An international team of researchers led by the University of East Anglia (UEA) developed a new technique, combining world-leading citizen science bird monitoring data with recordings of individual species in the wild, to reconstruct the soundscapes of more than 200,000 sites over the last 25 years.
Lead author Dr Simon Butler, from UEA’s School of Biological Sciences, explained: “The benefits of nature contact are widespread, from improved physical health and psychological well-being to increased likelihood of participating in pro-environmental behaviour.
“Bird song plays an important role in defining the quality of nature experiences but widespread declines in bird populations, and shifts in species’ distributions in response to climate change, mean that the acoustic properties of natural soundscapes are likely to be changing. However, historical sound recordings don’t exist for most places so we needed to develop a new approach to examine this.”
Annual bird count data from North American Breeding Bird Survey and Pan-European Common Bird Monitoring Scheme sites were combined with recordings for over 1000 species from Xeno Canto, an online database of bird calls and songs, to reconstruct historical soundscapes.
