COMMUNITY SCIENCE INDIVIDUALS COLLECT PEAK RAPTOR MIGRATION DATA DURING A PAUSE IN PROGRAMS.

During an unprecedented pause in programs at the Golden Gate Raptor Observatory (GGRO) from September 5 to October 14, 2024, hawkwatch teams unofficially continued collecting raptor migration data from Hawk Hill in the Marin Headlands of the San Francisco Bay Area. The pause in programming occurred during peak fall migration of raptors through the Pacific Flyway (mid-September through the beginning to mid-October). Hawkwatch volunteers (and banders), some with decades of training and experience at GGRO, met daily on their regularly scheduled team’s volunteer day, between September 6 and October 13, 2024, to collect hawkwatch data (sightings of raptors (species/age/sex) and environmental data such as wind speed and direction). Hawkwatch protocols practiced by the program were followed with minor alterations, apart from recording data using paper data sheets, which was previously used by GGRO before switching more recently to data-collection application software. More than 4,000 raptors counted, up to 19 species of raptors, raptors per hour rate, as well as photos of raptors taken during the paused period will be presented here. These observations and data collected vastly expand our knowledge and understanding of trends during peak raptor migration and contribute to 40 years of the program’s effort in raptor research.
