Females Are Attracted By Males Who Wear Makeup

A study published in journal Current Biology, proved that male barn swallows are considered sexy when their breast feathers are dark rust-color. So scientists placed makeup to turn the wimpiest of male barn swallows into sexiest males. These marked-up males were more attractive to females and mated more often than the others. Surprisingly, they have found that the more attractive appearance also triggered changes to the male’s body chemistry, and increased the testosterone level.
