The Great Backyard Bird Count (GBBC) is an annual four-day event in which bird watchers of all ages throughout North America count birds and report their counts 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.
