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

Some scientists believe that birds do sing some of 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 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. If a stranger should enter your territory and threaten 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. A bird does the same thing. But he expects an outsider almost any time, especially at nesting(筑巢) season. So he is screaming 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 the spring when they are trying to attract a mate(配偶)and warn others not to enter the territory of theirs.

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

Make new friends, but keep the old. One is silver, and the other gold.

This song expresses a nice rule: increasing friends. Sometimes things actually work out that way. I’ve met adults who’ve said, “We’ve been friends since kindergarten!” A friend who has known you forever is a treasure. But friendships don’t always last — especially for children.

When I was growing up, my family moved about every three years. The advantage of this was that I got to see different parts of the world, and it made my family very close. I also learned to be pretty good at making new friends, and, to keep in touch with old friends, I became a great letter writer. But I always admired those kids who stayed in one place and kept their friends for a long time. I didn’t learn that children’s friendships can disappear even when no one moves until I was much older, with children of my own.

Sometimes friendships end in quarrels and hurt feelings. But perhaps the most painful end to a friendship is the one-sided rejection — one friend turns away, or chooses someone else as a close friend, and the other child is left feeling sad and wondering why this thing happened. The end of a friendship is often sad, but it’s not necessarily a bad thing. Often the end of one friendship makes more room for other friendships to grow.
