'Tis the Season for the Christmas Bird Count
On a calendar, Christmas might appear as one day, but if you are a bird watcher, the Audubon Society’s annual Christmas Bird Count (CBC) is actually a twenty-three day event. The CBC is one of the world’s oldest and longest-running citizen science efforts. Now in its 116th year, the count takes place from December 14 to January 5. It is organized into circles, and each circle counts as many birds as possible on one day, either on a predetermined route, or at their backyard bird feeder. Data is compiled, and used to learn about long-term bird trends. The data collected has been used in many reports and publications, such as the State of the Birds Report, which the Service produces.
