The European fire-bellied toad (Bombina bombina) is a species of fire-bellied toad native to eastern parts of mainland Europe, where it can be found near waterbodies such as ponds and marshes. It is known for its red colored belly used to ward off predators, an example of aposematism, and its distinctive "whoop" call.
The European fire-bellied toad is a medium-sized frog, growing up to approximately 5.6 centimetres (2+3⁄16 in). The dorsal coloration can vary from gray to brown to green, while the stomach is red with thick black mottling. The backs of these frogs are covered in warts.
When threatened by a predator, the fire-bellied toad will lift up its arms (sometimes flipping over) to expose its red coloration and show off its toxicity to the potential predator. This is known as Unkenreflex, and is an example of aposematism.
The European fire-bellied toad is found throughout Central and Eastern Europe. More particularly, its range starts in eastern Germany (including eastern Denmark and parts of southern Sweden), and then east to the Volga District of Russia where they are stopped by the Ural Mountains. The frog's most southern range is Bulgaria... Wikipedia →

GBIF citizen-science records
It is estimated from how often the European Fire-Bellied Toad is recorded against all the amphibians logged in Bucharest (10 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.
