King penguin
The king penguin (Aptenodytes patagonicus) is the second largest species of penguin, smaller than but somewhat similar in appearance to the emperor penguin.
King penguins mainly eat lanternfish, squid, and krill. On foraging trips, king penguins repeatedly dive to over 100 metres (300 ft), and have been recorded at depths greater than 300 metres (1,000 ft). Predators of the king penguin include giant petrels, skuas, the snowy sheathbill, the leopard seal, and the orca.
The king penguin breeds on the subantarctic islands at the northern reaches of Antarctica, South Georgia, southern Argentina, and other temperate islands of the region. It also lives on Macquarie Island in the Southern Ocean and the Falkland Islands.
This bird was exploited commercially in the past for its blubber, oil, meat, and feathers. Today it is fully protected.
In 1778, the English illustrator John Frederick Miller included a hand-coloured engraving of the king penguin in his Icones animalium et plantarum. He coined the binomial name Aptenodytes patagonica and specified the type locality as the Mari antarctico, the Antarctic Ocean. The locality was restricted to South Georgia by Gregory Mathews in 1911.
The International Ornithologists' Union considers the species monotypic, recognizing no subspecies. However, some taxonomic authorities recognize two subspecies, A. p. patagonicus and A. p. halli; in this system, patagonicus is found in the South Atlantic and halli in the South Indian Ocean (at the Kerguelen Islands, Crozet Island, Prince Edward Islands, and Heard Island and McDonald Islands) and at Macquarie Island.
The king penguin stands at 70 to 100 cm (28 to 39 in) tall and weighs from 9.3 to 18 kg (21 to 40 lb). Although female and male king penguins look alike, they can be separated by their calls. Males are also slightly larger than females. The mean body mass of adults from Marion Island was 12.4 kg (27 lb) for 70 males and 11.1 kg (24 lb) for 71 females. Another study from Marion Island found that the mean mass of 33 adults feeding chicks was 13.1 kg (29 lb). The king penguin is approximately 25% shorter and weighs around a third less than the emperor penguin.
At first glance, the king penguin appears similar to the larger, closely related emperor penguin, with a broad cheek patch contrasting with surrounding dark feathers and yellow-orange plumage at the top of the chest. However, the cheek patch of the adult king penguin is a solid bright orange whereas that of the emperor penguin is yellow and white, and the upper chest tends to be more orange and less yellowish in the king species. Both have colourful markings along the side of their lower mandible, but these tend towards pink in emperor penguin and orange in king penguin.
