Do You know that the tern migrates between the North and the South? Try to imagine having two homes, one at each end of the world. That is exactly the way the arctic tern lives. It spends winter in Greenland and Alasca. Of course the tern spends much of its time traveling between the two poles, which are 12,000 miles apart!

... that the fastest bird is a swift? It can fly faster than 200 miles an hour! When it migrates, this bird makes a flight of 1,500 miles in about seven hours.

... that the only bird which can walk upright, like a man, is the penguin? But the penguin not only walks like a man, it looks like a man in a suit, with a black coat, white shirt, and black bow tie. When it wants to move quickly on land, it lies down and slides along on the ice.

... when a bird sings?

Birds usually sing when they express their feeling of love or when they want company and call their friends. At other time they sing simply for joy, as the lark sings.

The feelings which birds sing about are always happy feelings. When a bird is ill or unhappy, it never sings. It sings only when it is well.

... why an owl comes out at night? Many animals, and some other birds besides owls, are active during the hours of night.

If we want to understand why an animal comes out at night, or why it comes out in the day-time, we must know what makes an animal more active at one time of the day than at another. You can usually answer this question when you know what this or that animal eats.

Owls eat mice and other small animals which are active during the hours of night. That is why owls can see when it is rather dark. Their eyes open very widely so that they can catch every ray of light that there may be.
