Christmas Bird Count – Portland Area

Join the Christmas Bird Count (CBC) for a fun day identifying and counting birds seen in designated 15-mile diameter circles. This long-standing program of the National Audubon Society is lending important insight into the health and status of bird populations across North America.

Begun in 1900 as an alternative to the traditional hunts of anything that flew during Christmas Day, hundreds of Christmas Bird Counts are now conducted throughout the Western Hemisphere, and they continue to contribute valuable scientific data to the longest existing records of bird population trends. An amazing bibliography of Christmas Bird Count research and the entire historical record can be found here. The Portland CBC has been conducted since 1926 and is informing Portland Audubon’s urban conservation efforts.

Partners: National Audubon Society
