Atlantic Puffin Welfare: Seabird Conservation and Forage Fish Decline

Atlantic puffins face serious welfare threats from climate-driven forage fish collapse, plastic ingestion, and bycatch mortality. Conservation requires protecting their food supply and breeding colonies.

Key Facts

Atlantic puffins (Fratercula arctica) are declining in parts of their range due to reduced availability of sand eels and other forage fish caused by ocean warming
Puffins feed chicks primarily on sand eels, sprats, and herrings — when these collapse, chick starvation is widespread and measurable
Bycatch in gill nets and long-lines kills tens of thousands of puffins annually across the North Atlantic
Puffins nest in burrows on remote islands and are highly vulnerable to introduced predators such as rats and mink
Plastic debris ingestion has been documented in puffins, causing gut impaction and exposure to toxic chemicals
Colony monitoring on islands like Skomer (UK) and Seal Island (Maine) shows that breeding success correlates tightly with forage fish availability in the surrounding sea
Climate change is shifting the timing of forage fish peaks, creating mismatches with puffin chick-rearing demand (phenological mismatch)

Welfare Considerations

Puffin chick starvation events are among the most visible welfare consequences of ocean ecosystem disruption. When parent birds cannot find adequate forage fish within reasonable foraging range, chicks slowly weaken and die in their burrows — a prolonged, distressing process. Adult puffins also face energetic depletion during failed breeding seasons. Bycatch drowning is another major welfare concern: entangled birds experience struggling and asphyxiation. Rat predation on eggs and chicks adds a significant mortality burden on island colonies. Addressing puffin welfare requires ecosystem-level action on fisheries management and climate mitigation, not just direct protection of individual birds.

What You Can Do

Support marine protected areas that safeguard forage fish spawning grounds around puffin colonies
Back fisheries reform policies that set sustainable catch limits for sand eels and other small pelagic fish
Donate to seabird conservation organisations such as the RSPB, Audubon Society, and Project Puffin
Reduce plastic waste to lower ocean plastic pollution affecting seabirds
Support rat eradication programmes on puffin nesting islands, which dramatically improve breeding success
Choose sustainably certified seafood that does not deplete the forage fish puffins depend on
Advocate for climate action as warming oceans are the root driver of forage fish range shifts
