Comparison of semiautomated bird song recognition with manual detection of recorded bird song samples [PDF]

Avian Conservation and Ecology, 2017
Automated recording units are increasingly being used to sample wildlife populations. These devices can produce large amounts of data that are difficult to process manually.

A bird song detector for improving bird identification through deep learning: A case study from Doñana

Ecological Informatics
Passive Acoustic Monitoring (PAM), which uses devices like automatic audio recorders, has become a fundamental tool in conserving and managing natural ecosystems.

Rethinking our assumptions about the evolution of bird song and other sexually dimorphic signals

Frontiers in Ecology and Evolution, 2015
Bird song is often cited as a classic example of a sexually-selected ornament, in part because historically it has been considered a primarily male trait.

Estimating Mutual Information for Spike Trains: A Bird Song Example. [PDF]

Entropy (Basel), 2023
Zebra finch are a model animal used in the study of audition. They are adept at recognizing zebra finch songs and the neural pathway involved in song recognition is well studied.

Cultural conformity generates extremely stable traditions in bird song. [PDF]

Nat Commun, 2018
Cultural traditions have been observed in a wide variety of animal species. It remains unclear, however, what is required for social learning to give rise to stable traditions: what level of precision and what learning strategies are required. We address

Bird population declines and species turnover are changing the acoustic properties of spring soundscapes

Nature Communications, 2021
Birdsong has long connected humans to nature. Historical reconstructions using bird monitoring and song recordings collected by citizen scientists reveal that the soundscape of birdsong in North America and Europe is both quieter and less varied ...

Conceptualising quality early childhood education: Learning from young children in Brazil and South Africa through creative and play‐based methods

British Educational Research Journal, EarlyView., 2023
Abstract Early childhood has increasingly been acknowledged as a vital time for all children. Inclusive and quality education is part of the United Nations Sustainable Development Goals, with the further specification that all children have access to quality pre‐primary education.

Phantom rivers filter birds and bats by acoustic niche

Nature Communications, 2021
An experimental study finds that birds and bats avoid whitewater river noise, and that intense noise reduces bird foraging activity and causes bats to switch hunting strategies.

Predicting bird song from space. [PDF]

Evol Appl, 2013
Environmentally imposed selection pressures are well known to shape animal signals. Changes in these signals can result in recognition mismatches between individuals living in different habitats, leading to reproductive divergence and speciation.

Natural changes in brain temperature underlie variations in song tempo during a mating behavior. [PDF]

PLoS ONE, 2012
The song of a male zebra finch is a stereotyped motor sequence whose tempo varies with social context--whether or not the song is directed at a female bird--as well as with the time of day.
