Great Backyard Bird Count

gbbcThe Great Backyard Bird Count (GBBC) is joint project of the Cornell Lab of Ornithology and the National Audubon Society. The annual four-day eventengages bird watchers in counting birds. Participants count birds for a little as 15 minutes, or as long as they want during each day of the event. The counts are entered and tallied to create a real-time snapshot of where birds are in North America and Hawaii. This year marks the first international bird count and birds will be counted from all over the world.

Scientists can learn a lot from knowing where birds are. Bird populations are in constant flux. No single scientist or group of scientists could possibly collect and document the movements and distribution of the almost 1,000 bird species found across North America and Hawaii.

Data collected by the GBBC can be viewed by anyone with internet access. Participants can explore data from their home town, state, or the entire continent. They can compare data from the current year with those from past counts. They can view top ten lists of the most numerous birds, the most frequently reported birds, as well as which regions reported the most species.
