For the past 122 years, teams of enthusiastic birders have joined together every December across North America to participate in the Christmas Bird Count (CBC). Coordinated in the U.S. by National Audubon Society, the CBC is the nation’s longest-running bird-related community science project. This early-winter bird census spans three weeks, from December 14, 2022 to January 5, 2023.
Area counts of the number of individual birds of each species present within each 15-mile diameter CBC circle are tallied over 24 hours on just one of those calendar dates. Data collected from thousands of CBC circles provides an annual snapshot of the status of wintering bird populations throughout the country.
