Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably also sing or whistle when you are happy.

Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory.

Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims（宣称）as its own. Only he and his family are welcome there. No other families of the same species（物种）are welcome. Your yard and house are your territory where only your family and friends are welcome. (76▲) If a stranger should enter your territory and want to hurt you, you might shout. Probably this would be enough to frighten him away.

If so, you have actually frightened the stranger away without having to fight him. (78▲)一只鸟也将会做同样的事. But he expects an outsider almost any time, especially at nesting （筑巢）season. So he is screaming（尖叫）all the time, whether he can see an outsider or not. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.

Birds sing loudest in spring when they are trying to attract a mate（同伴）and warn others not to enter the territory of theirs.

You can see that birds have a language of their own. Most of it has to do with attracting mates and setting up territories.

In nature, you may see many insects (昆虫）and animals of different colors. Have you ever wondered why?

Locusts are super delicious food for birds,but it is not always an easy job for birds to catch them.It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops(庄稼). When crops are young,locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do.

Brown bears,tigers and other animals move quietly through forests. They can’t be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the soil(土壤） in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive,they have to hide themselves in the daytime and appear only at night.

Have you ever noticed some even stranger acts? The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over , its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.
