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.
We also publish two annual reports, the Season Summary and the Pacific Raptor.
