Since the Christmas Bird Count began over a century ago, it has relied on the dedication and commitment of volunteer citizen scientists. In other words, it all starts with you!

The Christmas Bird Count season is December 14 through January 5 each year. Your local count will occur on one day between those inclusive dates. If you have more than one local count, they will probably be conducted on different dates within the CBC season. You can pick the most convenient date, or participate in more than one count.

There is a specific methodology to the CBC, but everyone can participate. The count takes place within "Count Circles," which focus on specific geographical areas. Each circle is led by a Count Compiler. Therefore, if you are a beginning birder, you will be able to join a group that includes at least one experienced birdwatcher. In addition, if your home is within the boundaries of a Count Circle, then you can stay home and report the birds that visit your feeder or join a group of birdwatchers in the field. In either case, if you have never been on a CBC before your first step is to locate and contact your local Count Compiler to find out how you can volunteer.
