Depth is perceived when each eye provides a slightly different view of the same scene, when there is an overlap in the field of vision. This is known as binocular vision. Birds such as Owls, which have both eyes facing forward, have binocular vision similar to our own, but most nonpredatory birds have eyes whose fields of view do not overlap enough to provide this ability. Instead, their laterally placed eyes give them a wider total view, the better to detect an approaching predator. Scientist believe that to compensate for their lack of binocular vision, some birds bob their heads, thereby viewing the same subject rapidly from different angles.
In many species, eye color changes as the bird matures and can serve as a means of determining an individual's age. For American Crow, it changes from blue or blue-gray to brown. These birds are not color blind.

Why didn't Malcolm X and Martin Luther King Jr dreams come true yet?
The dream of being color blind has been lost at times for the desire of a handout in some cases. In most cases though, the dream is here. We have a black President and many executives of color. We can not be truly equal until we become color blind and all strive for equality through merit.
