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. It’s free, fun, and easy—and it helps the birds. See and use the 2007 GBBC PowerPoint presentation.

Participants count birds anywhere for as little or as long as they wish during the four-day period. They tally the highest number of birds of each species seen together at any one time. To report their counts, they fill out an online checklist at the Great Backyard Bird Count web site.

As the count progresses, anyone with Internet access can explore what is being reported from their own towns or anywhere in the United States and Canada. They can also see how this year's numbers compare with those from previous years. Participants may also send in photographs of the birds they see. A selection of images is posted in the online photo gallery.

In 2006, participants reported a record-breaking 7.5 million birds of 623 species. They submitted 60,616 checklists, just 433 shy of an all-time record for total checklists.
