Audubon Christmas Bird Count

Citizen Science Program
Audubon Bird Count – Debra Moss

The 120th Annual Audubon Christmas Bird Count takes place in December 14, 2019 - January 5, 2020. It is the longest running Citizen Science survey in the world and provides critical population data. Data from over 2,300 circles are entered after the official count and become available under the Data & Research link. Please click here for locations and to sign-up for the 118th Christmas Bird Count.

How does participation work?

There is a specific methodology to the CBC, and you must make arrangements to participate in advance with the circle compiler, but anyone can participate.

Each count takes place in an established 15-mile wide diameter circle, and is organized by a count compiler.

If your home is within the boundaries of a CBC circle, then you can stay at home and report the birds that visit your feeder on count day as long as you have made prior arrangement with the count compiler. Check out the sign-up link above for information on how to contact the compiler.

Since it is free, how is this program funded?

The Christmas Bird Count now relies 100% on donations to provide support to compilers and volunteers on count day, to manage the historic database, and to fund the technology to make historic data available to researchers. Until recently there was a $5.00 participation fee which annually funded this hemisphere-wide program.

The data collected by CBC participants over the past century and more have become one of only two large pools of information informing ornithologists and conservation biologists how the birds of the Americas are faring over time.

In 2012 CBC participation was made FREE to make it accessible to anyone. Now we ask for your support to keep the program free and to help us ensure the future of the program. Please make a donation today to this very important citizen science effort.

How To Participate
