![]() ![]() With eagle eyes, we would swivel our heads constantly. With our eyes angled 30 degrees away from the midline of our faces like an eagle's, we would see almost all the way behind our heads with a 340-degree visual field (compared to normal humans' 180 degree field) this would confer a clear advantage in hunting and self-defense. On top of the ability to see farther and perceive more colors, we would also have nearly double the field of view. It's perhaps easiest to consider our new powers in the context of how eagles use them: for hunting. Įagle vision wouldn't change how we perform most daily activities - such as reading computer screens or the newspaper, or finding milk in a crowded refrigerator - but how we perceive the world and use our eyes would certainly be different. We can't even guess what they're subjective sensation of ultraviolet light is," Hodos said. "Suppose you wanted to describe the color of a tomato to someone who was born blind. But there's no way to know what these extra colors, including ultraviolet, look like. They see colors as more vivid than we do, can discriminate between more shades, and can also see ultraviolet light - an ability that evolved to help them detect the UV-reflecting urine trails of small prey. On top of sharp focus and a central magnifier, eagles, like all birds, also have superior color vision. Some investigators think this deep fovea allows their eyes to act like a telephoto lens, giving them extra magnification in the center of their field of view," Hodos told Life's Little Mysteries. "Our fovea is a little shell or bowl, while in hawk or eagle it's a convex pit. © 2014 Tune In to Nature.Second, they have a much deeper fovea, a cone-rich structure in the backs of the eyes of both humans and eagles that detects light from the center of our visual field. So the next time you give the “eagle eye” to a raptor, chances are, it saw you first.īird sounds provided by The Macaulay Library of Natural Sounds at the Cornell Lab of Ornithology, Ithaca, New York. That's like you driving at forty miles an hour, and being able to look back to where you were when this BirdNote started and see a jack rabbit. There, it spots the minute movement of its favorite prey, a rabbit, over a mile away. So when hunting in open country, the Golden Eagle uses its seven-foot wingspan to ride thermals high into the air. The density of rods and cones within a raptor’s eye may be five times more than in your own eye. Look at the back of your hand: your rods register the overall shape, the cones register details such as contour and color. ![]() The secret to the bird’s exceptional vision is the density of visual cells, the rods and cones of its retina.
