Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all，you probably 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(声称)as its own. Only he and his family are welcome there. No other families of the same kind are welcome. Your garden and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten(威胁)you，you might shout. Probably this would be enough to frighten him away.
If so，you have actually scared 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 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.

Joyce interviewed some young people. Here are their opinions.
Harold：I don't quite understand why they are so mad about the childish game， Maybe they are just not confident enough to face the real world.
Allan：I enjoy putting some "bugs" in my friends' gardens and we've become closer because of the game. Having fun together is the most exciting thing about it.
Laura： You know， people in the city are longing for(渴望) the life in the countryside. It reduces my work pressure(压力)；besides，it gives me the exciting experience of being a "thief".
