Pelophylax kurtmuelleri
In 3 days ~50% in a week ~80%
The Balkan frog (Pelophylax kurtmuelleri) also known as the Balkan water frog and Greek marsh frog) is a species of frog occurring in Greece and, to a lesser extent, in Albania, Montenegro, and Serbia. The species highly resembles Pelophylax ridibundus, from which it was only distinguished in 1991 by bio-acoustic analysis. The separation of the species is not unanimously accepted.
The average length is 72 mm for males, 78 mm for females. The back is green or occasionally brown, often with a light green stripe down the middle, and with darker spots irregularly distributed across the back. The tympanum is bronze or green surrounded by a darker color.
The species is found across Greece except in the northeastern corner, where P. ridibundus is found instead. In Western Greece it lives along with Pelophylax epeiroticus. It occurs from sea level up to 1000 m, though large populations are not found above 600 m. Small introduced populations live in Denmark, Poland and Italy. Wikipedia →

Possible
About 20% of wildlife watchers report a Balkan Frog sighting in Athens on a given day, based on 33 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report a Balkan Frog in Athens on a given day, against under 5% in September and December–February, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Balkan 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.
Yes
Of the 2 cities where we can rate Balkan Frog sightings, Athens has the highest daily chance: about 20%. Next come Copenhagen (Denmark, under 5%).
Same order: Anura
The closest relatives of the Balkan Frog that you can see in Athens (order Anura, Frogs and Toads) are Green Toad (about 20%) and European Toad (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Balkan Frog is recorded against all the amphibians logged in Athens (33 verified sightings), 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.
