Napa-Solano Audubon (NSAS) has two types of members: National members & Friends members. Those of you who pay your dues to National Audubon Society automatically become members of NSAS, receiving both the Audubon magazine and our local newsletter, the Song Sparrow. You are also welcome to participate in most of the NSAS activities. However, National Audubon sends the local chapters only a very minimal portion of your dues.

In order to provide support for our local education, conservation and science projects, we have created a Friends of NSAS membership category. These members receive all of the same benefits as National members but do not receive the Audubon magazine. Additionally, they are invited to special events and field trips open only to Friends, and receive discounts on books & other items. Friends memberships run July through June of each year, and ALL of these funds are used for local projects!
