Here’s a quick test: What makes the eyes of birds of prey different from that of most other birds? The answer is binocular vision. The eyes of most birds are located on the sides of their heads, and see independently. But birds of prey have eyes located nearer the front of the head, so that the eyes work together and have greater accuracy when it comes to depth perception.

Now, another question: what makes the eyes of birds of prey different from that of humans? There are several correct answers to this one, but this time we’ll say that birds of prey have more rods and cones in their eyes than humans do, which allows the birds much more visual acuity. A golden eagle, for example, can see an 18-inch rabbit from two miles away. Not all birds of prey have such astounding vision, however–the American kestrel, for example, cannot see any better than a human.

Last question: Do birds of prey see in color? Yes, they do. It is apparently important to identifying prey and in reproductive behavior. One more interesting fact is that they have a disproportionally large number of sensory cells in the upper half of their retinas. This means that when they look down on the ground from the sky or a perch, they can see better than when they look up to the sky above them. To look above, birds of prey will turn their heads upside down to see better!
