In October 2024, the African penguin turned the primary penguin species on this planet to be listed as critically endangered by the Worldwide Union for the Conservation of Nature.
This can be a unhappy report for Africa’s solely penguin, and means it’s now only one step away from extinction.

How did this occur? African penguins (Spheniscus demersus) are discovered solely in Namibia and South Africa. Their numbers have been declining for the reason that 1800s. At the moment, they have been burnt in ships’ boilers, their eggs have been harvested and consumed as a delicacy, and their nests have been destroyed by guano-harvesters in search of a wealthy supply of fertiliser.
Such actions are thankfully not allowed. African penguins have been protected below South Africa’s Sea Birds and Seals Safety Act since 1973 (and extra just lately below the Marine Threatened or Protected Species Laws since 2017).
These legal guidelines and rules ban the seize of penguins or their eggs, and any intentional hurt finished to them. Fertilisers not use guano (penguin excrement). After egg and guano harvesting stopped, the shortage of prey (small fish like sardines and anchovies) turned the principle situation for penguins from the early 2000s.
The impacts of local weather change on the distribution and abundance of their meals, and competitors with industrial fisheries, have contributed to a 70% discount on this penguin’s inhabitants between 2000 and 2024.
We’re a bunch of scientists from universities and non-governmental organisations which have, for years, centered on options to save lots of the African penguin. In the present day, except the South African authorities takes pressing steps to guard the African penguin, it is going to doubtless change into extinct within the wild by 2035. At current there are fewer than 20,000 birds left within the wild.
Penguins are just like the canaries within the coal mine. They’re disappearing as a result of the ecosystem they depend on, along with many different species, together with fish focused by business fisheries, is in dire straits. By saving them, we defend their ecosystem and the opposite species that depend on it.
Penguins are additionally invaluable to the financial system, bringing in income from tourism.
What’s labored for the penguin to date

The destruction of African penguins’ nesting habitat over the centuries has been partly repaired by organising synthetic nests in penguin colonies. New analysis has discovered that these enhance the variety of penguin eggs that hatch by 16.5% in comparison with pure floor or bush nests which stay weak to the weather.
Steps to guard the African penguins’ meals provide additionally labored. One step was the experimental “no-take zones”, the place the South African authorities prohibited fishing across the penguins’ breeding areas between 2008 and 2019.
The federal government closed business fishing of sardines and anchovies in a 20km radius round Robben Island on the west coast and St Croix Island in Algoa Bay for 3 years. Throughout this time, business fishing across the neighbouring penguin colonies of Dassen Island and Hen Island was nonetheless permitted. The closure was alternated each three years till 2019 to see if it affected the penguin populations.
The outcomes have been optimistic. Penguins have been capable of catch fish with much less effort and their chicks’ well being and survival charges improved. The inhabitants elevated by about 1% – a small improve, however essential, contemplating they have been already endangered.
In parallel, the African Penguin Biodiversity Administration Plan was printed in 2013. The plan centered on managing predators, reminiscent of Cape fur seals and kelp gulls, and rescuing deserted eggs and chicks. 1000’s of particular person penguins have been saved and launched into the wild through the years.
What has gone unsuitable for the penguin
Regardless of these efforts, the African penguin inhabitants fell quicker from the mid-2010s. This was largely as a result of sudden collapse of the colony at St Croix Island, then the world’s largest African penguin colony.
This collapse coincided with the institution of ship-to-ship bunkering actions (refuelling ships at sea somewhat than in ports) in Algoa Bay in 2016. Whereas the ships have been refuelling, 4 oil spills occurred.
Ship-to-ship bunkering additionally elevated underwater noise air pollution resulting from a ten-fold improve of maritime visitors within the bay.
Our earlier analysis has revealed that African penguins are extremely delicate to underwater noise. Noise from ships or drilling tools chases penguins away from their feeding grounds.
This additionally makes use of up the African penguins’ vitality, usually at a time after they have none to spare. Penguins want vitality reserves earlier than beginning their annual moult, after they keep ashore for 3 weeks with out consuming to interchange all their feathers. In the event that they don’t discover sufficient meals earlier than or after that irritating interval, they die.
Can the African penguin be saved?
The experimental use of no-take zones in penguin breeding areas resulted in 2019. A panel of worldwide specialists was then appointed by the South African authorities to evaluation the experiment and recommend a method ahead.
The panel stated no-take zones must be put in place round all colonies. They really helpful methods to steadiness the profit to penguins towards the fee to fisheries.
However the authorities departed from the panel’s suggestions and put in place fishing closures geared toward minimising financial losses to fisheries, and never conserving penguins. For instance, they closed down fishing in some areas the place penguins don’t hunt for fish.
In March 2024, the non-profit organisation BirdLife South Africa and the South African Basis for the Conservation of Coastal Birds, represented by the Biodiversity Legislation Centre, requested the Pretoria excessive courtroom to evaluation and put aside the Minister of Fisheries, Forestry and Setting’s August 2023 choice on fishing closures round key African penguin breeding colonies. The case continues to be underway.
In the meantime, bunkering in Algoa Bay has stopped quickly after the South African Income Service detained 5 ships in September 2023 on allegations of breaching customs legal guidelines.
Subsequently, small will increase within the St Croix Island penguin inhabitants have been seen for the primary time in almost ten years.
African penguins can bounce again when environmental circumstances are good. Authorities and non-governmental organisations have labored laborious to stop numerous threats to penguins. However essential work stays to be finished to guard their foraging habitat (the ocean round their colonies) from polluting actions.
Penguins additionally want safety from competitors with industrial fisheries for fish provides.
