Recently, a scientific study revealed that more than 60,000 African penguins died of starvation between 2004 and 2011 following the collapse of sardine stocks, which are a primary food source for the species. This finding highlights the severe impact of marine ecosystem changes on seabird populations.
About African Penguin
The African penguin (Spheniscus demersus) is a flightless marine bird species endemic to the southern African region. It is well adapted to life in the ocean and spends most of its time at sea, coming ashore mainly for breeding, moulting, and resting.
Habitat and Distribution
African penguins are typically found within 40 kilometres of the coastline. They inhabit the Atlantic coast of southern Africa, with their range extending along the coasts of Namibia and South Africa. Coastal islands and mainland shores serve as important breeding and moulting sites.
Physical Characteristics
-
The species is easily identified by a black stripe and distinctive black spots on its chest, which are unique to each individual, similar to fingerprints.
-
It has pink glands above the eyes, which become brighter pink as temperatures rise, helping regulate body heat.
-
African penguins are flightless, with flippers adapted for efficient swimming.
Breeding and Moulting Behaviour
African penguins traditionally breed in burrows dug into guano, which provides insulation against extreme heat and protection from predators.
During the annual moulting period of about 21 days, penguins:
-
Come ashore,
-
Shed and regrow their feathers, and
-
Cannot enter the water to feed, often losing up to half of their body mass during this time.
Lifespan
The average lifespan of an African penguin in the wild is around 20 years, although survival rates have declined sharply in recent decades.
Threats to Survival
African penguins face multiple threats, including:
-
Collapse of fish stocks, especially sardines, due to overfishing and ecosystem changes,
-
Global warming–induced shifts in marine and atmospheric conditions,
-
Habitat degradation and reduced food availability near breeding colonies.
These pressures have led to mass starvation events and declining reproductive success.
Conservation Status
According to the International Union for Conservation of Nature (IUCN), the African penguin is classified as Critically Endangered, indicating an extremely high risk of extinction in the wild.
