“…Dumyahn and Pijanowski (2011) argue that soundscapes have value worthy of conservation. Data processing methods have recently been established to characterize sounds from different sources (e.g., biotic, abiotic, and anthropogenic) for acoustic habitat monitoring to detect changes in soundscapes (Merchant et al 2015).…”

ABSTRACT. Acoustic surveys are a widely used sampling tool in ecological research and monitoring. They are used to monitor populations and ecosystems and to study various aspects of animal behavior. Autonomous recording units (ARUs) can record sound in most environments and are increasingly used by researchers to conduct acoustic surveys for birds. In this review, we summarize the use of ARUs in avian ecological research and synthesize current knowledge of the benefits and drawbacks of this technology. ARUs enable researchers to do more repeat visits with less time spent in the field, with the added benefits of a permanent record of the data collected and reduced observer bias. They are useful in remote locations and for targeting rare species. ARUs are mostly comparable to human observers in terms of species richness, but in some cases, they detect fewer species and at shorter distances. Drawbacks of ARUs include the cost of equipment, storage of recordings, loss of data if units fail, and potential sampling trade-offs in spatial vs. temporal coverage. ARUs generate large data sets of audio recordings, but advances in automated species recognition and acoustic processing techniques are contributing to make the processing time manageable. Future applications of ARUs include biodiversity monitoring and studying habitat use, animal movement, and various behavioral ecology questions based on vocalization activity. ARUs have the potential to make significant advances in avian ecological research and to be used in more innovative ways than simply as a substitute for a human observer in the field. Unités d'enregistrement autonomes en écologie aviaire : utilisations actuelles et futuresRÉSUMÉ. Les relevés acoustiques sont largement employés comme outil d'échantillonnage pour la recherche et les suivis écologiques. Ils sont utilisés pour suivre les populations et les écosystèmes et étudier le comportement animal sous divers angles. Les unités d'enregistrement autonomes (ARU, pour autonomus recording units) peuvent enregistrer les sons dans la plupart des environnements et sont utilisés de plus en plus souvent par les chercheurs pour effectuer des relevés acoustiques d'oiseaux. Dans la présente revue, nous résumons l'utilisation d'ARU en écologie aviaire et synthétisons les avantages et désavantages connus de cette technologie. Les ARU permettent aux chercheurs de faire plus de visites répétées tout en passant moins de temps sur le terrain, avec l'avantage d'avoir un enregistrement permanent des données récoltées et de réduire le biais associé à l'observateur. Ils sont utiles en milieu éloigné et dans les cas où on cible des espèces rares. Les ARU sont comparables aux observateurs humains pour ce qui est de la richesse spécifique, mais dans certains cas, ils détectent moins d'espèces et à des distances plus courtes. Les désavantages des ARU comprennent le coût de l'équipement, la sauvegarde des enregistrements, la perte de données en cas de défaillance des unités, et le compromis possible à devoir faire sur le plan de la...

“…In all these disciplines, soundscape has typically referred to the totality of the sounds occurring at any location within a certain time frame, including those that are biological, geophysical, and anthropic. While the concept of the soundscape was grounded in the early works of Southworth (1969), an environmental psychologist, and Schafer (1994), a musician, it has recently been championed as a means of ecological analysis (Dumyahn and Pijanowski 2011, Pijanowski et al 2011a, 2011b, Farina 2014, Smith and Pijanowski 2014, Lomolino et al 2015. Indeed, acoustic communication is crucial for many organisms to reproduce, feed, defend territories, and avoid predators (Kroodsma 1982, 2005, Templeton and Greene 2007.…”

“…The use of acoustic tools in biodiversity conservation is not new (Batista and Gaunt, 1997), but it has recently increased, especially as part of the management of large wild areas (Dumyahn and Pijanowski, 2011;Farina, 2014;Laiolo, 2010). There is a growing demand from park managers and local decision-makers to better understand acoustic sampling design and the automated analysis of sound.…”
