Atlantic puffins face dramatic colony declines driven by climate-driven prey fish shortages, threatening seabird welfare across the North Atlantic.
Starvation is the primary welfare crisis for puffin chicks when parents cannot find adequate prey fish within foraging range. Adult birds undertaking exhausting extended foraging trips face energy depletion, while chicks left unfed for days experience acute hunger stress. Burrow flooding from increased rainfall, predation pressure from great skuas, and plastic ingestion add further welfare burdens to already struggling populations.
