The Great Backyard Bird Count is an annual four-day event that engages bird watchers of all ages in counting birds to create a real-time snapshot of where the birds are across the continent. Anyone can participate, from beginning bird watchers to experts. It takes as little as 15 minutes. It’s free, fun, and easy—and it helps the birds.
The GBBC is jointly sponsored by the Cornell Lab of Ornithology and Audubon and is held every winter. You can learn more about the GBBC, learn about common winter birds, find out how kids can participate, view bird photos from GBBC participants, and much more at the Great Backyard Bird Count Web site.
