A groundbreaking research project at the University of Windsor is currently monitoring the nocturnal migration of birds across Canada in real-time. Graduate students Natalie Emerick and Madison Bygrove have deployed 100 acoustic recorders spanning from Vancouver Island to Newfoundland to capture and categorize bird sounds using advanced AI technology called Motus Audio.
The small 3D-printed box recorders contain microphones that capture bird calls as they communicate and navigate through the night sky. This research initiative aims to shed light on nocturnal bird behaviors that have been challenging to observe and document in the past.
Emerick highlighted the significance of this project as it explores nocturnal bird migration patterns in eastern Canada, an area where such research has been lacking. The duo has engaged a diverse network of participants, including volunteers and experts, to host the recorders in various locations, enabling a comprehensive monitoring of bird migration pathways.
One area of focus for the researchers is investigating the impact of artificial night light on bird behavior. They are particularly interested in how birds utilize calls to navigate in areas with different light levels, indicating possible disorientation caused by excessive artificial lighting.
The researchers are optimistic about the insights they will gain during the upcoming fall migration season as they refine their data analysis techniques. The Motus Audio technology, initially developed with government funding, has enabled a nationwide “audio curtain” capturing bird movements across Canada.
Ecologist Ryan Norris, who supports the project by hosting acoustic devices, emphasized the importance of this research in monitoring bird populations, especially in remote areas like the Canadian boreal forest. The AI model used in the study aids in identifying bird species based on their unique sounds, contributing to a better understanding of bird migration dynamics.
Norris expressed excitement about the potential of this research to provide valuable data on bird movements throughout different seasons, offering new insights into the factors influencing bird populations. This innovative approach could help address conservation challenges by uncovering critical information about bird declines and migration patterns.
