From Pathfinder Wiki
The Wedge-tailed Eagle have sophisticated binocular vision which enables them to accurately assess distances and pinpoint their prey. Their eyes also are equipped with bony rings which can squeeze and elongate the eyeball. This has the same effect as a telephoto lens on a camera. It enlarges the image seen by the bird. This is very unusual.
