Reaching heights of nearly three feet (one meter), the King Penguin is one of the largest penguins in the world, second only to the closely related emperor penguin. Their markings resemble those of the emperor penguin (black back with white front and orange and yellow on the head and neck), but the two species generally do not have overlapping distributions.

Emperor penguins spend all year in Antarctica, while king penguins live in sub-antarctic island groups and in southern South America. The king penguin is the largest penguin outside of Antarctica.

King penguins are foraging predators that feed primarily on fishes (but occasionally take squids) in shallow water near their nesting sites. Many predatory seabirds are known to take juvenile king penguins, while leopard sealskiller whales, and other large predators are the only species that typically eat adults. 

Though they feed in the marine environment, king penguins mate and nest on rocky shores during the southern hemisphere summer, when both male and female remain faithful to their partner for at least one nesting season. Approximately one third of all individuals remain faithful to the same partner for multiple years. Each parent participates in incubating a single egg, by taking turns resting the egg on its feet while the other parent feeds. After hatching, the parents continue to care for the juvenile for approximately one year. During this time, the juvenile is dependent on its parents for food, warmth, and protection from predators.

With apparently increasing populations, the king penguin has been determined to be a species that is not at risk of extinction. It is not dependent on ice for nesting (like Antarctic penguins) and it generally does not live in places with significant local human impacts (like South American or African penguins). And it does not rely on krill and other prey that are vulnerable to overfishing and climate change (like many other Southern Ocean predators). However, it is important to continue to study king penguins and monitor their populations to ensure that any future negative trends are discovered early and are handled accordingly.
