Is it true that chickens can only see in black and white?

chickens may have "bird brains," eyes different matter. when comes color vision, these farm fowl have bested humans in many ways, new study finds.

superior color vision comes down well-organized eye, structurally speaking, researchers say.

mapped 5 types of light receptors in eyes of chickens. discovered receptors laid out in interwoven mosaics maximized chicken's ability see many colors in given part of retina, light-sensing structure @ of eye.

"based on analysis, birds have one-upped in several ways in terms of color vision," said study author dr. joseph c. corbo of washington university school of medicine in st. louis, mo. "color receptor organization in chicken retina exceeds seen in other retinas , in mammalian retinas."

birds owe exceptional color vision not having spent period of evolutionary history in dark, according corbo.

night-vision relies on light-sensitive photoreceptors in retina called rods, while daytime vision relies on receptors called cones.
