1.Scientists mapped out 5 different types of light receptors in the chickens eye.
2.Vision comes from light-sensitive photoreceptor cells in the retina.
3.Color receptor organization in the chicken retina greatly exceeds that seen in most other retinas and certainly that in most mammalian retinas.
4.Vision comes from light-sensitive photoreceptor cells in the retina
5.It is to believe that birds are descendants of dinosaurs.

during the studying of a chivkens eye, researchers have found that they are made up of more complex light receptors. this eneables them to capture more color in their retina which makes them see better. Scientists have concluded that this is because birds were not nocturnal during the period of evolelution like other animals did. another reason for the chicken/bird’s vision is so enhanced is so that they can see the colorful plumage of other birds duriing mating season and so that they can see what color the berries or plants are that they are eating. humans have two ways that they can see: rods for night vision, which capture more light, and cones, which capture color in daylight. during their study, scientists found that the chickens had multiple cones to collect more color.

~Researchers have found a biological masterpeice in the eye of a chicken.

~Birds have ‘one-upped’ us in the terms of color vision.

~Vision comes from light-sensitive cells in the retina.

~Night vision relies on recepters that are called ‘rods.’

~Day-vision relies on other receptors know as ‘cones’.

1.They discovered the receptors were laid out in interwoven mosaics that maximized the chicken’s ability to see many colors in any given part of the retina.
2.Birds, now widely believed to be descendants of dinosaurs, never spent a similar period living mostly in darkness. As a result, birds have more types of cones than mammals.
3.Most avian cones have a specialized structure that Corbo compares to “cellular sunglasses.
4.Corbo speculates that extra sensitivity to color may help birds in finding mates, which often involves colorful plumage, or when feeding on berries or other colorful fruit.
5.Many of the inherited conditions that cause blindness in humans affect cones and rods.

1.The super vision helps birds find mates and stuff.
2.Researchers at Washington University School of Medicine in St. Louis have looked at chicken’s eyes and found an interesting discovery.
3.Birds likely owe their superior color vision to not having spent a period of evolutionary history in the dark, according to Corbo.
4.They have seen a masterpeice of design.
5.Scientists published their results in the journal PLoS One.
