Morro Bay Christmas Bird Count

Any COVID-19 guidelines specified by SLO County, California, or National Audubon will be followed.

Over 2,500 Christmas Bird Counts are held annually across North America, Latin America, the Caribbean, and the Pacific Islands as part of a continent-wide, citizen-science effort to ascertain the winter distribution and fluctuation in numbers of North American birds. A summary of the 123rd CBC results will be available on the National Audubon Society website, and our local count circle results will be posted on the MCAS website.

The 2022 Morro Coast Audubon Society's 69th Morro Bay Christmas Bird Count will be held on Saturday, December 17th, dawn to dusk, rain or shine! Instead of the traditional annual potluck at SLO Botanical Gardens, the compilation will be a "VIRTUAL potluck" and is scheduled for Monday, December 19th, 7:00 pm.

The count is conducted within a circle, 15 miles in diameter, that is centered at the intersection of Turri Road and Los Osos Valley Road (MORRO BAY CBC SECTOR MAP). The circle is divided into 54 sectors. Many counters are needed to achieve a good count and maintain MCAS's high and nationally-accredited ranking. Our success in the National Ranking has been the result of having lots of people in the field sighting and counting birds within the circle. Only species and numbers of birds seen within this circle and its sectors may be counted.

There is no fee to participate in the CBC and all skill levels are welcome. Registration, opening on November 1st, is required to participate (see below). You are asked to register by December 3rd so that the 54 sectors can be organized in order to provide thorough coverage of the entire circle. After you register your Area Leader, who coordinates multiple sectors, will contact you in early December.

Please realize that you will be part of an important team. We seek specific data on the diversity and population of the birds in our Count Circle. Your efforts are being directed by a group that is responsible for the consistency and quality of the data produced. If there is a sector that you would like to explore but you were not assigned to it for this year's CBC, please plan on birding there after the CBC is completed. We rely on your utmost attention to all you hear and see during the survey in the sector to which you have been assigned.

Audubon members and friends everywhere . . . THANK YOU!
