Even Charles Darwin struggled to explain why the bird should have this burdensome trait. When there are many potential danger related to the colourful tail, why this bird got this trait. Darwin finally got the idea of sexual selection, which provides an advantage in the competition for mates and that outweighed other disadvantages. While humans are attracted to symmetrical faces and other outward signs of fitness, these birds are attracted to colourful tails. The male specific traits are evolved with the changing preferences of females. When the female tastes change, these traits go away.
