The Pyrenean frog or Pyrenees frog (Rana pyrenaica) is a species of frogs in the family Ranidae found in the Pyrenees mountains of France and Spain. Its natural habitats are fast-moving mountain streams and their surroundings. The IUCN lists it as "endangered".
The Pyrenean frog is the smallest species of brown frog in Europe, with adults reaching a snout-to-vent length of about 33 to 45 mm (1.3 to 1.8 in), females being slightly larger than males. The snout is blunt and rounded and the nostrils are more widely separated than are the eye bulges. The tympani are small and not always visible and the dorso-lateral folds are fairly close together. The hind feet are completely webbed apart from the tip of the fourth toe. This frog is creamy-brown, buff, greyish-brown, reddish-brown or olive-grey with rather indistinct blotches of greenish-brown or brown. The hind legs are faintly barred. The upper lip is often noticeably pale and the throat and underparts are whitish with the belly sometimes flushed with yellow or pink, especially under the thighs. It differs from the common frog (Rana temporaria) by being smaller, having a less-pointed snout and less-distinct markings... Wikipedia →

With luck
About 10% of wildlife watchers report a Pyrenean frog sighting in Pyrénées National Park on a given day, based on 119 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 11 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May to August
In those months about 20% of wildlife watchers report a Pyrenean frog in Pyrénées National Park on a given day, against under 5% in October to March, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Pyrenean frog sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Pyrenean frog sightings, Pyrénées National Park ranks 2nd at about 10%. The best odds are in Ordesa y Monte Perdido National Park (Spain, about 20%).
Same genus: Rana
The closest relatives of the Pyrenean frog that you can see in Pyrénées National Park (genus Rana, Pond Frogs) are European Common Frog (about 70%) and Agile Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pyrenean frog is recorded against all the amphibians logged in Pyrénées National Park (119 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.
