Animal You | Emperor Penguin | The adult Emperor Penguin stands up to 110-130 cm (43-51 inches) tall. With men weigh more than women heavier birds fifth, after the larger species of ratites. Weight varies by season, as male and female penguins lose substantial weight in raising offspring and egg incubation. A male emperor penguin, Antarctic cold for more than two months to object to their eggs to protect against extreme cold. Penguins Most men lose about 12 kg (26 lb), pending their children to come. After the breeding season this drops to 23 kg (51 lb) for both sexes. Like all penguin species, the Emperor has a streamlined body to minimize drag while swimming, and wings, stiff, flat flippers. The adult has deep black dorsal feathers. 'S head, chin, neck, back, chest and part of the tail fins The black plumage is clearly defined by the bright plumage elsewhere.
The upper 8 cm (3 inches) long bill is black, and the lower jaw is pink, orange or purple creature. The Emperor Penguin chick is typically covered with silver-gray down and has. Chicks weigh around 315 g (11 oz.) The emperor penguin dark plumage fades from November to February, before the yearly moult in January and February. Emperor Penguin feathers come from the skin after a third of its total length has grown and is lost before old feathers to go, to reduce heat loss. The annual survival of emperor penguins is measured at 95.1%. The emperor penguin breeds in the cold environment of all species of birds, the air temperature reaches -40 ° C (-40 ° F) and the wind speed can reach 144 kmh (89 mph). Water temperature is a frigid -1.8 ° C (28.8 ° F), much less than the average weight of the emperor penguin, the temperature of 39 ° C (102 ° F). The type is modified in various ways to the heat loss.
The resulting fat layer impedes the mobility of the Emperor on land compared to less insulating fat cousin, the Magellanic penguin. With around 100 feathers that one square inch (15 feathers per cm 2), with the highest density of each spring bird species. An extra layer of insulation is formed by separate tree with soft bristles between feathers and skin. Emperor penguins are able to regulate the temperature (to maintain body temperature). Without their metabolism, over a wide temperature range so-called neutral temperature range extends from -10 to 20 ° C (14 ° to 68 ° F). At temperatures above 20 ° C (68 ° F), an emperor penguin can change how your body temperature and metabolic rate, increases heat loss. Penguin bones fixed place of air filling, so the risk of barotrauma eliminates mechanics. While diving, the Emperor penguin oxygen consumption decreased, and your heart rate can be reduced as low as 15 to 20 beats per minute and closed non-essential organs, facilitating longer dives.
The emperor penguin is a circumpolar distribution in the Antarctic almost exclusively between 66 ° and 77 ° south latitude. Breeding colonies are usually in areas where ice cliffs and icebergs from the wind. Around 80,000 pairs breed in the Ross Sea sector. Important breeding colonies at Cape Washington (20,000 to 25,000 pairs), Coulman Iceland in Victoria Land (around 22,000 pairs), Halley Bay, Coats Land (14.300 to 31.400 pairs), and Atka Bay in Queen Maud Land is (16,000 pairs). Vagos have heard Iceland, South Georgia was incorporated in New Zealand and emperor penguin predators are birds and mammals. The Southern Giant Petrel (Macronectes giganteus) is the predominant land predator of chicks, responsible for up to 34% of chicken deaths in some colonies, but often intercept dead penguins. Predators are known in aquatic mammals: the leopard seal (Hydrurga leptonyx) have a copy number of adults and chicks shortly after entering the water and the Orca (Orcinus orca), which takes adult birds.
