Warszewitsch's frog (Lithobates warszewitschii) is a species of frog in the family Ranidae found in Honduras, Nicaragua, Costa Rica, and Panama. L. warszewitschii is medium-sized: males grow to 52 mm (2.0 in) and females to 63 mm (2.5 in) in snout–vent length. The snout is pointed. They have large or small green patches on a golden brown background on their backs; the colouration darkens to brown along the sides. The dark area extends forward onto the face to form a "mask". They also have a light lip line. The dorsolateral folds have lighter colouration, usually golden or yellow. The feet are extensively webbed.
Its natural habitats are humid lowland, montane, and gallery forests, where it is found near streams, but it can also be found far from streams. It can survive even in small forest patches. Some populations seem to have suffered from chytridiomycosis, but more recently recovered. It is also affected by habitat loss.

With luck
About 10% of wildlife watchers report a Warszewitsch's Frog sighting in San José on a given day, based on 40 verified sightings from GBIF citizen-science data. It is the 3rd most-seen of the 8 amphibians we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
May to October
In those months about 20% of wildlife watchers report a Warszewitsch's Frog in San José on a given day, against under 5% in March and April, the lowest months. Those are among San José's wettest months, with about 230 mm of rain a month against 20 mm in February.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Warszewitsch's Frog sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only San José, in our data
San José is the only city on Wallace's Line with enough records to rate Warszewitsch's 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 Warszewitsch's Frog is recorded against all the amphibians logged in San José (40 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.
