African penguins have declined by over 70% since 2000, facing threats from commercial fishing, oil spills, climate change, and nest site competition that have significant welfare implications.
African penguin welfare is compromised across multiple life stages. Adults forced to travel longer distances to find prey expend more energy and return less food to chicks, causing slow starvation of nestlings when prey is scarce. Oil spill events cause acute suffering for oiled birds that is highly visible and emotionally compelling, driving large-scale rehabilitation efforts. Less visible is the chronic nutritional stress experienced by adults and chicks when anchovy and sardine schools are depleted by commercial fishing around colony sites. South Africa closed a fishing exclusion zone around key colonies in 2011, but this has not reversed population trends, and advocates argue for larger exclusion areas.
