Emperor penguins are the largest penguins on the earth. The largest emperor penguin is over a meter tall and up to 40 kilograms heavy.

For many months each year, emperors live near the sea in large groups called colonies. However, in May, the weather gets colder and ice covers large part of the sea. Each colony moves many kilometers from the water. There, each mother penguin lays just one egg. Then all the hungry mothers must walk back to the sea to find food. The father penguins put their eggs on top of their feet, under a special piece of skin called the brood pouch.

Working together

For two months, the father penguins keep the eggs safe and warm. They do this through some of the coldest weather on Earth. By July, it is winter in Antarctica. Most animals leave for warmer places, but the father penguins stay. In this time, without food, a father penguin can lose almost half of his body weight, so he is thinner.

New Life

By August, the babies begin to hatch. The mother penguin returns just in time to see her baby come out of its egg. The chick is then moved to her brood pouch. This can be difficult. If the chick falls, it may freeze quickly because of the really cold weather, so the penguin parents must be very careful. Once the chick goes into its mother’s brood pouch, the father penguin can go back to the sea to find food.

Growing up

Over the next few months, penguin parents take turns going to the sea for food. They each make the trip over a few times, bringing back food for the chick. The chick grows quickly and is always hungry.

Into the Water

By December, winter is ending. The chick is five months old and can live by itself. Soon it goes into the water for the first time. It will swim and eat. By next April, it goes back here. After a few more years, it, too, will start its own family.
