The Christmas Bird Count (CBC) is the world's longest-running citizen science project, organized by the National Audubon Society, where volunteers count birds within 15-mile circles from December 14 to January 5 to monitor population health, migration, and climate change impacts, providing crucial data for conservation efforts and revealing trends like significant bird loss since 1970 or range shifts due to warmer winters.
