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 Iguaçu National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Cuvier’s Foam Frog in Iguaçu National Park on a given day, against under 5% in November to August, the lowest months.
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

GBIF citizen-science records
It is estimated from how often the Cuvier’s Foam Frog is recorded against all the amphibians logged in Iguaçu National Park (7 verified sightings from 2019 to 2026), 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.
