As the holiday season draws to a close, an annual holiday tradition also is coming to a close – the National Audubon Society’s Christmas Bird Count (CBC). Since 1900, when 27 birders conducted 25 surveys and tallied 96 species, the CBC has grown in 2019 to 81,601 people who participated in surveys in 2646 count circles and tallied 672 species and nearly 43 million birds.
