Pelophylax kurtmuelleri
In 3 days ~10% in a week ~30%
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 →

Rare
Under 5% of wildlife watchers report a Balkan Frog sighting in Copenhagen on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 9 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May and July–August
In those months about 10% of wildlife watchers report a Balkan Frog in Copenhagen on a given day, against under 5% in June and September–April, 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.
2nd of 2
Of the 2 cities where we can rate Balkan Frog sightings, Copenhagen ranks 2nd at under 5%. The best odds are in Athens (Greece, about 20%).
GBIF citizen-science records
It is estimated from how often the Balkan Frog is recorded against all the amphibians logged in Copenhagen (6 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.
