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."

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.


eBird Record all the birds you see, from anywhere in the world, at any time. Keep track of your own sightings and explore what others are seeing with interactive maps.
