King Penguin | Facts, Habitat and Where to See Them in the Wild

King Penguin 

Aptenodytes patagonicus

The second-largest penguin species, known for their striking orange ear patches and upright regal stance, looks dressed ready for a formal occasion. They breed in huge numbers on sub-Antarctic islands, and have the longest, most complex breeding cycle of any penguin. A visit to a king penguin colony is like a party to the senses, the cacophony of vocalisations, the sea of penguins waddling purposefully, and the stark smell of guano in the air. This is one of the most sought-after wildlife encounters on a penguin expedition cruise.

There have been a few observations of king penguins showing up far beyond their usual range, such as in New Zealand. The most recent record was in April 2025 when a king penguin appeared on Pipikaretu Beach along the Otago Peninsula. 

King Penguin Cruises & Expeditions

The most immersive way to encounter these remarkable birds is on expedition cruises to see king penguins, particularly in the wildlife-rich islands of South Georgia. Unlike traditional voyages, small ship Antarctic cruises are designed for exploration—allowing you to reach remote beaches where vast king penguin colonies gather in their hundreds of thousands. With expert guides leading each landing, you gain deeper insight into their behavior, breeding cycles, and the fragile ecosystems they inhabit.

A South Georgia penguin expedition offers a level of access and intimacy that larger ships simply can’t match. With fewer guests on board, you’ll spend more time ashore, experience flexible itineraries, and enjoy close—but respectful—wildlife encounters. From stepping onto penguin-filled beaches to observing their interactions just meters away, these expeditions bring you face-to-face with one of the most extraordinary spectacles in the natural world.

King penguin breeding season in South Georgia

King penguins are residents of South Georgia year-round. Their extended breeding cycle means there is always endless activity to observe in the dense colonies.

The best time to see king penguins is during the austral summer from November to March; with peak activity and incredible photo opportunities in December and January.

Diet and Feeding Habits

King penguins are deep divers, often hunting in the open ocean, sometimes hundreds of kilometres from shore. The king penguin's diet varies seasonally and by location, they consume squid, crustaceans and small fish, but their favoured prey source is the bioluminescent lanternfish. 

They are highly efficient, streamlined swimmers, often capturing their prey by ‘pursuit deep diving’, a foraging strategy that involves actively pursuing prey at considerable depths. 

A study using time depth recorders revealed that king penguin diving trends correlate with the diel vertical migration of their primary prey, lanternfish. Lanternfish make daily migrations within the water column, ascending toward the surface at night and descending to the ocean depths during the day. The data showed that king penguins adjust their foraging patterns accordingly, diving to depths of over 350 meters during daylight hours, and remaining within 30 meters of the surface at night. 

King penguin predators on land & sea

King penguins face a range of predators when at sea and on land.

Depending on location, southern elephant seals can be potentially dangerous to king penguins. These are the largest seals on the planet, and although they are not looking to prey on the penguins, they pose a threat by accidentally squashing the penguins under their sheer size and motion as they gallumph through the breeding colonies.

Conservation Status

The International Union for Conservation of Nature (IUCN) currently classifies the king penguin as Least Concern. The total population of king penguins is thought to be roughly 2.23 million breeding pairs. 

Although the population trend appears to be increasing, the species remains highly vulnerable to climate change, particularly rising ocean temperatures that disrupt prey availability. In some regions, warmer waters have forced adult penguins to forage farther from breeding colonies, leaving chicks unattended for longer periods, leading to higher chick mortality.

Other threats include the occasional entanglement in discarded fishing nets and exposure to oil spills. While there are currently no recorded instances of king penguins caught as bycatch, they may still be susceptible. Notably, Fourteen of the eighteen penguin species have already fallen victim to bycatch. 

Fun Facts

• King penguins are the second largest penguin species, surpassed only by the emperor penguin.

• Early explorers mistook the fluffy brown chicks of king penguins for an entirely different species, nicknaming them 'woolly penguins'.

• King penguins are impressive swimmers, reaching speeds of up to 7.6 mph (12kph) underwater. 

• King penguins produce a unique two-voiced call using their syrinx, allowing them to produce two distinct frequencies simultaneously. This remarkable vocalisation helps parents and chicks recognise each other amid the bustling colonies.

• The king penguin’s lower mandible is a vibrant orange with UV-reflective properties, which play a key role in attracting mates and social signalling within the colony.

• King penguins have a nictitating membrane, a third transparent eyelid that acts like built-in googles, protecting their eyes underwater and from debris.

• A recent study revealed that a king penguin reached an impressive depth of 424.5 meters, setting a new record for the deepest dive ever recorded for this species.
