Why is it said that eagles are clairvoyants? Why do eagles have so good eyesight?

The eagle can accurately distinguish the animals on the ground at an altitude of several thousand meters, and even snakes and voles cannot escape its eyes. This is due to the unique eye structure of eagles. On the retina in each human eye, there is a groove called **concave, but there are two **concave in the eagle's eye.

These two concaves have different functions, one of them is specifically used to look ahead, and the other is specifically used to look to the side. In this way, the eagle has a much wider visual range and can take into account both the front and the side. In addition to this, there are six or seven times more cells in each fovea of the eagle for seeing than we humans do.

Therefore, the eagle's eyes not only see farther than other animals, but also see more clearly, and people give it the nickname one"Clairvoyance".Eagles are the tallest among birds. Not only does it fly high, but it flies fast.

High in the air, the eagle is still able to clearly see the small animals on the ground. We can't help but ask, why is its eyesight so good? In fact, this is due to the unique eye structure of eagles.

In each human eye, there is a groove on the retina, called the ** concave, but in the eagle's eye there are two.

In this way, the eagle has a much wider visual range and can take into account both the front and the side.

In addition, the eagle has six or seven times more cells than us humans in the fovea used to see. The eagle's eyes not only see farther than other animals, but also see more clearly. The eagle can accurately distinguish animals on the ground at an altitude of several kilometers, and even snakes and voles cannot escape its eyes.

Eagles are a carnivorous group that usually forages in canyons. The difference between eagles and birds in general is that eagles belong to the category of birds of prey, and birds in general belong to the omnivorous category. Eagles are fierce and carnivorous, feeding on birds, rats, and other small animals; Some species prefer to eat carcasses, such as vultures.

The wings are well developed, good at flying, and generally active during the day. It mostly inhabits mountain forests or plains, such as goshawks, sparrowhawks (harriers), etc. The eagle eagle is stout, with long and broad wings and tail feathers, and is slow to flap its wings, often hovering and soaring at high altitudes near mountainous areas, and can prey on large mammals such as hares, snakes and other small animals, young animals, and rodents.

The common species in our country are golden eagles and black eagles. The eagle family is a very complex family, and the birds of prey that we are familiar with such as eagles, eagles, harriers, buzzards, and Old World vultures are all members of the eagle family. The members of the eagle family vary in size and habits, from the largest and most ferocious birds of prey to small birds of prey, some eat scavengers, such as many vultures, some eat birds, such as sparrowhawks, some eat beasts, such as horned eagles, some eat fish, such as fishing eagles, some eat reptiles, such as snake eagles, some eat insects, such as bee eagles, and some adapt to special things, such as palm vultures, which eat fruits, and snail kites, which eat snails.

The eagle family can be further divided into 9 subfamilies, with 64 genera and 209 species, of which there are kite, eagle, eagle, buzzard and vulture in China, a total of 20 genera and 46 species, which are not extensive. <>

Falconers take advantage of the habit of the eagle to land on a large tree with a wide field of vision to find its prey first, and rush down to catch it once it finds its target. When hunting, the hunter and the hound help to alarm the prey, while the prey is panicked, the falcon strikes and captures the prey, at this time the hunter must arrive in time, take the prey, and feed the falcon as a reward, otherwise, the prey will become the goshawk's food. In many countries around the world, the peregrine falcon is also commonly used as a falcon.

In the Middle Ages, in England, only nobles above the earl level had the right to own peregrine falcons, and the average poor people could only tame other eagles. In ancient China, the falcon was called the eagle, which means a flying bird. Peregrine falcons fly fast, reaching up to 360 kilometers per hour when catching prey.

Peregrine falcons feed mainly on birds, and most of them hunt in the air. They catch up with their prey at high speed, stretching out their claws and striking their prey. The prey is injured and falls straight to the ground, and sometimes the peregrine falcon intercepts the prey in the air without waiting for it to land.

However, sometimes peregrine falcons also miss and cannot hit their prey in one fell swoop. In this case, the peregrine falcon never gives up its prey, and it will rise to the air again to attack until it captures its prey. As a result, peregrine falcons are widely appreciated by falconers.

The eagle is mostly active during the day, and even if it soars at an altitude of more than a kilometer, it can see the prey on the ground clearly.

It is difficult for the human eye to see small insects from 20 meters away, but it is very easy for eagles, who can see small insects even 100 meters away.

The eagles' eyesight is so sharp thanks to their well-developed visual system.

There are a lot of cone cells in the retina of the eagle eye, about 1.5 million per cubic centimeter, but there are only 200,000 in the human eye, which means that the eagle's vision is 8 times sharper than the human eye.

When there are locusts in the distance, the human eye can only see a very blurry image, but ordinary birds can see clearly. This is because there is one more ** fovee on the retina of birds than humans, which is specially used to look at objects on the side and widen the field of vision.

In addition, birds have protruding comb-like organs in the retina of the eye, and the function of this comb is to make the image that enters the eye clear.

The eyesight of human eyes cannot be compared with that of eagles, and even compared with ordinary birds, they will sigh to themselves. The eagle has these characteristics because of its eyes, and although it does not use a telescope, it can really be called clairvoyant! Eagle.

The eagle's eyes are very wide-ranging, it is both farsighted and short-sighted, and its sharpness in observing objects is among the best among birds. The eagle's eyes have two **concave surfaces, and the density of cones is about six or seven times that of the human eye, so the eagle's vision is much more sensitive than that of a human. When the eagle looks down on the ground at an altitude of more than 2,000 meters, it can spot small animals from many moving scenes, and can constantly adjust the viewing distance and focus to see more details and help it catch its prey accurately.

Eagles can see their prey from afar, and some animals have even better eyesight. One of the easiest ways to improve human vision is to expand the range of light frequencies we can see, so that opsins are adjusted to a wavelength that you want to perceive. Eagles can see their prey at a distance because their conus cell photoreceptors are tightly packed on the retina.

One way to improve the clarity of the human eye is to stuff the retina with more conus cells. Although this will improve our vision, it can cause discomfort to our eyes, so be careful.

Eagles generally refer to various birds of the genus Eagles. There are 59 species of eagles in the world, and scientists classify them into four major groups. In general, eagles within the same group are similar, for example:

Similar body shapes or foods that are similar; However, there are obvious differences between eagles of the same species, such as body size, wing color and structure. Eagles are found on every continent on Earth except Antarctica, and can be found in deserts, jungles, marshes, woods, mountains, and seashores.

All eagles hunt during the day and rest at night. Wild eagles live for about 20 years, and raised eagles can live for 40 years.

Actually, I don't know if eagles can see prey from more than 10 kilometers away, but from the cartoon Sheriff Bresta we watched as a child, we know that eagles must have the best eyesight in the animal kingdom.

As far as I know, there are two main reasons why eagles have good eyesight:

First, the structure of the visual system of the eagle eye is very special, the most obvious is that the eagle eye has two ** concaves. Here I will explain to you what is **concave. It is the area of the retina where vision is most acute.

Color discrimination, resolution, etc., all depend on it. We humans have a small yellow area in our eyes, which is what we commonly call the macula. In the macular area, there is a depression, which is the depression.

Because of this, the eagle eye with two ** concaves is far superior to us humans in terms of color discrimination and resolution. I won't elaborate on how the two ** concaves work, because it's too academic and not easy to understand. If you are interested, you can read ophthalmology-related books to understand.

The unique structure of the eagle eye forms a special visual system, similar to the principle of a telescope, which can magnify objects many times.

Because eagles never play with their phones.
