帝企鵝是唯一在南極大陸沿岸過冬的鳥類，并在冬季繁殖。雄性皇企鵝為了呵護雌企鵝產下的卵，會在隨后的兩個月或更長時間內不吃不喝，全心盡力用自己的身體給后代取暖。孵卵時，雄企鵝將卵放在兩腳的蹼上并用肚皮蓋住，在這其間，雄企鵝的體重將減輕11公斤。

Penguin（帝企鵝）: A father Emperor penguin（帝企鵝） withstands the Antarctic cold for 60 days or more to protect his eggs, which he keeps on his feet, covered with a feathered flap. During this entire time he doesn't eat a thing.

Most father penguins lose about 25 pounds while they wait for their babies to hatch. Afterward, they feed the chicks （剛出生的小企鵝） a special liquid from their throats. When the mother penguins return to care for the young, the fathers go to sea to eat and rest.
