Wild Puffin Welfare: Ocean Warming and Breeding Stress

Atlantic and other puffin species face mounting welfare challenges as climate change warms seas, depletes prey fish, and disrupts ancestral nesting colonies. Understanding these threats is essential for effective conservation.

Key Facts

Atlantic puffins breed in large colonies on rocky islands, spending most of their lives at sea
Puffins can carry up to 10 small fish in their beaks at once to feed chicks
Warming ocean temperatures have shifted sand eel and herring distributions, a primary puffin prey base
Poor breeding seasons linked to food scarcity cause chick starvation and parent exhaustion
Puffin populations in some colonies have declined over 50% in recent decades
Puffins are highly site-faithful, returning to the same burrow each year for decades
Oil spills, plastic ingestion, and bycatch in fishing nets are significant mortality risks

Welfare Considerations

Puffins experience acute welfare stress during poor forage fish years when adults must fly longer distances to find food, often returning with insufficient catch for their single chick. Starving chicks suffer from cold and hunger in their burrows, while parents endure physical exhaustion from extended foraging trips. Plastic ingestion can cause internal injury and impaired digestion. Net entanglement leads to drowning — a particularly distressing death for birds adapted to breath-hold diving. Climate-driven shifts in prey availability represent a systemic welfare challenge that may affect millions of seabirds across the North Atlantic.

What You Can Do

Support seabird conservation organizations like Project Puffin and the RSPB
Reduce plastic waste that enters marine environments and harms seabirds
Advocate for policies that limit overfishing of forage fish like sand eels and herring
Choose sustainably sourced seafood certified by the Marine Stewardship Council
Learn about and share information on seabird monitoring programs that track colony health
