The owl's eyeballs are tube-shaped, and some have described the owl's eyes as a microscopic telescope. In the retina of owl eyes, there are extremely abundant columnar cells. Styloid cells can sense light signals from the outside world, so the owl's eyes should be able to perceive very faint light.
If we compare a bird's eye to a camera, the eyes of most birds suitable for daytime activities are small-aperture standard lenses, and the owl's eyes are large-aperture, long-focal length telescopic lenses. Therefore, for a long time, it was believed that owls flew and hunted in the dark by sight. However, if an owl is measured by the visual sensory system that ordinary birds have, then to achieve the vision of an owl, its entire brain must be composed of optic nerves!
The owl's sense of hearing is very sensitive, and in the dark environment where the fingers are not visible, the sense of hearing plays a major role in positioning. The owl's left and right ears are asymmetrical, the left ear canal is significantly wider than the right ear canal, and the left ear has a well-developed ear drum. Most owls also have a cluster of ear feathers, which form a human-like pinna.
The auditory nerve of an owl is well developed, and a barn owl weighing only 300 grams has about 10,000 auditory nerve cells, while a crow weighing about 600 grams has only 10,000 cells. In addition, the owl's face is densely packed with raw hard feathers to form a noodle plate, and this noodle plate is a good sonic collector. The owl's large head allows for a greater distance between the ears, which enhances the resolution of sound waves.
When an owl searches for prey in the dark, its first response to sound is to turn its head, just as we listen intently to a tiny noise. But the owl doesn't really listen, it turns its head to make a difference in the time it takes for sound waves to reach the left and right ears. When this time difference increases to more than 30 microseconds, the owl can accurately distinguish the orientation of the sound source.
Once the owl has judged the direction of its prey, it quickly strikes. The owl's feathers are very soft, and the wing feathers have velvety dense down, so the frequency of the sound waves produced by the owl when flying is less than 1 kHz, while the ears of the average mammal do not feel the low frequency. Such a silent sortie makes the owl's attack more "blitzkrieg" effect.

The owl's living habits are related to her food schedule, the owl's attention food is voles, and voles rest during the day and come out at night, and the owl's physiological structure is also suitable for coming out at night. The two eyes are similar to a cat's eye, and the owl has strong talons that make it easy to catch voles. It is a typical nocturnal animal.
The eyes of the head eagle are round and large, which is very distinctive. Its eye structure is different from that of ordinary animals, the light during the day is too strong, and its eyesight is particularly poor, so the owl always sleeps during the day and only comes out at night Because it has a lot of photoreceptor cells in its eyes, it can see most clearly in the weak light at night, just like humans use infrared telescopes The owl is a carnivorous bird, squirrels, voles, rabbits, frogs and snakes are its prey objects, the owl's powerful beak and claws are particularly powerful, and none of these small animals is its opponent. In addition, the owl has very large ear holes, very good hearing, it can hear very small sounds at night, its wings are big and powerful, it flies without any sound, and it is difficult to escape once the prey is discovered, with so many conditions, the owl can certainly hunt at night.

Are owl eyes really only visible at night? Scientists tell us that this is not the case, and that if you look closely at owls and other birds, you will find that there is a big difference, that is, owls have much larger eyes than other birds, and both eyes are facing forward, and because the owl's eyes are large, it can easily sense even a little lightd, for example, even a faint starlight or moonlight will feel very bright for an owl. So the owl can see clearly during the day, but because the light is too bright during the day, the owl has to hide, and at night, it sees very clearly.
The owl has a keen eye. In the dark of night, visibility is more than a hundred times higher than that of people. Unlike other birds, owl eggs hatch one by one, and after the first egg is laid, it begins to hatch.
Owls are homeothermic animals. There is a kind of owl in Africa, the eyes can emit light like a flashlight, and the brightness can be adjusted, the local indigenous people use the owl to hunt, what is even more amazing is that the light emitted by the owl's eyes shines on the animal's eyes, and the animal is unaware. According to the natives of Africa, the light from the owl's eyes can keep the prey still.
It is not known if this is the case for owls elsewhere.

It can see, but in the presence of bright light during the day, it cannot see normally.
Owl. It is a typical nocturnal bird with a very sensitive optic nerve.
Such eye structures do not appear to adapt to the intense light of the day, and although they can see during the day, the dazzling light makes their vision blurred.
Reasons why owls can't see clearly during the day:Owls are typically nocturnal birds, with very sensitive optic nerves and ultraviolet rays during the day.
It can cause damage to its eyes.
The owl's eyeball is tubular and retinatal.
There is an extremely abundant rod cell, which is responsible for seeing in low light and has a weak ability to distinguish colors.
So in the case of bright light during the day, the owl cannot see normally, and at night it has better eyesight than a human.

