126th Christmas Bird Count:

126 Years and Counting!

By Patti Langen

History of the CBC

In the late 1800s, the Christmas “Side Hunt” was a holiday tradition. Neighbors divided into teams, shouldered their rifles, and roamed the countryside to shoot any poor creature that flew or ran. At day’s end, the team with the biggest heap of fur and feathers declared victory. But one man, Frank Chapman of the newly founded Audubon Society, imagined a different tradition—one that celebrated life rather than destruction. On Christmas Day, 1900, 27 hardy volunteers braved the winter cold at 25 sites across North America. Their mission: to count every bird they could find, alive and free. From that bold first step, the Audubon Christmas Bird Count (CBC) was born, a new tradition rooted in conservation and care for the natural world.

How does it work?

The Oceanside CBC is one of six CBCs in San Diego County. Each CBC takes place within a 15-mile-diameter circle, which is divided into smaller areas. Every area is led by a team leader who coordinates one or more groups of birders. On count day, rain or shine, teams head out early to record all the birds they see and hear in their assigned section. The information participants gather each year contributes to one of only two major databases that guide ornithologists and conservation biologists in deciding what actions are needed to protect birds and the habitats they depend on. In the afternoon, teams gather at the Nature Center to tally an overall estimate of the day’s species total. This year, the Oceanside CBC will be held on Sunday, December 14.

Who can participate?

Everyone is welcome—no matter your level of birding experience! If you can spot a bird and point it out, you can help! To join this exciting community science project, please email Patti Langen (patti.langenzoo@gmail.com) by November 30. Be sure to include your name, phone number, and a brief note about your birding experience. If you’d like a shorter version of the CBC, we offer a 2.5-hour “mini-CBC” that starts and ends at the Nature Center.

Christmas Bird Count (CBC)

December, 2024 Oceanside Christmas Bird Count results and highlights are below:

The 2024 Oceanside Christmas Bird Count, held on December 29, was a success this year thanks to the 140 participants who generously volunteered their time. Early on, birders were hindered in their efforts to find birds by thick morning fog. Despite the challenges, this year’s CBC species total reached 186 species, which included some rare bird sightings. A Dusky-capped Flycatcher was discovered in a business park in Carlsbad. This was the only record for this species in San Diego County in 2024. Other rarities included an American Redstart found at Buccaneer Park in Oceanside, a Vaux’s Swift spotted in Camp Pendleton, and a returning Solitary Sandpiper at Whelan Lake for its second year. In Carlsbad, CBC teams found a Palm Warbler, a Hermit Warbler, and a Yellow-headed Blackbird.

Other interesting finds were Cackling Geese at Guajome Lake and Libby Lake, a Ruddy Turnstone in Camp Pendleton, Greater Scaup and Yellow-crowned Night Heron at Batiquitos Lagoon, and a Western Flycatcher in Vista. At Camp Pendleton, teams found several rarities, including Northern Rough-winged Swallow, Cactus Wren, and Purple Finch. White-throated Sparrows were reported in both Carlsbad and Oceanside. In South Carlsbad, one birder found a Hooded Oriole, which may have decided that North County was a preferable wintering spot.

Warbler sightings included Nashville Warbler, Yellow Warbler, and Wilson’s Warbler in several locations around Oceanside and Carlsbad. At Buddy Todd Park, participants located a Summer Tanager and a Western Tanager.

Buena Vista Audubon Society hosted the event once again, with Nature Center Manager Annette Schneider and team serving up a delicious lunch for the participants. Paul Lehman skillfully ran the compilation of species seen that day and shared his expertise of the status and distribution of notable species. Joni Ciarletta and Jane Mygatt meticulously reviewed and entered data for the CBC website. A team effort to be sure!

Sincere thanks also to Paul Lehman for conducting the compilation meeting and for Patti Langen for leading the Oceanside Christmas Bird Count.

The CBC takes place during the winter holiday season every year.  An annual even organized by the National Audubon Society (NAS), Buena Vista Audubon (BVAS) has been sponsoring the local CBC since the 1950s.

The Christmas Bird Count began in 1900 as an alternative to a holiday hunting contest.  Conservation was in its beginning stages, and there was concern about declining bird populations.  Members of the Audubon Society began a new holiday tradition, a "Christmas Bird Census," that would count birds during the holidays rather than hunt them.  Currently, there are over 2,500 individual CBCs conducted worldwide.

This "Community Science" has been vital over the years, with the data collected by observers allowing researchers, biologists, and wildlife agencies to study the long-term health of bird populations across North America. This helps create strategies to protect birds and their habitats, and helps identify key environmental issues and impacts, such as climate change.
