GBBC 2026




The Great Backyard Bird Count (GBBC) is a free, fun, and easy event that engages bird watchers of all ages in counting birds to create a real-time snapshot of bird populations. Participants are asked to 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 their sightings online at birdcount.org. Anyone can take part in the Great Backyard Bird Count, from beginning bird watchers to experts, and you can participate from your backyard, or anywhere in the world.


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. Last year, more than 140,000 participants submitted their bird observations online, creating the largest instantaneous snapshot of global bird populations ever recorded.



The 29th annual GBBC will be held Friday, February 13 to Monday, February 16, 2026. Please visit the official website at www.birdcount.org for more information and be sure to check out the latest educational and promotional resources.

Tri-colored Blackbird
The Audubon mission is to conserve and restore natural ecosystems, focusing on birds, other wildlife, and their habitats for the benefit of humanity and the earth’s biological diversity. We are dedicated to the preservation of natural habitats and native species, and to educating and inspiring others to help protect those resource values.


We offer field trips in the local area and host monthly chapter meetings which always include a fascinating program on topics of interest about our local habitat, birds, and conservation. The public are invited to these free programs.
Event Calendar

We are active “Citizen Scientists”, participating in surveys contributing to raptor research, and maintaining an ongoing nest box program. Learn about the kind of conservation work we do and how you can get involved. We also manage two Christmas Bird Counts.
