The Golden Gate Raptor Observatory (GGRO) uses long-term volunteer-powered research programs to track the fall migration of raptors through the Marin Headlands.

 GGRO Raptor Migration Interns split their time evenly between the banding and hawkwatch programs, and work with a large and dedicated group of volunteer community scientists on a daily basis.

When banded hawks subsequently encountered by humans are—hopefully—reported to the US Bird Banding Laboratory, the GGRO receives a report of where the bird was found and what the circumstances were.

The Golden Gate Raptor Observatory coordinates volunteer scientists to monitor and track the autumn raptor migration over the Marin Headlands.

To date, the Golden Gate Raptor Observatory (GGRO) has published 26 articles in peer-reviewed scientific journals, contributed to Master's and PhD candidates' research, and given more than 100 presentations at national and international conferences.
