What is special about Galapagos penguins?

Animal records of the Galapagos penguins

The northernmost penguins in the world!

Galapagos penguins live in the northern hemisphere, with the northernmost colony even living north of the equator. When searching for food, Galapagos penguins regularly cross the equator and are the only penguin species in the world that even occasionally breed north of the equator – an absolutely unique phenomenon in the penguin kingdom and proof of their incredible adaptability.

The second smallest penguin in the world!

With a size of only around 50 centimeters and a weight of about 2 kilograms, the Galapagos penguins are the second smallest penguins in the world. Only the little penguin (Eudyptula minor) is smaller, measuring 30 to 40 centimeters and weighing approximately 1,5 kilograms. By comparison, the largest penguin in the world is the emperor penguin, measuring over one meter and weighing more than 40 kilograms.

The rarest penguins in the world!

They are endemic to Galapagos and critically endangered. With only approximately 1200 to 2000 individuals remaining, the Galapagos penguin unfortunately holds the sad record of being the rarest penguin species. Because they depend so heavily on cool ocean currents, their numbers also fluctuate dramatically due to El Niño events, which bring warm water and massively reduce their food sources.

Galapagos penguins have developed remarkable cooling strategies: They pant like dogs, hold their flippers away from their bodies, and channel blood to the unfeathered skin around the eyes and base of their beaks to release heat. They also seek shelter in shady lava caves and spend considerable time in the cool waters of the Humboldt Current.

The Galapagos Penguin: Exciting Facts About Unique Birds

Habitat and distribution of the Galapagos penguin

The Galapagos penguin () is a fascinating example of endemism, as it is found exclusively in the Galapagos archipelago. Its habitat is remarkable, characterized by the volcanic nature and the islands' unique ocean currents.

• Geographical uniqueness: It is the only penguin that lives permanently on the equator and even regularly ventures into the northern hemisphere in search of food – an absolute exception.
• Island focus and currents: Over 95% of the population is concentrated on the western islands of Fernandina and Isabela. This is because the cool, nutrient-rich Cromwell Current meets the warmer surface current here, creating rich fishing grounds critical for survival.
• Volcanic habitat: Instead of breeding on ice or sandy beaches, Galapagos penguins take advantage of the rugged volcanic coastlines. Consequently, they find shelter in lava tubes, crevices, and caves from the intense equatorial sun and some terrestrial predators.

Reproduction and breeding behavior of the Galapagos penguin

The breeding behavior of these unique penguins is flexible and highly dependent on unpredictable environmental conditions, especially water temperature and food availability.

• Pair bonding: Galapagos penguins form monogamous pairs that often stay together for several broods and recognize and bond through calls and mutual feather preening.
• Opportunistic breeders: Galapagos penguins do not have a fixed annual breeding season like their Antarctic relatives. Instead, they breed opportunistically, often twice a year, when cool, nutrient-rich waters rise to the surface due to upwelling, thus providing ample food. This often correlates with cooler La Niña periods.
• Nesting in lava caves: They lay their one or two eggs in protected caves or deep crevices in the rugged volcanic lava rocks, often near the waterline. These locations not only offer protection from the heat but also a certain degree of security from egg thieves. Galapagos penguins use the same nest repeatedly for several years.
• Parental care: Both parents incubate the eggs for about 38-40 days and take turns feeding the chicks.
• Chick mortality: Due to the often scarce food supply, the parents must often concentrate their limited resources on the stronger offspring. For this reason, often only one chick survives per brood.

Facts about Galapagos penguin chicks

Raising the young presents special challenges for the parents in this unusual, warm penguin habitat.

• Feeding: Both parents take turns hunting small fish and feeding the chick with pre-digested food directly at the safety of the nest.
• Protection from heat and cold: Newly hatched chicks with their thin down coats not only need to be warmed by their parents, but also, and above all, protected and shaded from the strong equatorial sun.
• No group supervision: Unlike many other penguin species, Galapagos penguins do not form large groups of chicks (nurseries). Instead, the young remain at or near the nest until they are ready to fledge.
• Hazards: In addition to the risk of starvation due to a lack of food, the chicks are particularly vulnerable to introduced predators such as cats, dogs, and rats. Galapagos buzzards and short-eared owls also occasionally hunt penguins.
• Becoming independent: After about 60-65 days, the moulting into juvenile plumage takes place, after which the young penguins venture into the sea on their own for the first time to learn to hunt.

Diet and hunting technique of the Galapagos penguin

The Galapagos penguin (Spheniscus mendiculus) is a fantastic hunter but a poor diver, whose survival depends on cool ocean currents and whose body exhibits incredible adaptations to heat.

