King Penguins
|
Vital Statistics
Scientific name: Aptenodytes patagonicus
Height: 85-95 cm
Weight: 9 – 16 kg (varies throughout the breeding season)
Breeding age: ~6 years
Breeding frequency: A successful pair of king penguins is likely to breed two out of three years
Breeding season: Highly protracted, laying occurs any time from November to April, usually peaking in December
Age to fledging: ~ 310 days
Longevity: Probably 25+ years
Name Derivation: "Featherless diver from Patagonia" – being birds, penguins do have
feathers, of course!
Foraging Statistics
What do I eat? Ice fish (lots of it), and some squid.
What eats me? Orcas and perhaps leopard seals when at sea; eggs and chicks are eaten by skuas and giant petrels.
Range trip time: 3 days to 3 weeks depending on breeding stage.
Range trip length: varies with breeding stage from 600 - >2500 km.
Depth of water where foraging: 200 - 4000 m but in summer king penguins dive mainly to depths of around 50 - 120 m, and in winter to 150 - 240 m.
Extreme dive depth/time: 300 m / ~8 minutes.
Distribution & Abundance
Distribution: King penguins breed on most subantarctic islands in the Southern
Ocean, including South Georgia, Marion, Prince Edward, Crozet, Kerguelen, Heard,
Macquarie and the Falkland Islands.
Abundance: Very difficult to estimate population sizes at large colonies: South Georgia, Îles Crozet and Macquarie Islands have several hundred thousands pairs. Almost all breeding populations are increasing.
General Comments
Most Heard Island king penguins breed at the southeastern end of the island. The largest colony is at Doppler Hill, numbering more than 25,000 breeding pairs. A smaller colony is present at Spit Bay, with about 1500 pairs.
