Wild penguin populations face multiple threats to welfare and survival from climate change to pollution.
Wild penguin welfare is threatened by a convergence of climate-related stressors. Warming seas reduce prey availability — krill and small fish — causing chick starvation and adult physiological stress. Climate change is also disrupting rainfall patterns, with increased rain events flooding penguin burrows and killing chicks through hypothermia. Oil spills from tanker traffic near southern African breeding colonies cause mass mortality events with significant welfare harm. Conservation programs including oil spill response, supplemental feeding during extreme events, and fishing exclusion zones directly improve penguin welfare.
