About the Event

The Great Backyard Bird Count (GBBC) is a fun, free, and easy event that engages bird watchers of all ages in counting birds to create a real-time snapshot of bird populations. 

Anyone can take part, from the young to the not so young, from beginning bird watchers to experts. And, you can participate from your backyard or anywhere in the world.

What You Need to Do

Participants are asked to count birds for as little as 15 minutes (or longer) on one or more days of the four-day event and report their sightings online at

You can count birds in as many places and on as many days as you like within the four days. Submit a separate checklist for each new day, for each new location, or for the same location if you counted at a different time of day. Estimate the number of individual species you saw during your count period.

Why GBBC Is Important

Bird populations are always shifting and changing. By participating in this event and submitting your bird observations, you'll be helping to provide vital, up-to-date information.

Each checklist submitted during the GBBC helps researchers at the Cornell Lab of Ornithology and the National Audubon Society learn more about how birds are doing, and how to protect them and the environment we share.
