Automated system better at birdwatching than humans

摘要

Bioacoustic recorders could provide vital information to help protect rare and endangered birds such as the European nightjar, says Newcastle University. A Newcastle study found that remote survey techniques were twice as effective at detecting rare birds as conventional survey methods. Using automated equipment to record the nightjars at dawn and dusk, when they are most active, the team achieved a 217% increased detection rate over those carried out by specialist ornithologists.
