A bird sings because it's what it is born to do. When it pulls air into it's tiny little lungs and pushes that air out of it's throat, it makes the sound he was born to make, the sound that no one had to teach him to sing. Mother Bird must nurture the little bird until he is strong and ready to fly. When he is ready, he will go his own way. He will learn, and explore, and grow. Someday, he might come back to the very place where he hatched. In the very same tree even. He knows the way home. No one has to has to show him.
