Your Membership & Donations Matters

We do not require people to be members to participate in most of our programs. We pride ourselves for operating on an "open source" model.

We offer a variety of resources and learning opportunities completely free of charge — the newsletter, our website, most of our field trips, our monthly speaker series, the annual Christmas Bird Count, and many other community activities. But we depend on your voluntary contributions to do this work. Through your membership dues and charitable gifts, you make our programs possible. Together, we connect to many others who care deeply about our mission, learn how to best protect avian biodiversity, and become strong advocates for conservation.
