The Great Backyard Bird Count

Join the fun! Join The Great Backyard Bird Count!

Launched in 1998 by the Cornell Lab of Ornithology and National Audubon Society, The Great Backyard Bird Count (GBBC) is a free, fun, and easy event that takes place each year in February and engages bird watchers of all ages. It's a great chance to enjoy birds and nature! To participate, all you need to do is count birds for as little as 15 minutes (or as long as they wish) on one or more days of the four-day event and report your sightings online at gbbc.birdcount.org.

Anyone can take part in the GBBC, from beginning bird watchers to experts, and you can participate from your backyard or anywhere in the world.

More than 160,000 people of all ages and walks of life worldwide join the GBBC each year to create an annual snapshot of the distribution and abundance of birds. The results are reported online to Cornell University’s Laboratory of Ornithology and aid research on where bird species are spending the winter.

To learn more and view past GBBC results, visit gbbc.birdcount.org.

The 2018 GBBC will be held Friday, February 16, through Monday, February 19, 2018. If you would like to participate in a guided Audubon GBBC event, check out the events below taking place at our Centers.
