This year, the Audubon Christmas Bird Count will mobilize nearly 80,000 volunteer bird counters in more than 2,600 locations across the United States, Canada, the Caribbean and Latin America. 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 [your town] will record every individual bird and bird species seen in a specified area, contributing to a vast community science network that continues a tradition stretching back to 1900.
“The Christmas Bird Count is a great tradition and opportunity for everyone to be a part of 123 years of ongoing community science,” said Geoff LeBaron, Audubon’s Christmas Bird Count director, who first started leading the community science effort in 1987. “Adding your observations to twelve decades of data helps scientists and conservationists discover trends that make our work more impactful. Participating in the Christmas Bird Count is a fun and meaningful way to spend a winter for anyone and everyone.”
When combined with other surveys such as the Breeding Bird Survey, Audubon’s Christmas Bird Count provides a picture of how the continent’s bird populations have changed in time and space over the past hundred years. The long-term perspective is vital for conservationists. It informs strategies to protect birds and their habitat, and helps identify environmental issues with implications for people as well. Christmas Bird Count data have been used in more than 300 peer-reviewed articles.
Birders of all ages and abilities are welcome to contribute to this fun, nationwide community 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, which change little from year to year, counting every bird they see. In most count circles, some people also watch feeders instead of following routes.
