Physalaemus biligonigerus is a species of frog in the family Leptodactylidae. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. This frog lives in grasslands not far from water. In Brazil, this frog has been found in Cerrado and Pampa biomes. This frog has shown some tolerance to anthropogenic disturbance. Scientists have seen it between 0 and 1,400 m (0 and 4,593 ft) above sea level.
Scientists have reported the frog in protected places: Parque Estadual Itapeva, Parque Nacional da Lagoa do Peixe, and Reserva Biológica Lami Jose Lutzenberger. The male frog perches near or in the water and calls to the female frogs. The female frog deposits her eggs in a spherical foam nest that floats on top of the water. The female frogs are notably fecund, producing many hundreds of per individual per year.
The IUCN Red List and the Red Lists of Uruguay and Paraguay all classify this species as not in danger of extinction. In some places, it is in some danger from water pollution and habitat loss. For example, in Argentina, people convert the Chaco to make farmland and extract wood for use. This frog has been seen on the international... Wikipedia →

With luck
About 10% of wildlife watchers report a Weeping Frog sighting in Cordoba on a given day, based on 10 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a Weeping Frog in Cordoba on a given day, against under 5% in April–October and December, the lowest months. That is one of Cordoba's wettest months, with about 110 mm of rain against 5 mm in August.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Weeping Frog sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Cordoba, in our data
Cordoba is the only city on Wallace's Line with enough records to rate Weeping Frog sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Weeping Frog is recorded against all the amphibians logged in Cordoba (10 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.