• Food: Their main diet consists of small schooling fish such as sardines, anchovies, and mullet, which are found in the cool upwelling areas. They also occasionally eat crustaceans.
• Good hunters: Galapagos penguins mostly hunt during the day and relatively close to the coast. They are excellent swimmers and herd schools of fish together into bays or dive beneath them, forcing the fish to the surface to catch them.
• Bad divers: Galapagos penguins are less skilled at diving than most other penguin species: While they can dive to depths of up to 15 meters, this is relatively shallow compared to the king penguin, which regularly dives to depths of over 100 meters. Furthermore, they can only hold their breath for about 90 seconds.

The Galapagos penguin struggles with food shortages during so-called El Niño events. Starvation and breeding failure can cause the population to plummet by more than two-thirds.

population and protection status

How rare are Galapagos penguins?

According to the IUCN Red List, the Galapagos penguin (Spheniscus mendiculus) is currently classified as "Endangered." The smallest member of the African penguin family is fighting a dramatic battle for survival. It is not only one of the most endangered penguin species in the world, but is also the rarest penguin species of all.

How many Galapagos penguins are left?

With only approximately 1.200 to 2.000 adult individuals, the population is alarmingly small. Furthermore, the population trend continues to decline (IUCN 2020). The population can collapse dramatically, particularly during El Niño events.

What dangers threaten the Galapagos penguin?

• Main threat El Niño (ENSO): By far the greatest threat is posed by strong El Niño events. The associated warming of the ocean water suppresses the upwelling of cool, nutrient-rich water, causing fish stocks to collapse. This leads to mass starvation and complete failure of penguin breeding. After catastrophic El Niños, the population can plummet by more than two-thirds. Global climate change could increase the frequency and intensity of strong El Niño events in the future, which would further exacerbate the situation.
• Danger from introduced species: Introduced species such as cats, dogs and rats on some islands pose an immense threat to eggs, chicks and even adult penguins.
• Danger from bird flu: Avian influenza was first detected on the Galapagos Islands in 2023. Such new pathogens could pose a massive threat to the already weakened population.
• Other threats: Marine pollution, death as bycatch in fishing nets, disturbance by tourists;
• Conservation measures in the Galapagos National Park: Strict monitoring of the penguin population, control of invasive species, regulation of fishing and tourism, research into diseases and feeding ecology. However, long-term success remains closely linked to global climate conditions.

Watching Galapagos penguins: Experience penguins at the equator

Observing the unique Galapagos penguin (Spheniscus mendiculus) in its natural habitat is undoubtedly the ultimate highlight for any Galapagos visitor. These small penguins can be spotted resting on the black lava rocks or swimming in the turquoise waters.

Because they are critically endangered, responsible tourism is crucial: Always observe these cute birds from a distance. If the animals are very curious and approach you, stay calm and let the penguin decide how close it wants to get. No matter how close an animal comes to you, you should never try to touch it.

The sight of a penguin basking in the equatorial sun or skillfully darting through tropical waters is an unforgettable testament to the amazing adaptability of nature in the Galapagos.

Where can you see Galapagos penguins?

Exclusively on the Galapagos, of course. However, they aren't found on all islands there either: The best chances to observe this rare penguin species are on the western islands of the Galapagos archipelago, where cool, nutrient-rich currents dominate.

Galapagos penguins are most often spotted from the dinghy of small cruise ships or while snorkeling or diving near the coast. However, extremely respectful treatment of the penguins is vital for the survival of this species!

Penguin watching by Magazine.Travel

We discovered Galapagos penguins on the Galapagos Islands of Fernandina, Isabela, and Bartolomé. We were able to observe them several times on land, in water, and even underwater (while hunting). Our penguin photos, which are used in the Galapagos Penguin Profile and the Animal Encyclopedia, were taken on these occasions. All of our photos show the penguins in the wild.

Can you swim with Galapagos penguins?

The penguins must not be harassed or disturbed under any circumstances! They are very curious, and sometimes a penguin will swim right up to you. In this case, it's best to stay still, observe the animal quietly, and simply enjoy the closeness. One particularly curious penguin even bit our camera. In other words: Yes, it is possible to swim with the penguins, but only if they want to.

In summary, the small, endemic Galapagos penguin (Spheniscus mendiculus) is best observed on the western islands, such as Isabela and Fernandina, as well as on Bartolomé. Its agility in the water makes encounters while snorkeling or from boats a fascinating experience.
