“Magellanic penguins are fast swimmers reaching speeds of 15 mph or more.”

Magellanic penguins live on both the Pacific and Atlantic coasts of South America. They are carnivorous, flightless, seabirds with a diet of small fish and crustaceans. Named for the controversial Portuguese explorer, Ferdinand Magellan, this penguin species sports a unique, all-black coat of feathers on its back – with white on its belly. The black coat makes them extremely difficult to spot from the air while their white belly is camouflaged from below by light from the sky. This evolutionary gift helps the bird to evade predators while they navigate and feed in the dark oceans. They are highly social animals that mate for life and live in groups that include as many as 400,000 penguins.

Scientific Name and Types

The scientific name of the Magellanic penguin is Spheniscus magellanicus. Magellanicus refers to the explorer Ferdinand Magellan. He took note of these penguins as he sailed near South America in 1520. Magellanic penguins belong to the Spheniscidae family and are in the class Aves. There are no subspecies.


Fossil records indicate that the common ancestor of all penguins lived as long as 40 million years ago and was around five feet tall. They are believed to have originated in Antarctica, which was covered in forests at the time and connected to what would become New Zealand, Australis, South America, and surrounding islands. These ancient ancestors of penguins had diverged from the ancestors of petrels and albatrosses around 71 million years ago.

The arrival of the ice age 35 million years ago brought brutal changes to the ancient ancestors of the penguin. The continents of Australia and South America drifted away from Antarctica while ocean currents encircled it. This cooling climate likely killed the older penguins – leaving them to compete with whales for the same prey.

While most of the ancient penguins became extinct, others, like the Magellanic penguin, swam to warmer waters to found new lineages. Some species, like the emperor penguin, stayed in Antarctica and evolved adaptations to living in the cold environment.

Appearance and Behavior

As mentioned earlier, Magellanic penguins have black feathers on their backs, heads, and wings. They have white feathers on their underside and two black stripes across the top of their chest. This coloration provides camouflage against predators. The Magellanic penguin can be distinguished from their close relative, the endangered African penguin which has only one black stripe on its chest. Magellanic penguins also have a ring of white running from their chin up to above their eyes.

Magellanic penguins are the largest member of the genus Spheniscus. The height range for these birds is 24 to 30 inches with a weight of 5 to 14 pounds. Males are usually larger than females. For perspective, a Magellanic penguin that’s 30 inches tall is equal in height to 2 bowling pins stacked up to make a tower. A 10-pound penguin is equal in weight to an average size housecat.

The flippers of a Magellanic penguin as well as its slick feathers help it to swim through the water at high speed with a maximum of 15 mph. This level of speed helps them capture prey including fish and some crustaceans.

Penguins absorb a lot of salt water as they swim through the ocean. Fortunately, they have special glands located near their eyes that release salt, so they don’t have too much in their bodies.

When a Magellanic penguin gets overheated, it sheds some of its feathers to cool its body temperature. They have also been known to hold their wings out at their sides to increase air circulation. Sometimes this penguin will pant like a dog to cool off!

If humans approach a group of Magellanic penguins, these birds quickly seek shelter in their burrows. Plus, the fact that a group of penguins can number as high as 400,000 gives these birds protection from predators. There is safety in numbers!

A Magellanic penguin’s colors help to protect it from predators while keeping them hidden from prey. A penguin’s white underside keeps them hidden from fish and other prey that cannot see them against the light filtering in from above. In addition, the black feathers on their back keep them hidden from some predators as they blend in with the dark waters of the ocean. This color combination is called countershading.

This penguin is definitely a social animal living with hundreds of thousands of other penguins in groups called colonies. Though these birds shy from humans when they come near, they are aggressive with each other. In fact, they are known to be one of the most aggressive penguins out of the many species.

When breeding season begins, male penguins that have just reached sexual maturity, fight with other males causing great injury. Biting, flapping wings, and loud calls are all a part of this competition. Female Magellanic penguins fight one another over males as well.

Magellanic penguins on both the Pacific and Atlantic shores of the tip of South America. Specifically, on the coasts of Chile and Argentina as well as on the Falkland Islands. Unlike their arctic cousins, these penguins have adapted to live in a dry, temperate climate.

