The natterjack toad (Epidalea calamita) is a toad native to sandy and heathland areas of Europe. Adults are 60–70 mm (2.4–2.8 in) in length, and are distinguished from common toads by a yellow line down the middle of the back and parallel paratoid glands. They have relatively short legs, which gives them a distinctive gait, contrasting with the hopping movement of many other toad species.
Natterjacks have a very loud and distinctive mating call amplified by the single vocal sac found under the chin of the male. Natterjacks live for up to 15 years, and feed mainly on insects, especially beetles. At night, they move around open terrain with sparse vegetation, and their tracks can often be seen in loose sand. They move considerable distances each night, enabling the species to colonize new habitats shut up.
The natterjack toad spawns between the end of April and July, laying strings of eggs in shallow, warm pools. Because the natterjack toad is often present in low numbers, its loud mating calls are important so that the sexes can find each other.
Natterjacks can only spawn in pools that have a very slightly sloping bottom, and tolerate only sparse... Wikipedia →

Possible
About 30% of wildlife watchers report a Natterjack Toad sighting in Doñana National Park on a given day, based on 47 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 6 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
January and March–April
In those months about 40% of wildlife watchers report a Natterjack Toad in Doñana National Park on a given day, against under 5% in July to September, the lowest months. Those are among Doñana National Park's wettest months, with about 55 mm of rain a month against almost none in July.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Natterjack Toad sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 8 parks where we can rate Natterjack Toad sightings, Doñana National Park has the highest daily chance: about 30%. Next come Monfragüe National Park (Spain, about 30%) and Sierra de Guadarrama National Park (Spain, about 20%).
Same order: Anura
The closest relatives of the Natterjack Toad that you can see in Doñana National Park (order Anura, Frogs and Toads) are Iberian Green Frog (about 30%), Mediterranean Tree Frog (about 20%) 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 Natterjack Toad is recorded against all the amphibians logged in Doñana National Park (47 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.
