Atlantic puffins face food shortages driven by climate change affecting sand eel prey availability. Colony declines reflect welfare deterioration at population scale.
Puffin welfare deterioration from climate-driven prey shifts is a slow-motion welfare crisis invisible to most observers. Chicks starving in burrows while parents range further for prey represents genuine suffering at scale. The connection between individual puffin welfare and systemic climate drivers means that addressing puffin welfare requires macro-level climate action alongside local management.
