Urban-associated drivers of song variation along a rural–urban gradient
TLDR
Findings show that although anthropogenic noise may shape urban-associated changes in song, other features of the urban environment may be more important contributors to patterns in song variation.
Noisy human neighbours affect where urban monkeys live
TLDR
It is shown that urban black-tufted marmosets (Callithrix penicillata) living in noisy urban areas may select their home-range based primarily on ambient noise level, providing evidence that the use of home- range by wild animals can be affected by a potential aversive stimulus such as noise pollution.
Singing in the city: high song frequencies are no guarantee for urban success in birds
TLDR
Although song frequency was related to habitat preferences and body size of the species, none of these factors explained the lack of association with urban success, and these high frequencies are apparently no guarantee for the success of bird species in urbanized environments.
Birds and Anthropogenic Noise: Are Urban Songs Adaptive?
TLDR
It is found that frequency changes of urban songs are not very effective in mitigating masking from traffic noise, and an increase in vocal pitch increased communication distance only marginally, while vocal amplitude adjustments had a strong and significantly larger effect.
Signal information of bird song changes in human-dominated landscapes
TLDR
This is one of few studies to investigate signal relationships and potential fitness consequences of song variation in natural urban systems, thereby providing insight into micro-evolutionary processes operating within novel environments.
Increased attenuation and reverberation are associated with lower maximum frequencies and narrow bandwidth of bird songs in cities
As urbanization expands globally, the communication systems of an increasing number of species are affected. Because bird song is a long-distance signal used to attract mates and defend territories,

Geographical Variation in the Song of the Great Tit (Parus major) in Relation to Ecological Factors
TLDR
It is concluded that differences between habitats in climate, body size, perch height, and acoustic competition from other species are unimiportant in accounting for the observed differences in song.

Many animal species use acoustic signals to attract mates, to defend territories, or to convey information that may contribute to their fitness in other ways. However, the natural environment is

TLDR
It is argued that song learning may initially constrain reproductive divergence, while in the later stages of population divergence it may promote speciation, and primarily on species with learned song.

Song repertoires and territory defence in the great tit
TLDR
It is shown that great tit song plays a part in territory maintenance by experiments in which ‘occupied’ territories with loudspeakers after removing resident pairs, and the possibility that repertoires enhance the effectiveness of song as a territorial display was tested.
