    The name “bird’s eye” has been given to many companies and mapping mechanisms. Who could forget Bird’s Eye vegetables? There are many applications that want you to make the connection between the bird eye and high quality products or software that can show map details for miles. The bird’s eye is a remark that is often tossed around when someone is referring to a high vantage spot that allows them to see the lay of the land for several miles. How much do we owe these wild animals?

    Did you know that your eye and the bird’s eye have many of the same structural features? Both the human eye and the bird eye have a cornea, retina, iris, lens, anterior chamber and eyelids. Some of these structures function in the same way for both humans and wild birds/domesticated birds.

    The obvious difference is the size of the eye in comparison to the rest of the body. A starling’s eye is 15% of their body mass, whereas a human’s eye is only 1%.

    The size of the eye depends on the bird species. Owls, for example, have huge eyes that allow them to take in more at once. For a wild bird that is important because it means that they can spot enemies and their prey much easier. Owls cannot move their eyes so they rotate their heads.

    How far do they rotate their heads? They rotate a whopping 200 degrees. Another difference to be found is the number of eyelids a bird has over humans. The human eye only has an upper and lower eyelid.

    All species of birds have three eyelids. They have an upper, lower and a nictitating membrane that cleans and protects the eye. Another difference is in the positioning of the eyes.

    Humans and most wild animals, especially predators, have eyes that are not as centralized as a bird’s eye. A bird’s eye is on the front of the skull and they lack the ability to see very far to the sides. This is why birds turn their heads often.

    Human’s can get by without their eyesight. There are many devices and advancements in medical science that allow for humans to compensate for vision loss. Wild birds do not have this luxury.

    If their eyesight is damaged, then they will undoubtedly starve or die without outside help from a conservation or rescue group. The bird eye may just be an organ but it is one that these two legged, winged wild animals cannot live without.
