Atlantic puffin (Fratercula arctica) colonies are experiencing breeding failure linked to climate-driven shifts in sand eel availability, creating significant welfare and conservation challenges.
Puffin welfare impacts from food shortage are significant: starving chicks experience prolonged hunger before fledging underweight or dying in the burrow; adults attempting to raise chicks in poor food years expend enormous energy with low success rates. Chronically unsuccessful breeding seasons cause accumulated energetic stress in adult birds. Climate change welfare impacts cannot be addressed at the individual bird level — mitigation requires systemic responses including greenhouse gas emissions reduction and sand eel fishery management. Sustainable fisheries management of Ammodytes stocks in UK waters provides the most direct near-term benefit to puffin welfare. The UK has introduced sand eel fishing bans in certain areas which represent welfare as well as conservation interventions.
