Wild Gannet Welfare and Seabird Conservation

Northern gannets are spectacular seabirds whose welfare is linked to prey fish availability and colony disturbance from tourism and fishing impacts.

Key Facts

Britain holds 60% of the global northern gannet population, making UK waters critically important.
Bass Rock in the Firth of Forth is the world's largest gannet colony with over 75,000 pairs.
Gannets travel up to 500 km from colonies to find prey, primarily herring, mackerel, and sand eels.
Entanglement in nesting material (particularly nylon fishing line) causes injuries and death.
Climate change is shifting prey distributions northward, increasing average foraging distances.

Welfare Considerations

Gannet welfare is threatened at multiple life stages. Chicks need consistent provisioning from both parents — food shortages caused by prey scarcity force adults to abandon chicks. Adults entangled in nylon monofilament fishing line during nesting suffer injuries to legs, wings, and bills that impair feeding and ultimately cause death. Visitor disturbance at colonies causes nest abandonment and exposes eggs and chicks to weather and predation. The connection between marine food web health and gannet welfare is direct and measurable — seabirds serve as indicators of ocean ecosystem health. Protecting gannets requires both colony management and sustainable fishing policy.

What You Can Do

Visit gannet colonies only with appropriate wildlife operators who maintain safe observation distances.
Report entangled gannets to British Divers Marine Life Rescue (BDMLR) or RSPCA.
Participate in beach cleans to reduce the nylon fishing line that gannets incorporate into nests.
Support sustainable fishing policies that protect herring and mackerel stocks as gannet prey.
