An altered acoustic environment can have severe consequences for natural communities; especially for species that use acoustic signals to communicate and achieve breeding success. Numerous studies have focused on traffic noise disturbance; but the possible causes of road effects are inter-correlated and the literature on noise qua noise is sometimes contradictory. To provide further empirical data in this regard; the authors investigated the spatio-temporal variability of the singing dynamics of an avian community living in an acoustic context altered by traffic noise. Fieldwork was carried out in a wood of Turkey oaks (central Italy) bordered on one side by a main road. The soundscape was examined by positioning eight digital recorders; distributed in two transects perpendicular to the road; and recording between 6:30 and 8.30 a.m. for 12 continuous sessions. The acoustic complexity index was used to obtain a quantification of singing dynamics; which were positively correlated with traffic noise. This may indicate that birds try to propagate their signals with greater emphasis (e.g; amplified redundancy or loudness of the songs) to override the masking effect of noise. Nevertheless; an ecotonal effect could have influenced the correlation results; with this enhanced dynamic possibly being due to a more densely populated environment. © 2013 Acoustical Society of America;
