Abstract Animals employ various strategies to minimize the overlap of their vocalizations with other sounds, thereby enhancing effectiveness communication. However, little attention has been given experimentally examining how structure acoustic signal changes in response kinds disturbances soundscape. In this study, I investigated whether male thrush nightingales ( Luscinia luscinia ) adjust singing rate, song frequency, and type different types artificial sounds. While males did not reduce intensity noise, they peak frequency songs—raising it presence low-frequency noise lowering high-frequency noise. These bidirectional were associated selective use phrases from repertoire. The proportion low- was significantly reduced under increased results suggest that disturbing sounds can modify songbird vocalizations, at least short term. Birds may enhance signal-to-noise ratio by selecting repertoire are less affected For species a large repertoire, new transmitted within species-specific range play an important role process cultural transmission.
