The male Emperor penguin will stay at the breeding site and care for the egg with the Emperor penguins baby inside by placing it in his warm brood pouch. The shape varies among species. In emperor and king penguins the egg is rather pear-shaped, with one end tapering almost to a point. The Rockhopper penguins are distinguished from the Macaroni penguin and other members of the crested species by their smaller size and the thin, vivid yellow tassels which extend along the sides of the brow but do not meet between the eyes. 8.

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. Successful copulation is observed in under 50% of cases and is followed by similar behaviour. These Penguins are serial monogamous creatures. 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. Their nests are usually 40 centimetres in diameter and 15 centimetres high.
