Found in the Antarctica, the most desolate, unfriendly and inhospitable place on Earth being the coldest. the Emperor penguin bird is an enigma. How they fight off the freezing cold, find food for existence and reproduce their species are wonders that are worth knowing.

Summary

  • There are 17 or 18 known species of penguins and all are interesting. It puzzles the imagination why they can’t fly despite their wings. They live in desolate and cold places of the earth. One of them the Emperor penguins thrive in no other place but the Antarctica. It is a wonder how they can survive the coldest winter temperature at – 89.2 degrees centigrade. Particularly, the Emperor penguins are the largest of the species; they breed and lay eggs during winter time. Each Emperor female penguin lays only one egg and its equally interesting to know who incubates the egg and how the female penguin lays her egg without a nest because- unlike others- Emperor penguins don’t build nest. Penguins are great swimmers and divers. They can catch fish under floating ice. Researchers say they have amazing swimming speed and dive thousands of feet underwater to catch fish, silverfish, squid and krill for food.
  • Why do penguins prefer to live in the Antarctica which is of all places on earth the most desolate, the cruelest place being the coldest. Why don’t the find other pleasant places like other migrating birds? The answer I think is they were purposely made by God to make the Antarctic a little lively. Being born there, they have no other choice but to prepare and hone themselves ready to fight the kind of arctic life required of them. They are there by nature.
  • It's common knowledge that the female Emperor penguin lays only an egg during a nesting session and goes out to the sea to catch fish to replenish nourishment, leaving her egg to Father Emperor for incubation. What boggles the mind is how is the transfer done? Here's one research work which is quite satisfactory:
  • "At the end of May, the female has lost almost a third of her weight when she lays her
    only egg. She is standing to lay this egg, and it is a critical time. Under no circumstance can the egg roll onto the ice, because in just a few seconds, it would freeze. So the female immediately slides the egg onto her feet and makes it disappear in her incubating pocket, under her belly. But before this can happen, just one day after laying the egg, the couple will face its first challenge, a very delicate and coordinated effort: transferring the egg from the feet of the female to the feet of the male. Neither of them can fail because the egg is fragile, the terrain uneven, and the exercise can be fatal in case of a mistake. After many songs and dances, the female
    moves back, pushes the egg out onto the ice, while the male takes his beak to push the egg immediately onto his own feet. Again, there is the danger the egg will freeze. There are dozens of lost eggs on the edge of the colony, which are a testament to how difficult this transfer actually is, and to the fact that it requires total harmony between the parents".
  • Unlike other birds, Emperor penguins don't build nest where to lay and incubate egg. This is how they do it: "They stand upright while incubating a single egg on the tops of their feet under a loose fold of abdominal skin. Under this loose fold is a featherless patch of skin called a brood patch, which contains numerous blood vessels that, when engorged with blood, transfer body heat to the eggs."
  • The Emperor Penguin is a strong bird. There’s a report that six men, trying to capture a single male penguin for a zoo collection, were repeatedly tossed around and knocked over before they could tackle the bird. The American physiologist Gerry Kooyman attaches automatic dive-recording devices to Emperor Penguins in 1971 and found that the species reaches depths of 265 m (869 ft), with dive periods of up to 18 minutes. Later research revealed a small female had dived to a depth of 535 m (1,755 ft) near McMurdo Sound.

  • There are several species of penguins. The largest of all species is the Emperor Penguin, reaching a measure in adulthood of 3.7 ft. (1.1 m) and weighing in about 74 lbs on average (35 kg). Males can easily weight 84 lbs at the beginning of breeding season but its weight will drastically decline over the season to about 51 lbs. This is because during the time he is incubating the egg, he does not eat anything. The female lays a single egg and leaves out to sea to feed, the egg is then incubated by the male while the female is gone. Afte the chick is hatched, the Emperor Penguin parents subsequently take turns at sea alternating with caring for their chick in the colony.
