Christmas Bird Count (CBC)

Coming again in late 2025


Watch the teams in action during our 2022 Christmas Bird Count!

JOIN THE COUNT FOR FUN AND SCIENCE

The EAS CBC is an all-volunteer project, and we have three ways for you to participate.

  • Join a team: Teams are led by experienced birders who are accepting 3-8 volunteer participants.

  • Feeder Watcher: We also support at-home feeder watchers who count birds at their home feeder or other locations within the 25-mile diameter circle centered on Beaver Lake in Sammamish.

    • View our CBC Count Circle here and see if your address falls inside the circle (top left for search field).

    • If you are interested in becoming a Feeder Watcher, please send an email to Andy at amccormick@eastsideaudubon.org. You will receive guidelines and instructions before the count day.

  • CBC Zoom Social: Everyone, whether birding or not, is invited to join the CBC Zoom social after the count.

BIRD COUNT HISTORY

The CBC is the world’s largest and longest-running community science data collection project. The 2024-2025 count period from December 14 to January 5 marks the 125 th CBC sponsored by the National Audubon Society. It will be Eastside Audubon’s 41 st CBC.

The Christmas Bird Count began in 1900, when conservationists sought to re-direct what had been an annual contest to see who could kill the most birds during the Christmas holiday, to an annual census of birds. Despite the name, the CBC has no affiliation with Christmas and everyone over the age of 18 is welcome to participate in the CBC bird survey.

All results are tallied by a count compiler and submitted to the National Audubon Society. The valuable data gathered on wintering bird populations will support important research like the 3 Billion Birds report and other scientific publications. We report the key findings from the Eastside Audubon count in our newsletter, The Corvid Crier.

Please contact Andy McCormick with any questions or comments about the event, at amccormick@eastsideaudubon.org, or 425-518-0892.
