After the female lays her eggs, her nutritional reserves are depleted and she must return to feed at sea for two months.
This means that the responsibility for keeping the egg warm through, protected from the freezing Antarctic winter, lies with the father.
The father penguin broods the eggs by balancing them on his legs and protecting them with a fold of skin called a "hatching pouch". The egg incubation lasts 2 months, during which the males do not eat and must withstand the Antarctic cold, while the females will return when the egg hatches.
