Christmas Bird Count (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 is welcome to participate in the CBC bird survey.

Eastside Audubon’s CBC

Eastside Audubon's big day of birding for science is December 14th, 2019. Count birds on your own or as part of an Eastside Audubon team from early morning through late afternoon, then join us for a celebration dinner from 4:30 pm to 6 pm in the lower level of the Northlake Unitarian Universalist Church in Kirkland.

More details about this year’s event will be released in the coming weeks.

  1. Explore the trip descriptions and choose the one where you want to bird for the CBC.

    • Whether you're willing to drive

    • Second and third choice of count areas, if you like

  3. Leaders will fill their teams on a first-come, first-served basis. If your first-choice team fills up, the leader will pass your information on to Andy McCormick. Andy will get you on another route and let you know.

  4. A few days before CBC count day on December 14th, the leader of your area will contact you to confirm where and when to meet, whether or not you're driving (tank full when you start), and what to wear and bring.

  2. List the names of the bird species you see and tally the number of each (e.g., American Robins – 20; Hermit Thrush – 2).

  3. Before 5 p.m. on December 14, submit your results via a Google Form. Form link and directions will be provided leading up to the event.


CBC Dinner

At the end of our count day on December 14th, we'll tally the results during our traditional CBC dinner. It starts at 4:30 p.m. in the chapel immediately next to Northlake Unitarian Universalist Church, 308 Fourth Ave S, Kirkland, WA 98033.

The chapter will provide appetizers, a hot main course, beverages, and dessert. The dinner is free for all who participate in the bird count.

RSVP: A link will be provided to participants leading up to the event.


What Happens to Our Count Data

Along with hundreds of Audubon chapters nationwide, we send our tallies to National Audubon for compilation. Throughout the year, scientists use the results to study bird distribution and population trends and identify conservation priorities.
