Great Backyard Bird Count

Great Backyard Bird Count History

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.
