How to recognise it
King Penguins are striking birds with a distinctive black and white plumage, accented by vibrant orange-yellow patches on their head and neck. They have a sleek, streamlined body with flipper-like wings adapted for swimming.
Adults display a silvery-grey back, contrasting with their white belly. The orange ear patches and throat fade to pale yellow down the neck. Juveniles have a duller plumage, lacking the bright colours of adults.

Its song and calls
King Penguins are known for their loud, trumpet-like calls, which are essential for partner and chick recognition in crowded colonies. Their vocalisations include a variety of whistles, grunts, and squawks.
The most distinctive sound is a high-pitched 'mew' followed by a lower 'moo', often described as 'oui-oui'.

Tips for seeing it
- Look for King Penguins on subantarctic islands and beaches
- Observe from a distance to avoid disturbing breeding colonies
- Listen for their distinctive trumpet-like calls
- Visit during the breeding season (November to March) for the best viewing opportunities
What it eats
King Penguins primarily feed on small fish, particularly lanternfish, and squid. They are deep divers, capable of reaching depths of 360 meters to catch prey.
Their foraging trips can last several days and cover hundreds of kilometres from their breeding sites.
Nesting and breeding
King Penguins have a unique breeding cycle that spans 14-16 months. Pairs form long-term bonds and engage in elaborate courtship displays involving mutual preening and vocalisations.
Unlike most birds, King Penguins don't build nests. Instead, they incubate a single egg on their feet, covered by a fold of abdominal skin. The egg is pear-shaped to prevent rolling if dislodged.
Both parents take turns incubating the egg for about 55 days. After hatching, chicks are cared for in crèches while parents forage. Fledging occurs after 10-13 months, an exceptionally long period for birds.
Behaviour
King Penguins are excellent swimmers, using their powerful flippers to 'fly' underwater at speeds up to 12 km/h. On land, they walk upright with a characteristic waddle.
They are highly social, forming large colonies during the breeding season, where they engage in complex courtship displays and vocalisations.
Conservation
While currently listed as Least Concern, King Penguins face threats from climate change, which affects their food sources and breeding habitats. Ocean pollution and overfishing also pose risks.
Conservation efforts focus on protecting their breeding grounds and monitoring population trends.
