The eagle is one the largest and most powerful birds of prey. Soaring high above the earth, spying its prey with its keen eyes, the eagle presents a majestic picture. Eagles are notable for their powerful set of eyes. Even though their eyes are just slightly larger than human eyes, they can see up to 3½ times better than a person with perfect vision. An eagle can see a moving rabbit from a mile away, and can see a fellow eagle soaring 50 miles away!
There are several species of eagles, which differ in size, looks and habits. But all eagles have large, strong bills and powerful claws, or talons. The bird usually builds its nest (called an "eyrie")in a remote place such as a high cliff where it cannot be disturbed. If it chooses to build in a tree, it will choose a spot that is 50-150 feet above ground. The nest is built of sticks and is used year after year.
