Researchers tracking lesser black-backed gulls near Dutch offshore wind farms discovered that fishing bycatch does not lure the birds into turbine zones, contrary to earlier assumptions.
Ecologist Rosemarie Kentie and colleagues at NIOZ monitored gulls from a colony on Neeltje Jans, an island off the Zeeland coast. The team had hypothesized that discarded fish from commercial vessels outside the wind farm might attract gulls into the turbine area, where collision risks escalate. The data contradicted this theory. Even on weekends, when fishing activity drops sharply, gulls rarely entered the wind farm.
The finding matters for understanding how seabirds interact with offshore renewable energy infrastructure. Wind farms pose collision hazards, but the mechanisms driving or preventing gull visitation remain incompletely understood. Most birds in the study avoided the turbines, though some males showed exceptions to this pattern. The research suggests that food availability from fishing operations is not the primary factor drawing these gulls toward operational wind farms.
Offshore wind expansion continues across Europe, raising questions about impacts on seabird populations. Lesser black-backed gulls, a species of conservation concern in some regions, face multiple threats from fishing pressure and coastal habitat loss. Understanding what attracts or repels them from wind farms helps inform mitigation strategies and placement decisions for future installations.
The study's limitation lies in its focus on a single colony. Gull behavior may vary across different populations, fishing intensities, and geographic regions. Kentie's work contributes to the growing body of research examining seabird-wind farm interactions, but broader geographic studies would strengthen conclusions about whether this pattern holds elsewhere in northern Europe's expanding offshore wind sector.
