For over 30 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.”

Make a gift to the GGRO today and do your part to keep Bay Area raptors flying. Your support allows us to keep a pulse on raptor population changes, monitor thier health, and track their movements throughout the Pacific Region.

The GGRO’s Data Anaylsis and Publication (DAP) Fund was started in 2004 to turn our hawk observations, banding data, radio-tracking, and satellite-tracking into widely seen scientific results. To date we’ve published more than 24 scientific articles and given over 100 conference presentations. Help us show the powerful impact that community science can have on wildlife conservation.
