Wechselkröte
In spite of the name, this species is native to Italy (where it is present on all territories except for the extreme north-east, south-east and south-west) and Corsica. It was probably introduced to the Balearic Islands in prehistoric times, where it is common but declining. Its formerly extended into Switzerland and there have been (so far) unsuccessful reintroduction attempts in that country. Its range meets that of the similar and closely related European green toad ("B. viridis") in far northeastern Italy and that of the Sicilian green toad ("B. boulengeri siculus") in easternmost Sicily.
