What is the Christmas Bird Count? The Christmas Bird Count (CBC) is a long-standing program of the National Audubon Society, with over 100 years of community science involvement. It is an early-winter bird census, where thousands of volunteers across the U.S., Canada, and many countries in the Western Hemisphere go out over a 24-hour period on one calendar day to count birds.
Audubon’s 121st Christmas Bird Count will be conducted between the dates of Monday, December 14, 2020 through Tuesday, January 5, 2021. The Christmas Bird Count occurs December 14 to January 5 every year.
