Welcome to Marin Audubon Society

For more than 60 years Marin Audubon has worked to protect wildlife habitat in Marin, sometimes stepping in to buy land that is slated for development.

MAS also 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 Rail, and the annual Christmas Bird Counts. For a listing of many of our activities and events please check our Calendar.
