Penguins are birds, but unlike most birds they are not able to fly. They live in the southern half of the world. Many penguins are not afraid of people.
Penguins are very social and live in colonies. They are very cute, very sturdy, and are excellent parents.
A male penguin offers a pebble to a female penguin. If she takes it, they become partners. Some penguins don't build nests, instead they carry their eggs on their feet.
To move quickly penguins flop on their bellies and slide. The legs and feet are set far back on the body, which gives them their upright posture on land.
Penguins can't fly, but they are great swimmers. They use their wings like paddles to swim through the water.
Feet are small so that penguins don't lose too much heat as they stand on the cold ice. They help each other to stay warm: they gather together and keep shuffling around.
Penguins eat seafood. Their main diet is fish and krill. Some penguins don't drink water. Instead they eat snow.
