African Penguins Struggle to Survive Amid Growing Challenges

The African penguin, once a common sight along the southern African coastline, is now facing what conservationists increasingly describe as a fight for survival. Endemic to the waters of South Africa and Namibia, this iconic seabird has suffered a catastrophic population collapse over the past century. While historical threats such as egg harvesting and oil spills and more recently bunkering in Algoa Bay are well documented, a new and complex combination of pressures is now accelerating the species’ decline at an alarming rate.
The 2025 value of fewer than 8 750 breeding pairs reflects the most current consensus from conservation bodies and government reporting. The shortage of pilchards (sardines) along the South African coast and the resulting starvation of penguins are primarily caused by overfishing and climate change. These two factors work in tandem to deplete the penguins' primary food source and push the remaining fish away from their breeding colonies.
The Factors Influencing the Starvation of the African Penguins
Overfishing: Commercial fishing fleets extensively harvest sardines and anchovies, which constitute the primary diet of African penguins. Years of intense exploitation have significantly depleted fish stocks, causing a collapse in sardine biomass in critical areas off South Africa's west coast. This situation results in direct competition between the fishing industry and penguins for the same food resources.
Climate Change: Increasing sea temperatures and changing ocean conditions, such as temperature and salinity, are affecting the distribution and spawning success of sardine populations. These fish are migrating to cooler waters, often shifting from the west coast to the south coast, far from established penguin breeding colonies on islands like Robben and Dassen.
Ecological Traps: These environmental changes create an "ecological trap" for penguins, which return to their traditional breeding grounds based on historical cues, only to find inadequate food supplies for themselves and their chicks. During the breeding season, penguins have a limited foraging range, typically no more than 40 km from the nest. If the fish are too distant, adults cannot return in time, leading to widespread starvation among chicks and adults.
Vulnerability During Moulting: African penguins undergo an annual three-week moulting period during which they cannot enter the water to hunt and must rely solely on fat reserves. Food scarcity before or after this period means many birds lack the necessary reserves to survive the fast, resulting in high mortality rates.
Sewage leakage: Sardine populations in South Africa's coastal cities are impacted by the ecological issue of sewage leakage from major cities, including Cape Town and Gqeberha. This leakage acts as a stress enhancer, damaging the coastal marine ecosystems vital for sardines, especially during their early developmental stages. Chronic sewage leakage weakens sardine populations, hindering their recovery from overfishing and climate-related stress.
Ecosystem Imbalance
As ecosystems experience destabilisation, African penguins encounter increased predation pressure. Cape fur seals, which compete with penguins for food, also prey on them in certain regions. The decline in fish stocks exacerbates this conflict, resulting in an environment where penguins find it challenging to compete or evade predators.
Ineffective decision-making and management by the South African Government
Simon’s Town is at the heart of South Africa’s African penguin conservation crisis, as the Boulders and Stony Point colonies face steep declines due to food scarcity. Almost two years ago, the South African Navy conducted underwater explosions close to the penguin colonies, exacerbating the situation. Barbara Creecy, the former Minister of Forestry, Fisheries and the Environment, was criticised for delayed and inadequate action despite scientific evidence and legal pressure from conservation groups like SANCCOB and BirdLife South Africa. Economic concerns often limited temporary fishing closures around colonies. Only after extended legal battles did the government implement restricted fishing exclusion zones. Now, the African penguin is critically endangered, with Simon’s Town exemplifying how slow policy responses and competing interests can drive a species to the brink of extinction.
More recently former environmental minister Dr Dion George was criticised for failing to take decisive action to halt ship-to-ship bunkering in Algoa Bay, despite repeated warnings from scientists, conservation organisations, and civil society. The activity posed significant risks to marine biodiversity, including whales, seabirds, and sensitive coastal ecosystems, through the threat of oil spills, noise pollution, and intensified vessel traffic. Critics argue that Dr George’s inaction reflected a preference for commercial and shipping interests over environmental protection, leaving Algoa Bay vulnerable to avoidable and potentially irreversible ecological damage.
What Can Be Done to Save the African Penguin?
Urgent and coordinated action is essential to protect African penguins. Key measures include enforcing no-fishing zones around breeding colonies, stricter regulation of bunkering and shipping activities, and meaningful reductions in carbon emissions to combat climate change. Conservation organisations have shown that targeted interventions can be effective, but time is running out. The future of the African penguin hinges on whether government, industries, and consumers can prioritise ecosystem health over short-term economic gain.
A Symbol of a Failing Ocean
The African penguin is more than a beloved coastal icon. Its decline is a warning signal, highlighting the broader collapse of marine ecosystems under human pressure. Saving this species would represent a powerful commitment to restoring balance in our oceans. Failing to do so would mark the loss of Africa’s only penguin species, and a profound failure of environmental stewardship.
Conclusion
The starvation of African Penguins has led to a dramatic decline in the local penguin population, which is now classified as critically endangered. Conservation initiatives, such as the recent creation of no-fishing zones near important colonies, are being put into place to aid the species' recovery. If executed correctly, these measures could be beneficial, but experts caution that sustained, long-term efforts are essential to avert their extinction.
