Welcome to Marin Audubon Society
The Marin Audubon Society was established in 1956 as part of the effort to prevent development of houses on Richardson Bay tidelands. MAS provides its members and the public many opportunities to experience the birdlife and nature of Marin County and beyond through Field Trips and Events, our monthly MAS newsletter The Clapper Rail, and the annual Christmas Bird Counts. For a listing of many of our activities and events please check our Calendar.
