GGRO Volunteers in Action Gallery
The Golden Gate Raptor Observatory's (GGRO) 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.”
