That is a fallacious argument, you are trying to anectotalize an absurd situation and apply it to millions of years and millions of years of slow evolution.

Wrong. A bird chirpping such a tune is completely within the realm of statistical possibility. Improbable, but possible. And if it were to occur, it occured after millions of years, and countless other birds, chirpped random notes and never quite got it. It has at LEAST as much probability of happening by chance as a DNA molecule, if not more.
