The Eyes Have It

The Bald Eagle ranges over most of North America -- from Alaska, through Canada and down to northern Mexico.

Bald Eagle

The Bald Eagle is a bird of prey. Like other birds of prey, it finds food mainly by sight. It may have the best distance vision of any animal on Earth -- as much as four times sharper than a human's.

Like most predators, the Bald Eagle has binocular vision. Its eyes point forward and are close together. Each eye sees a slightly different view of the same object, which creates a slightly overlapping image in the brain. The brain interprets the overlap as depth.

Depth perception is the ability to see objects in relation to one another. It allows a predator to judge distances as well as the relationship of an object to its surroundings.
