Eagle Sight & Human Sight
Eagles are
beautiful birds known for their majestic frame and incredible hunting
abilities. They have the reputation of having one of the best visions on the
planet. What makes ‘eagle eyes’ a thing of envy? Let’s find out.
VISUAL ACUITY
Visual acuity is
the eye’s ability to separate details of an object without any blur. The normal
or a ‘good’ vision for a human is 20/20. Eagles, however, have retinas with
cones and have a much deeper fovea—a cone-rich structure in the back of the
eye. These give them a visual acuity of an impressive 20/5, or 20/4 which
allows them to hunt even the tiny prey from hundreds of feet up in the air.
HOW IS THE EAGLE’S VISION MEASURED
There is a
scientific set-up to determine the strength of eagle’s vision. The birds are
trained to fly down a long tunnel where two TV screens are kept at the end. One
screen has a display of striped pattern to attract the eagle towards it and when
they land on that screen, they are given a treat. The birds’ acuity is tested
by changing the width of the stripes and determining from what distance the
eagles begin to turn in the correct direction.
THE RANGE AND VIVIDNESS OF COLORS
Eagles have the ability
to see colors more vividly than humans can. They can even see ultraviolet light
and pick out more shades of one color. Their ability to even see the UV light
allows them to see the bodily traces left by their prey. Mice’s and other small
prey’s urine is visible to the eagles in the ultraviolent range, making them
easy targets even a few hundred feet above the ground.
POSITIONING OF THE EYES
Human eyes are
positioned at the front of the heads, giving us a binocular vision and a
peripheral vision of just 180 degrees. We can only see complete images when we
use both eyes, as closing one will block a portion of vision that was visible
with that eye. The use of both eyes gives us that ability to determine the
depth of field and help us realize the speed of any moving object.
Unfortunately, our peripheral vision is quite poor.
On the other hand,
an eagle’s eyes are rotated towards the front of the head and are angled 30
degrees from the midline of the face. This allows them to have a 340 degree
field of vision. Their peripheral vision is quite impressive, which greatly
assists these predatory birds.
ABILITY TO FOCUS CLEARLY
The ability to
switch between seeing things that are near and far clearly require quick
changes in the lens of the eyes, which is known as accommodation. As humans
age, the muscles required to change the shape of the lens get stiff and become
less effective, requiring us to wear glasses to see distant and nearby things
equally clear. However, the eagles not only have a lens that changes the shape
to accommodate the changing distance but even their cornea has the ability to
change shape to better focus on near and far objects.
7 Principles Of An Eagle – Dr. Myles Monroe
PRINCIPLE 1
Eagles fly alone at high altitude and not with sparrows or other small birds. No other bird can got to the height of the eagle. Stay away from sparrows and ravens. Eagles fly with Eagles.
PRINCIPLE 2
Eagles have strong vision. They have the ability to focus on something up to five kilometers away. When an eagle sites his prey, he narrows his focus on it and set out to get it. No matter the obstacles, the eagle will not move his focus from the prey until he grabs it. Have a vision and remain focused no matter what the obstacle and you will succeed.
PRINCIPLE 3
Eagles do not eat dead things. They feed only on fresh prey. Vultures eat dead animals, but eagles will not. Be careful with what you feed your eyes and ears with, especially in movies and on TV. Steer clear of outdated and old information. Always do your research well.
PRINCIPLE 4
Eagles love the storm. When clouds gather, the eagles get excited. The eagle uses the storm’s wind to lift it higher. Once it finds the wind of the storm, the eagles uses the raging storm to lift him above the clouds. This gives the eagle an opportunity to glide and rest its wings. In the meantime, all the other birds hide in the leaves and branches of the trees. We can use the storms of life to rise to greater heights. Achievers relish challenges and use them profitably.
PRINCIPLE 5
The Eagle tests before it trusts. When a female eagle meets a male and they want to mate, she flies down to earth with the male pursuing her and she picks a twig. She flies back into the air with the male pursuing her. Once she has reached a height high enough for her, she lets the twig fall to the ground and watches it as it falls. The male chases after the twig. The faster it falls, the faster he chases it. He has to catch it before it falls to the ground. He then brings it back to the female eagle. The female eagle grabs the twig and flies to a higher altitude and then drops the twig for the male to chase. This goes on for hours, with the height increasing until the female eagle is assured that the male eagle has mastered the art of catching the twig which shows commitment. Then and only then, will she allow him to mate with her. Whether in private life or in business, one should test commitment of people intended for partnership.
PRINCIPLE 6
When ready to lay eggs, the female and male eagle identify a place very high on a cliff where no predators can reach. The male flies to earth and picks thorns and lays them on the crevice of the cliff, then flies to earth again to collect twigs which he lays in the intended nest. He flies back to earth and picks thorns laying them on top of the twigs. He flies back to earth and picks soft grass to cover the thorns. When this first layering is complete the male eagle runs back to earth and picks more thorns, lays them on the nest; runs back to get grass it on top of the thorns, then plucks his feathers to complete the nest. The thorns on the outside of the nest protect it from possible intruders. Both male and female eagles participate in raising the eagle family. She lays the eggs and protects them; he builds the nest and hunts. During the time of training the young ones to fly, the mother eagle throws the eaglets out of the nest. Because they are scared, they jump into the nest again. Next, she throws them out and then takes off the soft layers of the nest, leaving the thorns bare When the scared eaglets again jump into the nest, they are pricked by thorns. Shrieking and bleeding they jump out again this time wondering why the mother and father who love them so much are torturing them. Next, mother eagle pushes them off the cliff into the air. As they shriek in fear, father eagle flies out and catches them up on his back before they fall and brings them back to the cliff. This goes on for sometime until they start flapping their wings. They get excited at this newfound knowledge that they can fly. The preparation of the nest teaches us to prepare for changes; The preparation for the family teaches us that active participation of both partners leads to success; The being pricked by the thorns tells us that sometimes being too comfortable where we are may result into our not experiencing life, not progressing and not learning at all. The thorns of life come to teach us that we need to grow, get out of the nest and live on. We may not know it but the seemingly comfortable and safe haven may have thorns. The people who love us do not let us languish in sloth but push us hard to grow and prosper. Even in their seemingly bad actions they have good intentions for us.
PRINCIPLE 7
When an Eagle grows old, his feathers become weak and cannot take him as fast as he should. When he feels weak and about to die, he retires to a place far away in the rocks. While there, he plucks out every feather on his body until he is completely bare. He stays in this hiding place until he has grown new feathers, then he can come out. We occasionally need to shed off old habits & items that burden us without adding to our lives.
