Golden Gate Raptor Observatory
Our Work
The Golden Gate Raptor Observatory coordinates volunteer scientists to monitor and track the autumn raptor migration over the Marin Headlands.
Our Work
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.
Our Work
Visit this page during the fall migration season (mid-August to early-December) for daily count totals.
Our Work
Volunteer radiotrackers fit a banded hawk with a radio transmitter weighing less than 3 percent of body weight, and follow the hawk constantly as it moves through California.
Our Work
Specially trained volunteers sit in small blinds in the hills of the Headlands, trapping and banding raptors and taking measurements and health data.
Our Work
The Golden Gate Raptor Observatory (GGRO) uses long-term volunteer-powered research programs to track the fall migration of raptors through the Marin Headlands.
Our Work
During the autumn months, our teams of volunteer hawk counters identify and tally 19 species of birds of prey, working under the leadership of an experienced dayleader.
Our Work
Raptor tracking provides a more complete picture of raptor movements between banding and recovery
