People usually sing because they like music or because they feel happy. They express their happiness by singing. When a bird sing, however, its song usually means much more than that the bird is happy. Birds have many reasons for singing. They sing to give information. Their songs are their language.

   The most beautiful songs are sung by male (cock) birds. They sing when they want to attract a female (hen) bird. It is their way of saying that they are looking for a wife.

  Birds also sing to tell other birds to keep away. To a bird, his tree or even a branch of tree, is his home. He does not want strangers to comming near him, so he sings to warn them.

If a bird cannot sing well, he usually has some other means of giving important information. Some birds dance, spread out their tails or make other sings. One bird has a most unusual way of finding a wife. It builds a small garden of shells and flowers.

Mozart, who was born on  January 27, 1756, in the Austrian city of Salzburg, was neither the first nor  the last child prodigy, but he was certainly the  greatest. He was born into a moderately prosperous family where his unmatched musical genius made itself known extremely early. Mozart began learning to play the harpsichord at three and his earliest known work was  composed in 1761 when  he was five, the age at which he also first appeared in public.

From the age of six, when his  father took him on the first foreign tour, Mozart toured the courts and musical centers of Austria, Germany, France, England, Holland, Switzerland, and Italy. It has been calculated that Mozart spent  almost a third of his short life - he died at the age of 35 -  traveling. As Mozart matured, he continued to tour and  give concerts. Mozart also wrote a lot of  operas. His first opera, mitridate, Re di Ponto, was performed in Milan when he was 14, and it was the first of money   successes in the theatre.
