The Christmas Bird Count: Over a Century of Community Science

By Regional Wildlife Biologist Susan Bard Each year, thousands of birders participate in what’s known as the Christmas Bird Count (CBC). This long-standing winter census is used for various purposes such as assessing the health and trends of bird populations, public education, as well as guiding organizations in their conservation efforts. The CBC originated in 1990 with the National Audubon Society, and today is an engaging, nationwide event. Data gathered from these surveys is used by many researchers, conservationists, and management agencies (including Maine Department of Inland Fisheries and Wildlife) to monitor spatial and temporal patterns of various bird species across the country. Additionally, when combined with surveys such as the Bird Atlases which the Department is currently updating (learn more at maine.gov/birdatlas), these data may aid in identifying, preserving, and enhancing key habitats, species needs, and addressing environmental issues. The CBC is a free program with participants covering a wide-range of backgrounds–from beginner birders to ornithologists. Over a 24-hr period, every bird seen or heard within an established 15-mile wide diameter circle is counted. Current and historical survey results are available online for specific counts or bird species. This year’s CBC runs from Dec 14, 2018–Jan 5, 2019. For those passionate about birds and interested in contributing to the CBC, you may find a local count here: https://www.audubon.org/conservation/join-christmas-bird-count. Not able to get involved this year? The Great Backyard Bird Count is a great alternative that occurs in February.
