Degradation of rural and urban great tit song: testing transmission efficiency.

PLoS ONE, 2011
Acoustic signals play a fundamental role in avian territory defence and mate attraction. Several studies have now shown that spectral properties of bird song differ between urban and rural environments.

Cross fostering experiments suggest that mice songs are innate. [PDF]

PLoS ONE, 2011
BACKGROUND: Vocal learning is a central functional constituent of human speech, and recent studies showing that adult male mice emit ultrasonic sound sequences characterized as "songs" have suggested that the ultrasonic courtship sounds of mice provide a

Background noise but not urbanization level impacted song frequencies in an urban songbird in the Pearl River Delta, Southern China

Global Ecology and Conservation, 2021
Rapid urbanization has profoundly transformed habitats and increased noise pollution in urban environments. Elevated noise levels may mask acoustic signals of urban-dwelling organisms such as birds.

Maximum frequency of songs reflects body size among male dusky warblers Phylloscopus fuscatus (Passeriformes: Phylloscopidae)

The European Zoological Journal, 2017
Song plays a vital role in communication in songbirds, primarily for territorial defense and mate attraction. Larger animals, having larger vocal organs, produce low sound frequencies more efficiently. Accordingly, the frequency of vocalizations is often

Potential Natural Aromatase Blockers on Enhance the Frequency and Sound Quality of Male Canaries [PDF]

E3S Web of Conferences, 2020
The quality sound of singing birds strongly depends on testosterone. Unfortunately, most of the testosterone will be converted to estradiol by the aromatase enzyme. The study aimed to examine the potential of natural aromatase blockers for increasing the

Fin whale song evolution in the North Atlantic

eLife
Animal songs can change within and between populations as the result of different evolutionary processes. When these processes include cultural transmission, the social learning of information or behaviours from conspecifics, songs can undergo rapid ...

Machine learning and statistical classification of birdsong link vocal acoustic features with phylogeny

Scientific Reports, 2023
Birdsong is a longstanding model system for studying evolution and biodiversity. Here, we collected and analyzed high quality song recordings from seven species in the family Estrildidae.

No evidence of repeated song divergence across multiple urban and non-urban populations of dark-eyed juncos (Junco hyemalis) in Southern California

Royal Society Open Science, 2022
Urbanization can affect species communication by introducing new selection pressures, such as noise pollution and different environmental transmission properties.

Patterns of Song across Natural and Anthropogenic Soundscapes Suggest That White-Crowned Sparrows Minimize Acoustic Masking and Maximize Signal Content.

PLoS ONE, 2016
Soundscapes pose both evolutionarily recent and long-standing sources of selection on acoustic communication. We currently know more about the impact of evolutionarily recent human-generated noise on communication than we do about how natural sounds such

Urbanization Influences on the Song Diversity of the Eurasian Nuthatch (Sitta europaea) in Northeast China

Diversity
The continuous advancement of urbanization and the expansion of cities inevitably have certain impacts on urban wildlife. Birds are a highly visible group of urban wildlife, widely distributed and sensitive to environmental changes.
