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.
We invite you to participate! Simply tally the numbers and kinds of birds you see for at least 15 minutes on one or more days of the count, February 12-15, 2016. You can count from any location, anywhere in the world!
If you’re new to the count, first register online then enter your checklist. If you have already participated in another Cornell Lab citizen-science project, you can use your existing login.
In 2015, Great Backyard Bird Count participants in more than 100 countries counted 5,090 species of birds on more than 147,000 checklists! See the full 2015 summary.
