• •We measured the sound radiation pattern in a poison frog for the first time.•Allobates femoralis presents a nearly omnidirectional sound radiation pattern.•Directionality does not affect the peak frequency of the call in A. femoralis.•Territorial males orient towards the sound source during antiphonal calling. Sound radiation patterns have ecological implications in the effective communication between conspecifics, like optimization of the sound propagation, increase the likelihood to reach mates and to mitigate effects of sound scattering by environmental factors like vegetation. The territorial frog Allobates femoralis advertises its territory against conspecific males and attract females with advertisement calls. Here we report the nearly omnidirectional sound-radiation pattern of the advertisement call of A. femoralis. This sound spreading pattern allows the males to attract mates and repel rivals in all directions. Furthermore, A. femoralis males direct the advertisement call to conspecific neighbours after phonotactic orientation.
