In noisy conditions, several avian species modulate their songs in amplitude and in the temporal or frequency domains, presumably to improve communication. Most studies on how passerine birds perform such adjustments have been carried out in oscines, a group well known for the importance of learning in the development of their songs. On the other hand, suboscines, in which learning appears to have little influence on the development of their songs, have been largely neglected. We evaluated song… 

European Blackbirds Exposed to Aircraft Noise Advance Their Chorus, Modify Their Song and Spend More Time Singing

Noise pollution has a strong impact on wildlife by disrupting vocal communication or inducing physiological stress. Songbirds are particularly reliant on vocal communication as they use song during

No reliable evidence for immediate noise-induced song flexibility in a suboscine

Vermilion flycatchers, a suboscine, sing songs with more elements in territories with higher urban noise levels. We tested the hypothesis that this pattern is achieved through vocal flexibility, by

Habitat-related differences in song structure and complexity in a songbird with a large repertoire

These findings may be an example of adaptation of acoustic communication in noisy urban environments, but the need for further investigation into the relationships between birdsong and habitat characteristics, male quality, population density and ambient noise level in populations occupying urban and nonurban habitats is emphasized.

More than noise: light, moon phase, and singing behavior in a passerine

This study highlights the importance of considering several pollutants along with moon phase to better understand how they influence animal signals, links light at night with birdsong structure, and provides additional evidence of a circa-lunar rhythm of song output.

Disentangling Relations among Repertoire Size, Song Rate, Signal Redundancy and Ambient Noise Level in European Songbird

The results support the antiexhaustion hypothesis because males with larger repertoires were able to sing with a significantly higher rate due to faster switching between different song types and producing shorter bouts.

Urban Noise Restricts Song Frequency Bandwidth and Syllable Diversity in Bananaquits: Increasing Audibility at the Expense of Signal Quality

Anthropogenic noise can interfere with animal behavior through masking of acoustic communication. In response to masking, animals may change their acoustic signals as an apparent adjustment strategy,

The presence of both high- and low-frequency ambient noise may make it difficult for urban birds to avoid signal masking while still maintaining their fitness in noisy cities.




Abstract In urban environments, anthropogenic noise may mask bird song, especially the notes occurring at lower frequencies (1–2 kHz). Birds living in urban environments may modify their songs,

Immediate spectral flexibility in singing chiffchaffs during experimental exposure to highway noise

It is shown that chiffchaffs along noisy highways also sing with a higher minimum frequency than chiffChaffs nearby at a quiet riverside, and that these birds are capable of making such adjustments over a very short time scale.

Strategies of song adaptation to urban noise in the house finch: syllable pitch plasticity or differential syllable use?

This work explored both strategies in the Mexico City population of house finch, a species known to possess a repertoire of several hundreds of syllable types, and provided evidence of syllability pitch plasticity.

Variation in the song of a sub-oscine, the vermilion flycatcher

Songs of 12 territorial males of a Central Mexican population of the vermilion flycatchers are recorded, finding that both song structure and performance showed substantial seasonal and inter-individual variation, and some possible functions of this variation are discussed.

Low-frequency songs lose their potency in noisy urban conditions

It is experimentally shown that urban noise conditions impair male–female communication and that signal efficiency depends on song frequency in the presence of noise, and that low-frequency songs by males are related to female fertility as well as sexual fidelity.

A behavioural mechanism explaining noise-dependent frequency use in urban birdsong


It is suggested that, depending on the species-specific nature of the sexual selection process in relation to the sender songs, ambient noise may impair the probability of reproduction to different degrees in different species.

Different behavioural responses to anthropogenic noise by two closely related passerine birds

Investigation of the influence of noise on habitat occupancy rates and vocal frequency in two congeneric vireos with similar song features found that vocal plasticity may help some species occupy noisy areas, but because there were no commonalities among the signal changes exhibited by these closely related birds, it is difficult to predict how diverse species may modify their signals in an increasingly noisy world.
