From Dec. 14 through the first week of January, families, scientists, students and bird enthusiasts of all ages and abilities across the United States will take part in one of the best forms of citizen science: Christmas Bird Counts. During CBCs, small groups span out in a designated area to identify and count all birds encountered. Information gathered is submitted to the National Audubon Society, where the data is compiled and available to scientists.CBCs are a great opportunity to get outside to look at birds during a season not normally considered for outdoor time.