Unseen.
Owls have very good eyesight in the dark, and they are basically invisible during the day, and their eyes are a telescopic lens, which can only receive faint light, but when hunting at night, they are very accurate.
Owl habits.
Owls mostly live in trees, and some species live among rocks and meadows.
The feathers around the owl's eyes are radial, and the arrangement of the fine feathers forms a face plate, which resembles a cat, hence the name owl. Its feathers are mostly brown, scattered with fine spots, dense and fluffy, and it is silent when it flies.
Females of owls are generally larger than males. The head is large and broad, the beak is short, the sides are flat and strong, the apex is hooked, the base of the beak is not waxy, and it is mostly covered by hard feathers. Like many carnivores, owls' eyes are located directly in front of their faces, which gives them excellent depth perception during hunting, especially in dimly lit environments.

In fact, it is not necessarily limited to the night, and there is also the possibility of activity during the day, but there are more mice coming out at night, so the activity is more frequent at night, and it usually comes out after dark at about five or six o'clock.
-
There are two types of optic cells, namely rod cells and vertebral cells. Rod cell negative.
It is responsible for seeing in low light, while vertebral cells are responsible for seeing in bright light. Rod cells have weak color resolution, and vertebral cells have strong color resolution. That's why we often can't tell the difference between colors when we see things at night or in dimly lit places.
Rod cells have weak color resolution, and vertebral cells have strong color resolution. That's why we often can't tell the difference between colors when we see things at night or in dimly lit places.
The owl's eyes are full of rod cells, and basically do not contain vertebral cells, so in the case of bright light during the day, it cannot see normally, and at night its vision is n times better than that of humans.
It should be correct that owls are unable to see in bright light.

It should be correct that owls are unable to see in bright light.
The owl only has rod cells, basically no cones, so it has a keen vision at night, and it can't see anything clearly during the day, and it can't feel color, so it's a complete color blindness. In contrast to owls, pigeons and chickens have only cones and no rods, and are born with night blindness.
Why can't pigeons and chickens see at night? It is because it is blind and manifests itself in the dark or in places with low light. The reason is that its eyes cannot produce rhodopsin.

Owls can't see when their eyes are bright, but they can form a focal length and see things when they're dark.

Owls are typical nocturnal birds. Because at night his vision is better and he can see more clearly. During the day, strong ultraviolet rays can cause damage to his eyes, and it is not that he cannot see things during the day, so he cannot see clearly due to the light.

-
The owl is a nocturnal animal, the owl can not see things during the day, and at night, under dark conditions, it can only see things in Yundong, because its eyes are caused by a very special eye and small joint.
-
Because his eyes really can't see bright light.
-
It's not that he can't really see things during the day, he can see during the day, it's just that he doesn't know very well, and the owl is generally nocturnal, so he basically doesn't come out during the day, leading to the general belief that he can't see things during the day.
-
Because the ultraviolet rays during the day can cause damage to its eyes. So during the day it is rarely active. On the contrary, the physiology of owls has developed to be suitable for catching food at night.
-
Because the owl is a nocturnal bird, its optic nerve is very sensitive, and ultraviolet rays can cause damage to its eyes during the day.
-
It's not that an owl can't see during the day, but that his eyes are sensitive to daytime sunlight! It will have some impact on your eyesight!
-
Because the owl needs to avoid predators, and it is a nocturnal animal, the owl has very good eyesight, so it can see clearly.

When you see an owl, there's no good or bad thing about it. In fact, seeing an owl is no different from seeing other birds, and nothing bad will happen. The key is not to believe such false superstitious claims.
There are common sayings such as "night owls enter the house, nothing to do", "not afraid of night owls calling, afraid of night owls laughing", often regard owls as "ominous birds", called soul birds, mourning birds, etc., and in ancient books, it is also called strange owls, ghost cars, ghosts or displacement, as a symbol of bad luck and death.
The reason for these perceptions is mainly due to the fact that owls, due to their keen sense of smell, can smell the scents of sick people, and can laugh, and in many places it is indeed not superstitious to die within a few days of hearing the owl's call, so owls are called mourning birds.
Is it good to see owls during the day.

Good or bad. There is nothing bad about it.
It's good or bad to see during the day.
The owl is a beneficial bird, so we should be kind to this kind of bird, all say that the old cat comes into the house without anything, in fact, the old cat is to eliminate the pest, and when you see the old cat, you will catch it.
The habit of eating and not eating does not change! It doesn't swallow iron stuff either! Even if you eat an owl, you will spit out what he can't digest! Owls swallow food and spit out the bones and hairs of voles or other foreign objects that cannot be digested!
Eat, the owl's diet is mainly rodents, but it also eats insects, small birds, lizards, fish, snakes and other animals. >>>More
Because of the owl heard.
Calling, it means that someone is about to die, so the old people think that the owl is unlucky. There is also the fact that owls have completely different habits from humans, and owls are nocturnal animals. >>>More
It's not a cry, it's just a human-like cry that mistakes an owl for a cry, but it's actually a cry. >>>More
