The Feasibility of Counting Songbirds Using Unmanned Aerial Vehicles
, 2017 Obtaining unbiased survey data for vocal bird species is inherently challenging due to observer biases, habitat coverage biases, and logistical constraints.

Remote Sensing in Ecology and Conservation, EarlyView.Vertical‐looking radar provides a first multi‐year analysis of migratory bat phenology in Europe. Bat activity was lowest in winter, increased from spring, and peaked in summer, with similar timing of pre‐ and post‐maternity migrations across years.

Acoustic model adaptation for ortolan bunting (Emberiza hortulana L.) song-type classification [PDF]
, 2008 Automatic systems for vocalization classification often require fairly large amounts of data on which to train models. However, animal vocalization data collection and transcription is a difficult and time-consuming task, so that it is expensive to ...

Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring
Remote Sensing in Ecology and Conservation, EarlyView.Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

Wildlife Biology, EarlyView.Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

Vocal complexity in the long calls of Bornean orangutans [PDF]
PeerJVocal complexity is central to many evolutionary hypotheses about animal communication. Yet, quantifying and comparing complexity remains a challenge, particularly when vocal types are highly graded.

Long-Distance Counter Calling in Maned Wolves: Friends or Foes?
Animals, 2022 Maned wolves (Chrysocyon brachyurus) are monogamous and display biparental care for their young, although adults rarely spend time in close proximity. To better understand vocal interactions of maned wolves over long-distances, we passively recorded >10 ...

Sounds of Soil: A New World of Interactions under Our Feet? [PDF]
, 2019 Soils are biodiversity-dense and constantly carry chemical flows of information, with our mental image of soil being dark and quiet. But what if soil biota tap sound, or more generally, vibrations as a source of information?

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.
