Frogs have different types of call to suit different occasions

Frogs have different types of call to suit different occasions, a new study finds. It was known that birds sing different songs depending on context, yet this kind of behaviour has not been documented among the so-called simpler animals, the anurans (frogs and toads).

This study, conducted by researchers from Indian Institute of Science (IISc), Bengaluru, and Indian Institute of Science Education and Research (IISER), Pune, has been published in the journal Animal Behaviour.

The group studied two species of frog – Humayun’s Night Frog (Nyctibatrachus humayuni) and Amboli Bush Frog (Pseudophilautus amboli). Both species of anurans are endemic to the Western Ghats.

While N. humayuni produces calls with two notes (ascending and descending), P. amboli produces calls with six-note types.

This is the first study to examine “sequences” of vocalisations in frogs.
