The National Audubon Society invites birdwatchers to participate in the longest-running community science survey, the annual Audubon Christmas Bird Count (CBC). On Friday, December 17, birders and nature enthusiasts around the Eagle Valley will take part in this tradition, hosted by Walking Mountains Science Center. 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 our count will record every individual bird and bird species seen in two geographic circles around Eagle and Dotsero, contributing to a vast community science network that continues a tradition stretching back 122 years.

The 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 skill levels 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. The volunteers break up into small parties and follow assigned routes, counting every bird they see.

We will meet at the Brush Creek Greenhouse in Eagle and groups will drive to their assigned routes in either the Eagle or Dotsero circles. We will reconvene in the afternoon to compile data. Warm drinks and snacks will be provided!
