In vivo assessment of the neural substrate linked with vocal imitation accuracy

open access: yeseLife, 2020
Human speech and bird song are acoustically complex communication signals that are learned by imitation during a sensitive period early in life. Although the brain areas indispensable for speech and song learning are known, the neural circuits important ...

Differential geographic patterns in song components of male Albert’s lyrebirds

open access: yesEcology and Evolution, 2021
Geographic variation in bird song has received much attention in evolutionary studies, yet few consider components within songs that may be subject to different constraints and follow different evolutionary trajectories.

Complexity, Predictability and Time Homogeneity of Syntax in the Songs of Cassin's Vireo (Vireo cassinii). [PDF]

open access: yesPLoS ONE, 2016
Many species of animals deliver vocalizations in sequences presumed to be governed by internal rules, though the nature and complexity of these syntactical rules have been investigated in relatively few species.

Flexibility in motor timing constrains the topology and dynamics of pattern generator circuits

open access: yesNature Communications, 2018
Human speech and bird song requires the generation of precisely timed motor patterns. The authors show that zebra finches can learn to independently modify the duration of individual song segments and find that synfire chain networks are ideally suited ...

Extrapair paternity and the evolution of bird song

open access: yes, 2004
Bird song is usually considered to have evolved in the context of sexual selection. Because extrapair paternity is a major component of sexual selection, mating advantages at the social level for males that produce songs of high quality may be ...

Fifty years of bird song research: a case study in animal behaviour [PDF]

open access: yes, 2003
The growth of bird song research over the past half century has been catalysed by both technical and theoretical advances. The study of mechanisms has largely moved to the neurobiological level, where work on bird song has blossomed.

Are urbanization, biotic and social factors associated with the song frequency and song entropy attributes of three urban syntopic passerines?

open access: yesAvian Research
Urban environments have challenging characteristics for bird acoustic communication. High levels of anthropogenic noise, as well as vegetation structure (e.g., in urban parks), can potentially affect the song frequency characteristics of several bird ...

Deep Transfer Learning-Based Automated Identification of Bird Song.

open access: yesInternational Journal of Interactive Multimedia and Artificial Intelligence, 2023
Bird species identification is becoming increasingly crucial for avian biodiversity conservation and assisting ornithologists in quantifying the presence of birds in a given area.

Testing the Accuracy of a birdNET, Automatic bird song Classifier

open access: yes, 2020
In recent years, automated bird song classification programs have been becoming more common among researchers as a way to study, track, and monitor birds. In our research, we tested the accuracy of one such program called BirdNET.

Classification of bird song syllables using wigner-ville ambiguity function cross-terms [PDF]

open access: yes, 2017
A novel feature extraction method for lowdimensional signal representation is presented. The features are useful for classification of non-stationary multi-component signals with stochastic variation in amplitudes and time-frequency locations.
