Every December, hundreds of Bay Area birders take part in Golden Gate Bird Alliance’s Christmas Bird Counts (CBCs). From before dawn until dusk, they trek through parks, neighborhoods, and wetlands, venture out in boats on the bay, and skirt reservoirs and bayside mudflats to identify the species and count the numbers of birds at every site.
Spend a fun day outdoors counting individual birds and species, and contributing to our understanding of bird populations! Both beginners and experienced birders welcome. You can participate as a field observer with a pre-assigned territory, or as a feeder watcher from the comfort of your own home!
Each count day culminates with an optional festive CBC dinner ($35) where final counts are tallied and stories exchanged about rare bird sightings and locations.
Golden Gate Bird Alliance is sponsoring the following THREE counts in winter 2023:

The Annual Christmas Bird Count, sponsored by the National Audubon Society and conducted by volunteers, is the nation’s longest running citizen science bird project. Between mid-December and early-January, counts held annually throughout North America attempt to record every individual bird observed within a defined 15-mile diameter — about 177 square miles — during one calendar day.
