The mere fact that amphibians sing, especially frogs, is widely known.

Frogs in biological pools are no exception. But why do they sing?

The season of most concert activity is obviously spring. For many of the species there is a direct link between water temperature and song intensity. Singing takes a lot of energy and it’s exclusively the males who sing. The content of the song is more or less always the same and translatable with “I’m the best around here and it’s really worth mating with me“. But there are also other contents. When we hear the green frogs singing, sometimes there is a loud scream, much shorter than the normal song. This scream is emitted when a male grabs another male. This error is quickly corrected by such a short, loud phrase in the chant, meaning “Stay away from me, I’m a male too!”

So it’s already pretty clear: singing is a prenuptial activity. Depending on each species of amphibian, the song season is short or long and takes place at different times of the year. The biggest “noise” are the frogs and the green frogs (pictures). Frogs sing very little, so only specialists can notice the sound activities of these species.
