Males' calls carry information about individual identity and morphological characteristics of the caller in burrowing petrels
International audience Acoustic communication in burrowing petrels has been poorly studied. However, as for many other bird species, acoustic communication seems to play an essential role in social interactions during the breeding season of these seabirds. Bachelor males call from their burrow, like...
