Scattered across California are 145 Important Bird Areas that provide more than 10 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.
Audubon California has used the best science to identify and map these Important Bird Areas. Part of an international effort, these sites were nominated by local experts and selected according to strict criteria:
Support over 1% of the global or 10% of the state population of one or more sensitive species
Support more than nine sensitive bird species
10,000 or more observable shorebirds in one day
5,000 or more observable waterfowl in one day
