Audubon Great Backyard Bird Count (GBBC)
The Great Backyard Bird Count (GBBC) is a free, fun, and easy event. GBBC is a collaboration between the National Audubon Society and the Cornell Lab of Ornithology. Anyone can take part in the GBBC, from beginning bird watchers to experts. You can participate from your backyard, around your neighborhood, or a local park, anywhere in the world. Recently, more than 160,000 participants submitted their bird observations online, creating the largest instantaneous snapshot of global bird populations ever recorded.
How to participate in GBBC
- The 2023 GBBC will be held Friday-Monday, February 17-20, 2023
- Count for as little as 15 minutes in your own backyard (or longer if you wish) on one or more days of the four-day event.
- Report your sightings online at birdcount.org. Each checklist submitted during the GBBC helps researchers learn more about birds around us and how to the environment we share.
Audubon Christmas Bird Count (CBC)
Since the Christmas Bird Count (CBC) began over a century ago, the data collected has become one of only two large pools of information used by ornithologists and conservation biologists to find out how the birds of the Americas are faring over time. Anyone can participate in the Christmas Bird Count. However, there is a specific methodology you must follow.
How to participate in CBC
- CBC occurs between December 14 to January 5 every year. Local counts are scheduled for one day during this period.
