About Great Backyard Bird Count

Launched in 1998 by the Cornell Lab of Ornithology and National Audubon Society, the Great Backyard Bird Count was the first online citizen-science project to collect data on wild birds and to display results in near real-time.

Since then, more than 100,000 people of all ages and walks of life have joined the four-day count each February to create an annual snapshot of the distribution and abundance of birds.
