Physalaemus cuvieri is a species of frog in the family Leptodactylidae. It is found in Argentina, Brazil, Paraguay, and possibly also Bolivia, Guyana, Uruguay, and Venezuela. This nocturnal frog lives in forests, savannah, flooded grassland, and livestock pasture. Scientists have seen it between 0 and 2,000 m (0 and 6,562 ft) above sea level. Scientists have reported the frog in protected places.
These frogs reproduce in temporary ponds, puddles, and even cow footprints. The adult frog builds a foam nest for the eggs, which adheres to the base of a blade of grass near the edge of the water. The IUCN classifies this frog as least concern of extinction. What threats it faces include habitat loss, such as the loss of Argentina's Chaco in favor of farms and wood extraction. In other areas water pollution from agricultural runoff affects the frogs. Fires used for land conversion for the creation and improvement of cattle pasture affect the frogs. In Venezuela, gold mining and its many resulting ecological issues affect the frog. Wikipedia →

With luck
About 10% of wildlife watchers report a Cuvier’s Foam Frog sighting in Curitiba on a given day, based on 9 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January
In that month about 30% of wildlife watchers report a Cuvier’s Foam Frog in Curitiba on a given day, against under 5% in February, April–August and December, the lowest months. That is one of Curitiba's wettest months, with about 220 mm of rain against 75 mm in August.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Cuvier’s Foam Frog sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Yes
Of the 5 cities where we can rate Cuvier’s Foam Frog sightings, Curitiba has the highest daily chance: about 10%. Next come Fortaleza (Brazil, about 10%) and Maceió (Brazil, about 10%).
Same order: Anura
The closest relatives of the Cuvier’s Foam Frog that you can see in Curitiba (order Anura, Frogs and Toads) are Yellow Cururu Toad (about 40%), Bischoff's Tree Frog (about 20%) and Boie's Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cuvier’s Foam Frog is recorded against all the amphibians logged in Curitiba (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.