This species of penguin spends most of its time in the ocean waters off of South America – usually about 150 feet from shore. During the breeding season, from September to Mid-April, their habitat becomes the grassy shores of the beaches where they construct burrows or make their nests under shrubs and bushes.

After the breeding season has ended, Magellanic penguins migrate north along the South American coast to the more seasonable climates of Peru or Brazil. Thousands of Magellanic penguins can be seen swimming toward their winter post during this migration – which can involve a lengthy journey of up to 4,000 miles. Perhaps the sight of thousands of penguins swimming together is what caught the attention of Magellan and his crew!


What Do Penguins Eat
Penguins primarily eat fish, with other seafood like crustaceans and krill added to the mix.

What do Magellanic penguins eat? These birds are carnivores that eat krill, cuttlefish, squid, anchovies, and sardines.

One of the most interesting facts about these particular penguins is that they dive from 100 to 200 feet into the ocean to hunt for food. Group foraging is a common practice of Magellanic penguins. Large groups of them dive together to hunt for prey and are able to capture more fish than just one penguin hunting solo.

Predators and Threats

Leopard seals, killer whales, and large fur seals are all predators of adult Magellanic penguins. They are captured by these predators while swimming in the ocean.

Chicks and eggs of Magellanic penguins have several predators. They’re eaten by seagulls, rats, foxes, and sometimes feral cats while still on shore.

Some other threats to these penguins include the loss of their food source. Commercial fishermen are capturing a lot of the same fish that these penguins eat. Competing with the commercial fishing industry for food has endangered the future of many types of penguins. Water pollution such as oil spills presents an environmental threat to Magellanic penguins. Flooding on these shores also puts penguin chicks and eggs in danger.

The official conservation status of these penguins is Near Threatened with a decreasing population.

Reproduction, Babies, and Lifespan

Like most penguins, Magellanics are monogamous. They return to the same mate every breeding season beginning in September. How can a female find her mate in a colony of hundreds of thousands of noisy, braying penguins? With keen hearing and an exceptional memory, a female penguin is able to recognize her mate through his unique call.

Hopefully, the male penguin has already scouted out their nesting site and constructed a burrow for shelter. Around October, the female penguin lays 2 eggs. The eggs have a 40-day incubation period. During that time, the male and female share the task of caring for the eggs. When one is watching over the eggs, the other bird is out in the ocean hunting for food.

The baby penguins are called chicks. They are born weighing just a few ounces and are about 3 inches long. They are covered in grayish-blue downy feathers and don’t begin to grow any waterproof feathers until they are almost one month old. These little chicks are totally dependent on their parents. The burrow serves as warm shelter and protection for penguin chicks with a light layer of feathers.

Penguin chicks are totally reliant on their doting parents.


Penguin chicks eat the prey brought to them by their parents. One of the parents eats the prey, then regurgitates it into a chick’s mouth so the baby can digest it. As a chick grows older, it’s able to eat small pieces of torn-up fish and other prey.

Penguin chicks leave the nest when they have fledged. Fledging is when a chick grows a full collection of feathers that it will have as an adult. Penguin chicks usually leave the nest at around 4 months old.

The lifespan of a Magellanic penguin is 25 to 30 years. The record for the oldest Magellanic penguin is 36 years old.

According to the IUCN Red List of Threatened Species, the estimated population of Magellanic penguins is 1.1 to 1.6 million pairs.

• 900,000 on the coast of Argentina
• 100,000 on the Falkland Islands
• Between 144,000 to 500,000 pairs in Chile

The conservation status of Magellanic penguins is Near Threatened and its population is decreasing.

About the Author

After a career of working to provide opportunities for local communities to experience and create art, I am enjoying having time to write about two of my favorite things - nature and animals. Half of my life is spent outdoors, usually with my husband and sweet little fourteen year old dog. We love to take walks by the lake and take photos of the animals we meet including: otters, ospreys, Canadian geese, ducks and nesting bald eagles. I also enjoy reading, discovering books to add to my library, collecting and playing vinyl, and listening to my son's music.
