The Christmas Bird Count (CBC) is an annual, citizen-science bird census organized by the National Audubon Society that takes place between December 14 and January 5. Volunteers count all the birds they can find and hear within a specific 15-mile diameter circle on one day, with the data used to monitor bird populations, understand their health, and guide conservation efforts. It is the longest-running citizen science survey in the world, with origins dating back to 1900.
If you have never participated in one before, this may be the year to give it a try. Contact the compiler of a location near you to see if they are taking new observers, in the field or at a feeder.
