Darwin's frog (Rhinoderma darwinii), also called the Southern Darwin's frog, is a species of frog of the family Rhinodermatidae. It was discovered by Charles Darwin during his voyage on HMS Beagle on a trip to Chile. In 1841, French zoologist André Marie Constant Duméril and his assistant Gabriel Bibron described and named Darwin's frog. The diet of R. darwinii consists mostly of herbivore invertebrates. R. darwinii is currently classified as an endangered species by the International Union for Conservation of Nature.
Darwin's frog has an unusual method of brooding, in which the male will facilitate development of its tadpoles inside its vocal sac. This male brooding may make R. darwinii unique among extant frog species, as the only other frog that has this behavior is the R. rufum (northern Darwin's frog), which has been presumed extinct since 1981.
Darwin's frog is a small species with a snout–to–vent length of 2.2 to 3.1 cm (0.9 to 1.2 in). The snout is elongated into a fleshy proboscis which gives the head a triangular shape. The limbs are relatively long and slender. The front feet are not webbed, but some of the toes on the back feet usually are... Wikipedia →

Possible
About 20% of wildlife watchers report a Darwin's Frog sighting in Vicente Pérez Rosales National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January and February
In those months about 30% of wildlife watchers report a Darwin's Frog in Vicente Pérez Rosales National Park on a given day, against under 5% in March to November, the lowest months. Those are among Vicente Pérez Rosales National Park's driest months, with about 90 mm of rain a month against 490 mm in June.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Darwin's Frog sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Vicente Pérez Rosales National Park, in our data
Vicente Pérez Rosales National Park is the only park on Wallace's Line with enough records to rate Darwin's Frog sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Darwin's Frog is recorded against all the amphibians logged in Vicente Pérez Rosales National Park (9 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.
