Key places for California birds

With its dramatic coastlines, ocean environments, lush forests, blooming valleys, and vivid deserts, California’s spectacular natural landscapes host the largest, most diverse concentration of birds in the United States. Scattered across this geography are 177 marine and land-based Important Bird Areas that provide more than 19 million acres of essential habitat for breeding, wintering, and migrating birds. We must protect these sites to ensure the survival of our state’s rich array of birds.
To learn more about Important Bird Areas in California, explore our interactive map. This section of our website contains links to maps, site descriptions, and other information related to California’s Important Bird Areas. We encourage you to look around and learn more.
Audubon California has used the best science to identify and map these Important Bird Areas. Part of a national and international effort, land-based sites were nominated by local experts and selected according to strict criteria:
To nominate a new Important Bird Area, please email us with a brief description of your proposed site and location (click on the map above to determine if the area is already an IBA). A site will need to meet at least one of the criteria above and have data from within the past 10 years and for more than 1 year. If your site fits this description, we will send you a nomination form and instructions.
Thank you in advance for your help in monitoring California’s birds!
