The Christmas Bird Count is the longest running citizen science wildlife census in the world. Administered by the National Audubon Society, the data collected by CBC participants for over a century is among the largest resources informing ornithologists and conservation biologists about how the birds of the Americas are faring over time.

Whether you are a relatively new birder or an expert, you can participate in Christmas Bird Counts and contribute important data – all you have to do is join a CBC circle near you! Participants follow specified routes through a designated 15-mile diameter circle, counting every bird they see or hear all day.

All CBCs are conducted from December 14 to January 5.
