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 on one day, or you can count for as long as you like each day of the event. It's free, fun, and easy-and it helps the birds."

Project FeederWatch is for everyone with a bird feeder. FeederWatchers count the birds that visit their feeders from November through March. They also learn more about birds and bird behavior and share their observations with researchers.

NestWatch provides a window into the private lives of birds. All you do is monitor any active nest during the spring and summer and collect information such as how many eggs are laid, when they hatch, and when the young birds take flight. NestWatch is free and and your observations help scientists learn how birds are responding to global climate change.
