The Mediterranean tree frog (Hyla meridionalis), or stripeless tree frog, is a species of frog found in south-west Europe and north-west Africa. It resembles the European tree frog, but is larger (some females are up to 65 millimetres (2.6 in) long), has longer hind legs, and the flank stripe only reaches to the front legs (often starting at the eyes, not at the nostrils). The croaking resembles that of H. arborea, but it is deeper and slower.
The Hyla meridionalis generally breed from the end of March through the beginning of July; their breeding is dependent on a few variables, including water availability. This tree frog species has a larval period of 15 days.
This frog is found in central and southern Portugal, Spain (from Catalonia to Andalusia and Extremadura), southern France, northern Italy (only Liguria), Morocco, northern Algeria and northern Tunisia. It also has ancient introduced populations in Madeira and the Canary Islands and a recent introduction in Menorca.

Possible
About 20% of wildlife watchers report a Mediterranean Tree Frog sighting in Doñana National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 6 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a Mediterranean Tree Frog in Doñana National Park on a given day, against under 5% in February, July–August and November, the lowest months. That is one of Doñana National Park's driest months, with about 10 mm of rain against 90 mm in October.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Mediterranean Tree Frog sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
4th of 5
Of the 5 parks where we can rate Mediterranean Tree Frog sightings, Doñana National Park ranks 4th at about 20%. The best odds are in Camargue (France, about 40%), Monfragüe National Park (Spain, about 30%) and Cévennes National Park (France, about 30%).
Same order: Anura
The closest relatives of the Mediterranean Tree Frog that you can see in Doñana National Park (order Anura, Frogs and Toads) are Natterjack Toad (about 30%), Iberian Green Frog (about 30%) and Iberian Spadefoot Toad (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mediterranean Tree Frog is recorded against all the amphibians logged in Doñana National Park (20 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.
