The North Bay Heron and Egret Project is a collaborative effort between Audubon Canyon Ranch (ACR) and the San Francisco Bay Bird Observatory (SFBBO) to monitor colonially nesting herons and egrets in the San Francisco Estuary. It is the result of ACR's continuing commitment toward the protection of nesting herons and egrets in our region and is a source of information for scientists and researchers, land developers, planning agencies, birding enthusiasts and local residents.
The locations of heronries monitored by Audubon Canyon Ranch and San Francisco Bay Bird Observatory can now be viewed using Google Earth. To take a virtual tour, download the file and open it with Google Earth (scroll down here for more directions).
If you choose to visit a heronry in person, please use caution. Birds are especially vulnerable to disturbance during the nesting season (approximately February-June). During this time, please take care not to walk near or under the heronries, and always respect private property.
