Description

The nation's longest-running community science bird project fuels Audubon's work throughout the year. 2025 will be the 125th year of the CBC! Now a long-standing program of the National Audubon Society, with over 120 years of community science involvement, it is an early-winter bird census, where thousands of volunteers across the U.S., Canada (where Audubon partners with Birds Canada), and many countries in the Western Hemisphere go out over a 24-hour period on one calendar day to count birds.
