In other words, they have only a thin covering of down and are entirely dependent on their parents for food and warmth.
The young chick is brooded in what is called the guard phase , spending its time balanced on its parents' feet and sheltered by its pouch. During this time, the parents alternate every days, one incubating while the other forages.
Other varieties of penguins also practice this method of communal care for offspring. By April the chicks are almost fully grown, but lose weight by fasting over the winter months, gaining it again during spring in September. King Penguins form huge breeding colonies - for example the colony on South Georgia Island at Salisbury Plain holds over 25, birds and the one at St. Andrew's Bay over , birds.
Because of the long breeding cycle, colonies are continuously occupied. The King Penguin feeds its chicks by eating a fish, digesting it slightly and regurgitating the food into the chick's mouth. Because of their large size, King Penguin chicks take months before they are ready to go to sea. This is markedly different from smaller penguins, who rear their chicks through a single summer when food is plentiful. King Penguins time their mating so the chicks will develop over the harshest season for fishing.
In this way, by the time the young penguins are finally mature enough to leave their parents, it is summer when food is plentiful and conditions are more favorable for the young to survive alone.

Coloring Feathers : The upper parts are steel blue-grey, darkening to black on the head, sharply delineated from the pale underparts; the belly is white colouring to orange on the upper breast with bright orange ear patches. An immature bird will have yellow- rather than orange-tinged markings, and grey tips to its black brown feathers.
The chick is first covered with brown-grey down, before moulting into a thick, woolly brown coat borne until around 10—12 months of age. Their mandibular plates are black until the moult into immature plumage The 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.

King penguins breed yearly on the flat shorelines of the sub-Antarctic islands. Their cycle beings with a 1-month molting stage for both parents, which is complete by the end of October.
Once the molt is complete, the courtship stage can last for just over a month. The female lays a single, greenish-white egg in November or December. After laying the egg, the female leaves to feed and replenish the weight that was lost.
When the female returns, the partners take turns in incubating the egg, with shifts ranging from 5 to 22 days. The average birth mass for king penguin chicks is g. Post-hatching, the parents continue taking turns to incubate and feed the chick until May, when it is big enough to survive on its own. By May, the chicks are fairly independent.
They stay with the colony and survive off their stored fat until the following October. In these months, both parents leave to forage and return periodically to feed their chick.
Birth to independence takes 14 to 16 months. Juvenile king penguins do not reach reproductive maturity until 3 to 5 years of age. Successful parents do not begin their next breeding cycle until their chick has successfully fledged. This causes a successful breeding pair to begin the next season late. The outcome is usually a failed cycle because an egg laid after December typically is not successful.
However, this failure allows them to breed earlier the following season. The earlier that the breeding cycle begins the more likely it is to be successful.
This biennial pattern to their breeding cycle makes king penguin reproduction unique. Not all breeding pairs in a colony are on the same biennial cycle, and not all are guaranteed to follow the success-fail-success-fail pattern. It is most likely for them to follow this pattern or a success-fail-fail-success pattern. Some are on alternating cycles so that there are chicks born during every breeding season. It is believed that food availability plays a role in the timing and success rate of the breeding cycle because it directly affects the health of the parent.
Aubin and Jouventin, ; Bried, et al. King penguin parents highly invest in their reproductive cycles. The males must begin the cycle with enough fat stored to sustain them through courtship, egg-laying and the first part of incubation. By the end of their first incubation shift the males have typically lost 30 percent of their body weight. A minimum body mass of 10 kg is considered to be a critical mass for male king penguins.
When they are approaching 10 kg, the males must choose whether to abandon the egg or to continue waiting for the female to return and relieve them. Hatchlings are semi-altricial, and therefore have considerable development to achieve post-hatching. This requires a large parental investment to brood and nourish the young. Olsson, ; Olsson, Aptenodytes patagonicus has been generically documented as a long-lived bird.
However, no numerical lifespan data has been published. Captive king penguins can live up to 26 years. Flower, King penguins are one of only two penguin species that do not build nests. Instead of building a nest, king penguins carry their eggs and young around on their feet during development. The lack of a nest also adds to the noise level of the colonies because they use their unique voice system to call to both their young and their mates.
