National Audubon's Christmas Bird Count is the longest running Citizen Science survey in the world. Started by Frank Chapman in Boston and New York in December, 1900, it provides critical data on population trends across North America, Hawai'i, and now areas in Central and South America as well. By participating in a CBC you make an important contribution to conservation. Audubon and other organizations use the data collected to assess the health of bird populations, which helps to guide conservation action.

The Western Sonoma County Christmas Bird Count (CBC) began in 1967. Our 55th Annual West Sonoma County CBC will be on Sunday, January 2, 2022.

Note: The field tally form and the final tally form have both been updated in 2018 to include House Wren and Blue-gray Gnatcatcher, and the final tally sheet includes boxes to fill in the weather for the day. Please discard any previous editions of the tally sheets you may have on your computer.

2022 forms will be uploaded later this year. Older versions are shown below

Audubon article on Frank Chapman's bird count in 1886. He counted the feathers of 40 species of birds on women's hats in Manhattan - the impetus for the Christmas Bird Count.
