Each year the Audubon Society hosts a three-week bird count across the United States and Canada.
The Audubon Christmas Bird Count mobilizes over 72,000 volunteer bird counters in more than 2,500 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 locally will record every 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.
Over 300 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 respond to a changing climate. This documentation 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 enables researchers to make discoveries that were not possible in earlier decades.
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 winter. Each 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 loop. The volunteers break up into small parties and follow assigned routes, which change little from year to year, counting every bird they see. Some people watch feeders, while others count in defined circles and paths.
