Bird Eye Spots Enemies And Food
By Rodger G Allenby
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?
Similarities Between The Human And Bird Eye
The bird eye and the human eye share many of the same structures.
Both eyes have many of the same functions as well. A few of the
basic structures of a bird’s eye, no matter the species of birds,
are cornea, retina, anterior chamber, iris, lens, and eyelids.
Humans have these same structures but the difference is how the
structures work. Take for example the size of the eye. A human
eye is only 1% of their body. A starling’s eye is 15% of its body.
Birds can see a great deal better than humans but we do have the
advantage of being able to move our eyes.
Spotting Enemies And Their Prey With A Bird Eye
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.
If The Eye Of A Bird Is Damaged, Then The Bird May Die From Starvation
Humans can get by without their eyesight. There are many devices
and advancements in medical science that allow for humans to review
their options and 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.

Little Known Birds Facts....
What type of equipment do I need to observe birds?
Your eyes are your most important equipment.
But you will need some help seeing the birds. If you are just
starting out bird watching, it is probably a good idea not to
invest a lot of money in the pastime until you know that you actually
have the time and money to invest in it. You can go to a local
retail store or sporting goods store and buy a reliable binocular
to help you see.
Once you have progressed in your bird watching
skills, then you can move up to more expensive binoculars and
other electronic devices to help you capture the bird on film.
You can even buy a binocular with a built in digital camera. Start
slowly acquiring your equipment and you will know that you are
making a great investment into your hobby. It would be a shame
to pay a few thousand dollars on gear and equipment only to find
out that you hate being outdoors and walking through fields or
woods.
