Birds in general can see colors better than most mammals and can perceive light radiation even in the ultraviolet. Moreover, as in many mammals, even in birds the right and left eyes have different characteristics, which make them specialized in receiving visual information with different modalities and efficiency, due to the "lateralization" of the brain. In practice, the left eye, controlled by the right hemisphere, is very susceptible to new and attractive stimuli, and is very useful when predators must be avoided.
The vision with the right eye, controlled by the left hemisphere, instead confers greater capacity for concentration and categorization; focuses on a single stimulus. It is also used by migratory species for orientation.
