Participating is easy, fun to do alone, or with others, and can be done anywhere you find birds.

Choose the easiest way for you to share your birds:

All you need is a free Cornell Lab account to participate. This account is shared with Merlin, eBird, Project FeederWatch and other projects at the Cornell Lab of Ornithology. If you already have an account please use the same username and password for submitting your bird list for the Great Backyard Bird Count.

We recommend observing birds for at least fifteen minutes. See this page for more counting instructions.

It’s That Easy!
Submit one or more lists over the four days of counting and you become a contributing citizen scientist (community scientist). All eBird entries and saved Merlin Bird IDs over the four days contribute to the Great Backyard Bird Count.

“The kids love learning how to use binoculars, seeing beautiful birds up close, the excitement of the count, and contributing to something big. There are always some that don’t want to stop when it’s time to move to another activity!”

— Mark Fallon, Senior Naturalist at Briar Bush Nature Center
