How can an eagle see animals on the ground while soaring high above ground?
Eagles have extremely keen vision. Their eyes are specially designed for long distance focus and clarity. The eye is large with a large retinal surface area and a high concentration of cones (eyes have rods and cones which allow sight) which aid in visual acuity and color perception. It has been estimated that eagles can see 3-4 times farther than humans and that they can see another eagle soaring nearly 50 miles away.
