Audubon Louisiana invites birdwatchers to participate in the longest-running citizen science survey, the annual Audubon Christmas Bird Count (CBC). From December 14 through January 5, birders and nature enthusiasts in Louisiana will take part in this tradition, many rising before dawn to participate.

“Louisiana is home to millions of birds each winter, including waterfowl, shorebirds, and songbirds. Understanding how the populations of these birds are changing is revealed through CBC efforts, which is critical for knowing how to best ensure their survival,” says Dr. Erik Johnson, Director of Bird Conservation for Audubon Louisiana.

Each year, the Audubon Christmas Bird Count mobilizes over 72,000 volunteer bird counters in more than 2,400 locations across the Western Hemisphere. The Audubon Christmas Bird Count utilizes the power of volunteers to track the health of bird populations at a scale that scientists could never accomplish alone. Data compiled in Louisiana will record every individual bird and bird species seen in a specified area, contributing to a vast citizen science network that continues a tradition stretching back more than 100 years.

To date over 200 peer-reviewed articles have resulted from analysis done with Christmas Bird Count data. Bird-related citizen science efforts are also critical to understanding how birds are responding to a changing climate. This documentation is what enabled Audubon scientists to discover that 314 species of North American birds are threatened by global warming as reported in Audubon’s groundbreaking Birds and Climate Change Study. The tradition of counting birds combined with modern technology and mapping is enabling researchers to make discoveries that were not possible in earlier decades.

In addition to counting up some of our more common birds, Louisiana CBC participants also look for vagrants – birds that normally spend the winter elsewhere, but made a wrong turn somewhere along the way. Last winter, Louisiana CBC volunteers found a total 254 species of birds, including amazing vagrants like Lucy’s Warbler, Ferrugineous Hawk, and Brown Boobies.

Birders of all ages are welcome to contribute to this fun, nationwide citizen science project, which provides ornithologists with a crucial snapshot of our native bird populations during the winter months. Each individual count is performed in a count circle with a diameter of 15 miles. At least ten volunteers, including a compiler to coordinate the process, count in each circle. The volunteers break up into small parties and follow assigned routes, counting every bird they see. In most count circles, some people also watch feeders instead of following routes.

The Audubon Christmas Bird Count began in 1900 when Dr. Frank Chapman, founder of Bird-Lore – which evolved into Audubon magazine – suggested an alternative to the holiday “side hunt,” in which teams competed to see who could shoot the most birds. 116 years of counting birds is a long time, but the program somehow brings out the best in people, and they stay involved for the long run. And so the tradition continues.

The Audubon Christmas Bird Count is a citizen science project organized by the National Audubon Society. There is no fee to participate and the quarterly report, American Birds, is available online. Counts are open to birders of all skill levels and Audubon’s free Bird Guide app makes it even easier to chip in. For more information and to find a count near you visit www.christmasbirdcount.org.
