About the Christmas Bird Count

Annual Christmas Bird Counts, sponsored by the National Audubon Society and conducted by volunteers, are held throughout the U.S., Canada, and many countries throughout the Western Hemisphere. The counts attempt to record every individual bird encountered within a defined 15-mile diameter — about 177 square miles — during one calendar day. Collectively, the Christmas Bird Counts are the largest and longest running citizen science project in the world, and the data from the CBCs have been used in numerous scientific studies.

The San Francisco count circle includes the north tower of the Golden Gate Bridge and all of San Francisco, and reaches down the peninsula to San Bruno Mountain and the wetlands north of the San Francisco International Airport. Also blessed with a wide variety of habitats, the San Francisco count generally tops 160 species. View a MAP of our San Francisco count areas.
