Join other birders from around the state in the 119th Audubon Christmas Bird Count during the holiday season. In most areas, the typical one-day counts start in mid-December and continue into early January. Experienced and novice birders are invited. This is a nationwide, citizen science project proud to celebrate 119 years.
A map view of the areas expected to be included in the 119th CBC can be found below. If you’re interested in participating next season, check out the map to find a count near you; more circles will be added as they are approved. Green and yellow circles are open for new participants, and red circles are full.
There is a specific methodology to the CBC, and all participants must make arrangements to participate in advance with the circle compiler within an established circle, but anyone can participate.
Each count takes place in an established 15-mile wide diameter circle, and is organized by a count compiler. Count volunteers follow specified routes through a designated 15-mile (24-km) diameter circle, counting every bird they see or hear all day. It’s not just a species tally—all birds are counted all day, giving an indication of the total number of birds in the circle that day.
If you are a beginning birder, you will be able to join a group that includes at least one experienced birdwatcher.
