Did you know cities harbor about 20% of the world’s bird species? Cities provide crucial stopover habitat for migrating birds, but problems like light pollution and shrinking green spaces pose a deadly threat. 

To broaden our understanding, the Cornell Lab of Ornithology’s Team Sapsucker hopes to see lots of urban birds when they head to New York City on May 14 for Big Day! 

Part fundraiser, part 24-hour birding marathon, Big Day supports and informs our conservation efforts—and your support helps make it a success!