King penguins are very social birds, and live in colonies with populations of up to 39, breeding pairs. The colonies are generally found on large, sparsely vegetated areas of the islands they inhabit because king penguins avoid climbing. They have been seen huddling together during blizzards to conserve heat.
They have been known to travel up to km from their breeding grounds to forage, and will bathe in the ocean before fishing. The social hierarchies of king penguin colonies are not entirely understood. The penguins compete for positions in the center of the colonies, and these birds are more aggressive and more successful at reproduction than ones further out.
It is thought to possibly relate to the ultraviolet beak spots or plumage. However, no definitive conclusions have been made. Breeding pairs defend an area that is approximately 0. The primary form of communication in king penguins is a two-voice system that is produced by the syrinx, a two-part organ located where the bronchi join. Each part produces sound independently. In penguins, the syrinx is only found in the genus Aptenodytes. The UV reflective beak spots may be used for signaling, but the true use is unknown.
Due to the noisy environment of king penguin colonies, adults repeatedly call out 3 to 7 syllables of varying volumes with two frequencies to locate chicks. The chicks are thought to identify the calls by the lower of the two frequencies because they transmit farther in the seeming chaos of many adults calling at once.
The higher frequency has no documented use. This ability has been termed "cocktail-party effect. King penguins also incorporate movements and behaviors into courtship rituals. Males will produce trumpeting calls and stretch to their maximum height to attract mates. Once a female accepts, the two will stand facing each other and will engage in a series of stretching, bobbing, shaking, bowing, and calling. Like all birds, king penguins perceive their environments through visual, auditory, tactile and chemical stimuli.
Aubin and Jouventin, ; Aubin, et al. Aptenodytes patagonicus travels up to km from its colony to the ocean to feed on cephalopods, small fish, and squid. They can remain underwater approximately 10 minutes and reach speeds of 12 km per hour while diving 25 to m.
Adults take turns returning at irregular intervals to supplement the young that stay in the breeding grounds. During their first winter the chicks predominantly survive from their stored fat. Antarctic fur seals , sub-Antarctic fur seals , leopard seals , and killer whales regularly prey on adult king penguins. Also, brown skuas and giant petrels prey on king penguin chicks. Charbonnier, et al. King penguins occasionally serve as prey for Antarctic fur seals Arctocephalus gazelle , subantarctic fur seals Arctocephalus tropicalis , brown skuas Catharacta lonnbergi and giant petrels Macronectes giganteus.
None of these predators appear to control the king penguin population because they are not a primary food source, and the king penguin population is steadily growing. King penguins act as predators for cephalopods, small fish and squid found in their geographic range, but there is no documentation stating if the populations are controlled by this predation.
Aubin and Jouventin, ; Charbonnier, et al. The hard tick, Ixodes uriae , is a parasite that infests king penguins. The mortality rate of adult king penguins due to hard ticks is unknown; however, there is documentation of death due to hyperinfestation of hard ticks.
A bird louse, Austrogoniodes pauliani , is also a common parasite found on these penguins. Gauthier-Clerc, et al. King penguins are part of the ecotourism business.
During a study of nature-based tourism on the Falkland Islands, king penguins were the most popular of the penguins in the area. All of the tourists visited the king penguin colony, versus only half of the tourists visiting the second most popular penguins species. The tourists also stayed to view the king penguins for the longest time frame at a mean of 63 minutes versus only 19 minutes for the second most popular penguin species. Otley, There are no known negative economic effects of king penguins on humans.
The IUCN Red List states that king penguins have a status of Least Concern based on the following criteria: geographic range is greater than 20, square kilometers, population size is greater than 10, individuals, and the population size seems to be increasing. In birds, naked and helpless after hatching. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. They are shielded with four layers of feathering that keep them warm. King penguins display 70 feathers per every square inch.
The emperor penguin Aptenodytes forsteri is the tallest and heaviest of all living penguin species and is endemic to Antarctica.
The male and female are similar in plumage and size, reaching cm 39 in in length and weighing from 22 to 45 kg 49 to 99 lb. The total population is estimated to be 2. How tall is an average king penguin?
