Birdsong: Is It Music to Their Ears? [PDF]

Frontiers in Evolutionary Neuroscience, 2012
Since the time of Darwin, biologists have wondered whether birdsong and music may serve similar purposes or have the same evolutionary precursors. Most attempts to compare song with music have focused on the qualities of the sounds themselves, such as melody and rhythm.

Testing the strength and direction of selection on vocal frequency using metabolic scaling theory

Ecosphere, 2021
A major challenge for studies assessing drivers of phenotypic divergence is the statistical comparison of taxa with unique, often unknown, evolutionary histories, and for which there are no clear expected trait values.

The Role of the Learner in the Cultural Evolution of Vocalizations

Frontiers in Psychology, 2021
As a uniquely human behavior, language is crucial to our understanding of ourselves and of the world around us. Despite centuries of research into how languages have historically developed and how people learn them, fully understanding the origin and ...

Investigation of musicality in birdsong [PDF]

Hearing Research, 2014
Songbirds spend much of their time learning, producing, and listening to complex vocal sequences we call songs. Songs are learned via cultural transmission, and singing, usually by males, has a strong impact on the behavioral state of the listeners, often promoting affiliation, pair bonding, or aggression.

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

Wildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Lobbying and Political Risk Disclosure: Do Socially Responsible Firms Voluntarily Disclose More?

British Journal of Management, EarlyView.
Abstract Drawing on theories of strategic communication, legitimacy, impression management and moral capital, this study investigates whether firms use political risk disclosure to offset negative perceptions associated with corporate lobbying. Using a sample of 10,120 observations from 1362 US firms between 2002 and 2018, we find that firms with ...

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

Integrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

SOUPE: An R package to test and optimise the phylogenetic and ecological representativeness of a taxonomic sample

Methods in Ecology and Evolution, EarlyView.
Abstract In the field of evolutionary biology, the selection of a phylogenetically representative sample is a crucial step to have a complete and accurate understanding of the studied group and the evolution of its traits. However, this step is often overlooked, and there is currently no objective way to assess the relevance of a sample for a given ...

Data-efficient self-supervised algorithms for fine-grained birdsong analysis

Ecological Informatics
Research in bioacoustics, neuroscience, and linguistics often uses birdsong as a proxy to acquire knowledge across diverse areas. This requires audio models to annotate and parse the birdsong.
