YAAS field trip went well today, we had at least 16 people attend. Weather was nice, clear skies with a little fog early, not too cold early and warming up nicely by late morning. The species total of 44 is a good number for this early in the year. Thanks to all participants for a great day! -Mark Donahue

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.
