From radar blobs to bird species, AI helps transform migration tracking
How can we identify specific bird species as they undertake their annual migrations? In the U.S., scientists have long relied on weather radar data to track flocks of birds migrating across the country. But that came with a caveat: the birds appeared as blobs on the radar, much like dark clouds. They couldn’t tell what […]
Scientists in the United States have long used weather radar data to track bird migrations across the country. However, this method has a limitation: the radar displays birds as blobs, making it impossible to identify specific species. A new tool called BirdFlow is addressing this issue by integrating citizen science observations, weather data, and artificial intelligence.
This innovative technology enables researchers to identify and predict the migration routes of specific bird species, providing valuable insights for conservation efforts and aviation management.
The BirdFlow system was developed as a collaborative effort between Cornell University, the University of Massachusetts, and the University of Illinois Urbana-Champaign. In two studies published in the journals Global Ecology and Biogeography and Movement Ecology, the researchers demonstrated the effectiveness of BirdFlow in distinguishing between species during their transcontinental migrations.
Yuting Deng, a co-author of both studies and a postdoctoral researcher at the Cornell Lab of Ornithology, explained that BirdFlow can be used to track individual species, such as the Wilson's warbler, which winters in Alaska. By understanding the migration patterns and timing of different populations, scientists can gain crucial information about the routes taken by these birds.
This knowledge is vital for several reasons. First, it allows conservationists to monitor threatened species and determine when and where they might be moving. Additionally, the data generated by BirdFlow can assist aviation managers in tracking larger bird species that could pose potential hazards to aircraft. Overall, BirdFlow represents a significant advancement in the field of bird migration tracking, providing a more precise and comprehensive understanding of these remarkable creatures' movements.
