Interestingly, penguins recognize and feed only their own chicks, and the males find their babies by listening for distinctive calls. Parents take turns feeding the chicks and returning to the sea to feed themselves. The migration tracks are traveled over and over by both parents for about nine months.
When summer arrives and the chicks have matured in December, they travel with their parents to the sea and learn to swim for their own food. The chicks remain at the breeding grounds at sea until they mature, at about 4 or 5 years of age.
When they find mates, they repeat the migration patterns of their ancestors. Little is known about how penguins find their way during migration, but scientists have concern for the future. A few other penguin species, such as the Magellanic and the Humboldt penguins, migrate for the purpose of finding food, but the instinctive travels of the emperor penguins are legendary.
Rookeries are usually situated at the base of permanent ice cliffs which offer some shelter from the freezing weather. The ice from these cliffs must not melt until the chicks are fully fledged which can take until the early summer months November in the southern hemisphere. This is why emperor penguins will travel so far inland to breed. As soon as the egg is laid it is passed to the male who carefully balances it on his feet and then covers it with an abdominal fold of skin.
Almost immediately then, the female leaves the male and joins other females from the colony as they make their way back to the sea to feed up. The males are simply left "holding the baby" for up to two months.
Without the warmth and protection provided by the male's body and the insulation provided by the feet, the chick inside the egg would quickly die, and so the male penguin has to remain where he is until either the egg hatches or the female returns.
