Alaska Seabird Population Study Highlights Breeding Success Amidst Declining Numbers

A recent research initiative in Homer, Alaska, has provided new insights into the reproductive dynamics of Black-legged kittiwakes (*Rissa tridactyla*), revealing a nuanced picture where overall population numbers are declining while breeding productivity remains stable. The study, conducted by Galen June, a 2025 Hollings scholar studying marine biology with a minor in statistics at Old Dominion University, focused on monitoring colonies at Gull Island and within Homer harbor. June spent the summer of 2026 at the Kachemak Bay National Estuarine Research Reserve (NERR), mentored by Ingrid Harrald. The research methodology involved weekly counts of breeding attempts from boats at Gull Island, which is owned by the Seldovia Native Association and restricted to boat access. Additionally, productivity was monitored from the Pioneer Dock in Homer harbor, allowing researchers to observe nests closely and collect data on egg laying, chick hatching, and fledging. The findings indicate that while the total population of kittiwakes was down compared to previous years, the productivity rate—the success of eggs hatching and chicks fledging—remained similar to historical averages. This suggests that while fewer birds are attempting to breed, those that do are successfully raising their young. Beyond the data collection, the research experience included exploration of the broader Alaskan environment. June documented 15,392 images of wildlife during the summer, capturing scenes from locations including Kenai Fjords National Park and Denali National Park. The project underscores the ongoing efforts to understand marine ecosystem health through direct observation and statistical analysis. The study was conducted under the Hollings Scholarship program, managed by the Office of Education at NOAA. **References** 1. NOAA Office of Education.
