Monitoring biodiversity with sound: How machines can enrich our knowledge

For a long time, ecologists have relied on their senses when it comes to recording animal populations and species diversity. However, modern programmable sound recording devices are now the better option for logging animal vocalisations. Scientists lead by the University of Göttingen have investigated this using studies of birds as an example. The results were published in the journal Ecological Applications.
