"They have two foveae, or centers of focus, that allow the birds to see both

"Eagles, like all birds, have color vision. An eagle's eye is almost as large
as a human's, but its sharpness is at least four times that of a person with
perfect vision. The eagle can probably identify a rabbit moving almost a mile
away. That means that an eagle flying at an altitude of 1000 feet over open
country could spot prey over an area of almost 3 square miles from a fixed
position."
