Christmas Bird Count
Started in 1900, the Christmas Bird Count (CBC) is North America’s longest-running Citizen Science project. People in more than 2000 locations throughout the Western Hemisphere participate in the CBC each year.
The information collected by thousands of CBC volunteer participants forms one of the world’s largest sets of wildlife survey data. The results are used by conservation biologists, environmental planners, and naturalists to assess the population trends and distribution of birds.
The CBC in each Count Circle is planned on a day between December 14 and January 5. Effort for each circle is organized by a Compiler, who is a fellow volunteer (or team of volunteers) at the local level, often supported by a birding club or naturalist organization.
