The CBC database is the repository of early winter bird observations recorded since 1900. Currently there are over 2100 count circles submitted each year (as of 2008). The database provides information for compilers, regional editors, Audubon conservation staff, ornithologists, academic researchers, federal, state and local wildlife and land planning agencies, educators, birders, chapters, ornithological societies, and the general public to learn about citizen science, bird distribution and population trends.
