Puffins breed in burrows on sea cliffs and islands, facing welfare challenges from changing sandeel prey availability driven by climate-related sea temperature rise.
Puffin welfare is fundamentally linked to sandeel availability, which in turn depends on North Sea water temperature and productivity. Individual chicks that starve in burrows because parents cannot find sufficient sandeels experience prolonged starvation - one of the most significant welfare impacts in British seabird populations. Adult birds that make repeated unsuccessful foraging trips exhaust themselves in the attempt. The root cause - climate-driven warming of the North Sea - can only be addressed by climate action. In the shorter term, monitoring, marine protected area management around key foraging grounds, and fishing pressure reduction can support sandeel availability.
