African penguins face catastrophic population decline due to food shortages, oil spills and climate change. Individual and population welfare are deeply intertwined.
African penguin welfare operates at two levels. Individual penguins affected by oil spills experience acute suffering — coating by oil causes hypothermia, toxic ingestion and starvation. Rehabilitation is welfare-positive for individuals and contributes to population maintenance. At the population level, chronic food stress caused by industrial fishing competition and climate-driven fish stock shifts causes widespread hunger during the chick-rearing period, with chicks dying from starvation in otherwise suitable nesting habitat. Addressing population-level welfare requires fishery management reforms that create exclusion zones around colonies during breeding season — a policy intervention with clear welfare benefits.
