Yeah for genetic diversity! If you are happy with yourself, others will be happy with you too.

First paragraph of the article:
Despair Not, Frumpy Guys
By Julie Rehmeyer
ScienceNOW Daily News
20 April 2006
Always going after the attractive guy can have its downsides. Female birds
gravitate toward flashy fellows, for example, but if they always picked
mates with the same showy traits, the population would eventually become
inbred. A new study of wild finches suggests a solution to the puzzle:
All the males with showy feathers get paired in the spring. In the summer,
still-single females fly far from home, where they settle for males with
more subdued plumage and thereby contribute to the genetic diversity of
the population.
