Penguin of the week: King
August 17, 2007The King Penguin (Aptenodytes patagonicus) is the second largest species of penguin at about 90 cm (3 ft) tall and weighing 11 to 16 kg (24 to 35 lb), second only to the Emperor Penguin. There are two subspecies - A. p. patagonicus and A. p. halli; patagonicus is found in the South Atlantic and halli elsewhere.
King penguins eat small fish, mainly lanternfish, and squid and rely less than most Southern Ocean predators on krill and other crustaceans. On foraging trips they repeatedly dive to over 100 metres (350 feet), often over 200 metres (700 feet). This is far deeper than other penguins, other than their closest relative, the larger Emperor penguin.
King Penguins breed on the subantarctic islands at the northern reaches of Antarctica, as well as Tierra del Fuego, the Falkland Islands, and other temperate islands of the region. The total population is estimated to be 2.23 million pairs and is increasing.
The male king penguin incubates the egg much as male Emperor penguins, but the King penguins do this during the warmer summer season, when food is more available. Once the egg is laid, the male will care for it. The female goes to the open sea and will return in about 21 days to take her turn keeping the egg warm. The male will only go about 1 month without food. The chick hatches in about 54 days. The chick is cared for by both parents for 30 to 40 days. At this time it joins a crèche for warmth and protection from predators.
