Wind‐robust sound event detection and denoising for bioacoustics [PDF]
Methods in Ecology and Evolution, 2021 Sound recordings are used in various ecological studies, including wildlife monitoring by acoustic surveys. Such surveys often require automatic detection of target sound events in the large amount of data produced.

Chaos in a bioacoustic signal [PDF]
The Journal of the Acoustical Society of America, 1991 Zebra finches (Poephila guttata) emit sexually dimorphic, multiharmonic distance calls. These calls exhibit deterministic chaos. This was demonstrated by first digitizing the time series of the calls of five adult birds of each sex, then embedding a stationary portion of each, selecting an appropriate time delay (tau) value, and generating three ...

Aircraft events correspond with vocal behavior in a passerine
Scientific Reports, 2021 Airports can affect birds by hindering acoustic communication. Here, we investigated the impacts of aircraft events on vocal behavior in wood thrush (Hylocichla mustelina) breeding one mile from an airport in Ithaca, NY, USA.

Anomalous Coloration of Indo-Pacific Humpback Dolphins off Southern China
Journal of Marine Science and Engineering, 2023 The Indo-Pacific humpback dolphin is characterized by a particular ontogenic change in body color from dark gray at birth to pure white (or with a few dark-gray spots) after reaching adulthood.

Speeding up training of automated bird recognizers by data reduction of audio features [PDF]
PeerJ, 2020 Automated acoustic recognition of birds is considered an important technology in support of biodiversity monitoring and biodiversity conservation activities. These activities require processing large amounts of soundscape recordings.

Sound and sturgeon: Bioacoustics and anthropogenic sounda).
Journal of the Acoustical Society of America, 2023 Sturgeons are basal bony fishes, most species of which are considered threatened and/or endangered. Like all fishes, sturgeons use hearing to learn about their environment and perhaps communicate with conspecifics, as in mating.

Journal of Marine Science and Engineering, 2022 Small-and-coastal-form Bryde’s whales (Balaenoptera edeni edeni) are known to inhabit coastal and continental shelf waters. However, little is known on their ethological activities, especially underwater behaviours. Here, we deployed a suction cup tag on

Sounding out a continent: seven decades of bioacoustics research in Africa
Bioacoustics, 2022 Bioacoustics has emerged as a useful method of data collection and analysis for diverse animals in a wide range of environments and has helped to describe, monitor, and conserve some of Africa’s species biodiversity.

A Framework for Bioacoustic Vocalization Analysis Using Hidden Markov Models [PDF]
, 1999 Using Hidden Markov Models (HMMs) as a recognition framework for automatic classification of animal vocalizations has a number of benefits, including the ability to handle duration variability through nonlinear time alignment, the ability to incorporate ...
