attached to vegetation in the water.
Boana prasina is a common species, although certain populations seem to have disappeared. The species is threatened by water pollution and habitat loss caused by fire. It is present in several protected areas. It was recently discovered that the odor secretions by B. prasina vary based on sex. This observation is interesting because the secretion by either sex are from the same source: mutualism with the bacteria Pseudomonas. Pseudomonas has evolved to produce different levels of particular volatile compounds based on the sex of its host, and it is possible it also plays a role in sex variation during early stages.
Hypsiboas prasinus is also used to refer to this frog. Wikipedia →

Rare
Under 5% of wildlife watchers report a Burmeister's Tree Frog sighting in São Paulo on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 11th most-seen of the 13 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April
In that month about 10% of wildlife watchers report a Burmeister's Tree Frog in São Paulo on a given day, against under 5% in May to March, the lowest months.
Only São Paulo, in our data
São Paulo is the only city on Wallace's Line with enough records to rate Burmeister's Tree Frog sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Burmeister's Tree Frog is recorded against all the amphibians logged in São Paulo (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.
