The agile frog (Rana dalmatina) is a European frog in the genus Rana of the true frog family, Ranidae. This species is fat and has long limbs and a pointy snout. Adult males are rarely larger than 6.5 cm, while females can grow up to 8 cm. Its dorsal surface is light brown, reddish-brown, or light greyish-brown with very little contrast. Triangle-shaped spots reach from the temple to the eardrum, which are dark brown. The underside of the agile frog is white without any spots. During mating season, the males often become dark brown.
The hind legs are unusually long, which allow this species to jump further than other similar frogs - they have been known to jump up to two metres in distance. The pupils are horizontal. The colour of the upper third of the iris (above the pupil) is lighter and gold in coloration. The tympanum is about the size of the diameter of the eye. The gland stripes on the frog's back are not very developed and partially interrupted.
The call is a fairly quiet "rog... rog... rog", and can last for up to 12 seconds, and almost sounds like a clucking chicken. They often also call under water, so the calls can only be heard from... Wikipedia →

Possible
About 20% of wildlife watchers report an Agile Frog sighting in Budapest on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 3rd most-seen of the 5 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report an Agile Frog in Budapest on a given day, against under 5% in July–August and December–February, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Agile Frog sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Among the best
Of the 7 cities where we can rate Agile Frog sightings, Budapest ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Vienna (Austria, about 20%).
GBIF citizen-science records
It is estimated from how often the Agile Frog is recorded against all the amphibians logged in Budapest (22 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.
