“…To overcome this problem, animals may adjust their acoustic signals in a variety of different ways, including increasing the duration of brief calls , increasing the redundancy of their vocalisations by producing longer and more repetitive signal series (Brumm and Slater, 2006;Kaiser and Hammers, 2009), shifting the timing of their vocalisations (Fuller et al, 2007;Vargas-Salinas and Amézquita, 2013) or increasing the pitch of their vocalisations (Slabbekoorn and Peet, 2003;Parks et al, 2007). One of the most efficient and widespread methods by which animals reduce the impact of signal masking is by raising the amplitude of their vocalisations Hotchkin and Parks, 2013).…”

There was an error published in J. Exp. Biol. 220, 1065-1071.Eqn 2 was displayed incorrectly. The correct equation appears below.We apologise to the authors and readers for any inconvenience this may have caused. ABSTRACTAnimals that use vocal signals to communicate often compensate for interference and masking from background noise by raising the amplitude of their vocalisations. This response has been termed the Lombard effect. However, despite more than a century of research, little is known how quickly animals can adjust the amplitude of their vocalisations after the onset of noise. The ability to respond quickly to increases in noise levels would allow animals to avoid signal masking and ensure their calls continue to be heard, even if they are interrupted by sudden bursts of high-amplitude noise. We tested how quickly singing male canaries (Serinus canaria) exhibit the Lombard effect by exposing them to short playbacks of white noise and measuring the speed of their responses. We show that canaries exhibit the Lombard effect in as little as 300 ms after the onset of noise and are also able to increase the amplitude of their songs midsong and mid-phrase without pausing. Our results demonstrate high vocal plasticity in this species and suggest that birds are able to adjust the amplitude of their vocalisations very rapidly to ensure they can still be heard even during sudden changes in background noise levels.

“…Data on frogs has shown, for example, that anthropogenic noise may either increase or decrease calling activities [40,41], with possible fitness consequences related to increased energetic or predation costs or decreased mating success. While there are no similar data yet for free-living fish, a relatively old study reports on actual interruption of spawning in roach (Rutilus rutilus) and rudd (Scardinius erythrophthalmus) by an approaching fast-moving powerboat [42].…”

“…The association between noise and rattle rate was more robust. Some studies have found different repetition rates of acoustic elements (e.g., songs, elements, pulses) associated with different noise levels: in birds (e.g., Slabbekoorn and Smith 2002;Slabbekoorn and den Boer-Visser 2006), fishes (Picciulin et al 2012), whales (Lesage et al 1999), and frogs (Kaiser and Hammers 2009). It remains to be investigated whether different rattle rates convey a detection advantage in noisy conditions.…”

Some birds in noisy areas produce songs with higher frequency and/or amplitude and altered timing compared to individuals in quiet areas. These changes may function to increase the efficacy of acoustic signals by reducing masking by noise. We collected audio recordings of redwinged blackbirds and measured noise levels. We found that males in noisier places produced songs with fewer syllables and slower repeat rate of elements in some components (rattles). Birds may also improve the efficacy of communication in noise by increasing usage of other signaling modalities. Red-winged blackbirds also perform a visual display in different intensities while singing. We also tested whether this species performs the visual display in different intensities according to current noise levels, and predicted that if the efficacy of songs is impaired in noisy places, males would compensate by performing a more intense visual display. For this, we also collected visual recordings from the same males from which we obtained acoustic recordings. We found no association between acoustic noise and the intensity of the visual display; thus, our results do not support the idea that males are using the visual display as a backup signal to communicate under acoustic noise. We discuss some possible explanations of this negative finding and for the observed noise-related changes in song length and rattle rate in the context of communication under noise.
