Likely
About 50% of wildlife watchers report an Iberian Green Frog sighting in Monfragüe National Park on a given day, based on 91 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 10 amphibians we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
April
In that month about 60% of wildlife watchers report an Iberian Green Frog in Monfragüe National Park on a given day, against about 10% in December and January, the lowest months. That is one of Monfragüe National Park's wettest months, with about 70 mm of rain against almost none in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Iberian Green 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.
Yes
Of the 5 parks where we can rate Iberian Green Frog sightings, Monfragüe National Park has the highest daily chance: about 50%. Next come Sierra Nevada National Park (Spain, about 30%) and Aigüestortes National Park (Spain, about 30%). All parks ranked.

GBIF citizen-science records
It is estimated from how often the Iberian Green Frog is recorded against all the amphibians logged in Monfragüe National Park (91 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.
