Eagle's eyes are characterized by good eyesight and strong perception. Because the eagle's eyes have three kinds of photosensitive cells, it sees colors, and there are still a few cells in the eagle's eyes that can sense ultraviolet rays and can see more complicated colors than humans. Eagles are carnivores. They catch small animals, such as mice, snakes, rabbits or birds. Hawks usually move during the day. Even if they fly at an altitude of 1000 meters, they can clearly see their prey on the ground. They are famous for their insight.
