Puffins face a changing ocean as climate alters fish distribution. Understanding these welfare impacts informs conservation priorities.
Puffin chicks that starve because parents cannot find adequate sand eel prey experience prolonged suffering before death. Adults making lengthening foraging trips expend increasing energy with reduced success. Climate-driven welfare harm to seabirds requires both direct conservation action (reducing fishing pressure on prey species) and broader climate action to stabilize ocean temperatures.
