For over 25 years, the Golden Gate Raptor Observatory (GGRO) has been a program of the Golden Gate National Parks Conservancy in cooperation with the National Park Service.
The GGRO’s mission is to inspire the preservation of California raptor populations. The GGRO was formed in the early 1980s to track the Golden Gate migration, an annual flight of tens of thousands of hawks, eagles, falcons, and vultures, birds collectively called “raptors.”
New from GGRO
Fifty years ago, biologists gathered a convening with an unprecedented specific purpose—saving a species on the brink, the Peregrine Falcon. Learn about that pivotal event and how you can support the GGRO’s hosting of an important raptor conference this fall, which continues to draw inspiration from the ’65 meeting. more >>
What’s the greatest number of raptor (bird of prey) species seen in one day on Hawk Hill? And what’s the highest volume of raptors spotted in a day? Read on to find out—and learn how you can witness a possible “best day” at the West Coast’s premier hawk migration monitoring spot. more >>
Golden Gate Raptor Observatory Programs
The GGRO’s reason for being is to conduct long-term studies of the seasonal movements of birds of prey along the Pacific Coast, particularly over the Marin Headlands, to further the understanding and preservation of raptor populations.
As a part of our dedication to conservation, we are committed to public education. Our volunteers learn much about raptor ecology as they are trained to be citizen scientists for our projects. We also use Hawk Hill in the Marin Headlands as a living classroom for children and adults alike. Our educational programs have reached many thousands of people over the past 25 years.Donate to the GGRO's DAP Fund >>
