( ion display fantastic colors but exhibi...)ASU researchers finds novel chemistry at work to provide parrot's vibrant red colors

ion display fantastic colors but exhibit very little variation in color within a species ?at least in colors visible to us. Parrots in general may not be using color in the classic cases of mate choice or competitive ability," he said. "Exactly why they are so uniformly colored remains an interesting mystery to us ?one we want to investigate."

"There is a sea of colors in birds," he added. "Our goal is to learn why there is such a diversity from an evolutionary standpoint."
