Birdsong App Powers Global Bird Conservation

The Merlin bird identification app, developed by the Cornell Lab for Ornithology, is set to significantly boost global bird conservation efforts. An upcoming update will enable users to feed real-time bird identifications directly into eBird, one of the world's largest citizen-science biodiversity databases. This integration is anticipated to greatly aid in the conservation of at-risk bird populations worldwide.

Since 2021, the free Merlin app has utilized machine learning to offer instant audio and image identification of birds. These user-submitted detections will now automatically contribute to eBird's vast collection of over 2 billion bird observation records. This influx of data is crucial for monitoring bird populations and developing effective conservation strategies and ecological management plans.

The app, which identifies 2,066 bird species, has seen substantial growth, with over 40 million downloads in 240 countries. In the UK alone, nearly 2 million people used Merlin in May this year to identify birds. While celebrated for connecting people with nature, some concerns exist regarding potential misidentifications, with recommendations for its use in official surveys varying.

Despite challenges, the data gathered is invaluable. Jessie Barry, a leader of the Merlin project, stated that research teams will address data quality issues. She emphasized that increased data collection, even with potential imperfections, will ultimately enhance the understanding of bird population changes compared to not collecting data at all.
