Emperor penguins go to great lengths to care for their children. 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 100 cm (39 in) in length and weighing from 22 to 45 kg (49 to 99 lb). Male penguins take egg-sitting duties for weeks while mom heads to sea to hunt fish for her soon-to-hatch offspring. Eggs are generally laid in the months following September till November and that go through an incubation period of around 40 days, in which the males also participate. Feathers of the head and back are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches. Chinstrap penguins make a round nest out of stones and pebbles. Female penguins lay their eggs on the shore. The mothers keep part of the food they got in their stomach, which regurgitate to feed their newborn chick. As mentioned above, the egg needs to be incubated for approximately 65 days before the Emperor penguins baby is ready to emerge. EmperorPenguins.net explains that when a female emperor or king penguin lays an egg, its mate immediately places the egg on top of his feet, away from the ice, and incubates it with a fold of skin. As penguins do not normally lay so many eggs, Mr. Popper attributes this to the change in climate the birds have experienced. They don’t even use a small pile of rocks like other species of penguins. Penguins take very good care of their eggs. Instead, a single egg for each mated pair is incubated on a parent’s feet and kept warm by a flap of skin called a brood pouch. Male and female Rockhopper Penguins are very similar in appearance, though males are larger. Once the father has the egg and starts protecting it, the female returns to the sea to feed and returns to the colony almost after two months, but before the hatchling breaks the large and thick shell of its egg. When she comes back he leaves to look for food. The female emperor penguin lays a single egg which is carried on the feet and covered with a fold of skin. He balances the egg there for about 64 days, during which time the female travels to the ocean to hunt. As there are no nesting supplies available on the ice mass, emperor penguins must create a safe, warm environment for the eggs using their own bodies. Female Emperor Penguins then leave for the open ocean where they forage for food for two whole months, leaving the males to look after the eggs during the winter months. This makes for happy penguins, but strains the family budget. The female lays one egg in May or June, transfers the egg to the male, and returns to sea to feed while the male incubates the egg in his brood pouch for about 65 days. The egg is quickly transferred to the male who rests it on his feet to stop it from touching the frozen ground, and covers it with a warm brood pouch that keeps the egg warm. After giving birth, the female emperor penguin will leave the family behind to replenish her body at sea, leaving the father to take on all of the parental responsibilities. Sometimes the female takes the first shift. Their nests are usually 40 centimetres in diameter and 15 centimetres high. The male penguin will sit on the egg to protect it until she returns.
