As the weather outside gets colder, learn all about these unique birds that endure some of the harshest winter weather in the world!

* Did you know the different kinds of penguins make up the largest family of flightless birds in the world?

* All penguins live in the southern half of the world. There are no penguins in the Northern Hemisphere.

* Emperor penguins may eat 30 pounds of food at one time.

* A penguin’s black and white “suit” helps to hide the penguin from predators when it is swimming in the ocean. The white underside of the penguin blends with the bright light coming from above.

* Penguins usually swim at about 15 miles per hour. This is equal to the speed of the fastest human runner and four times faster than the fastest human swimmer.

* Most penguins live in large colonies called rookeries when they are on land. Some of the largest rookeries have over one million penguins in them.

* Most penguins return to the same place every year to have their babies. Some of them may swim thousands of miles to get there.

* Emperor penguin babies are hatched in the worst weather on Earth. Female Emperors lay their eggs during the coldest months of the Antarctic winter. The males keep the eggs warm for six weeks in possibly 80 degrees below zero weather with blizzard winds of up to 120 miles per hour.

* Emperor and King penguins carry their eggs around on their feet instead of building nests.

* Like humans, penguins are warm-blooded and make heat inside their bodies. This means they can stay warm if they can keep most of this heat from leaving their bodies. To keep the heat from escaping, their bodies have several layers of insulation.

Now it’s your turn. Try this fun activity to see for yourself how penguins keep warm in cold climates.
