Is an owl a cat or an eagle? Why does it like to travel at night?

The owl is neither a cat nor an eagle, it is a special type of bird. The owl's eyes can see at night and have a vision dozens of times higher than that of humans. Traveling at night is good for hunting.

The owl is a type of eagle that likes to travel at night because it has a habit of walking diurnal, resting during the day and hunting at night!

It's an eagle, because owls' eye vision only comes into play at night and then hunts, and daytime cathead eagles have poor eyesight and are basically inactive.

Because the owl needs to avoid predators, and it is a nocturnal animal, the owl has very good eyesight, so it can see clearly.

There are no absolutes. Daytime cathead eagles will also call. It's just that it's called less. Most are called at night. Because during the day they are mostly resting. Only at night when there is a lot of activity, it makes a whining sound.

That's why we often hear owls whining at night. This cry also has the meaning of calling for companions.

There is no foreshadowing, it's just folklore. If an owl accidentally flies into the house, be sure to open the window and let the owl fly out.

When an owl flies into your home, it means that the owl recognizes you and thinks you are not a threat to it. Both animals and humans have a set of hazard recognition mindsets. If people realize that a certain place threatens their safety, they will subconsciously avoid it and not approach it, and the same is true for animals.

However, if the owl is not afraid of your home, it means that your family has some kind of factor to make it understand that your house does not pose a danger to it, but feels safe with it, so it flies into your house.

Animals can't speak, but they have spirits.

There is no foreshadowing, the owl is a beneficial bird, and the folk rumor that the owl is unlucky, indicating that the dead will die and the like are feudal superstitions, just like looking at people, we can't look at anything by their appearance.

In fact, the little owl is particularly cute.

1. Mainly because owls are typical nocturnal birds. UV rays during the day can cause a lot of damage to its eyes. Physiologically, the owl's eyeballs are tubular shaped. Therefore, the owl's eyes should be able to perceive very faint light.

2. The owl's sense of hearing is very sensitive, and its hearing plays a major role in positioning. The left and right ears of the owl are asymmetrical, the left ear canal is 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.

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 large distance between the ears, which can be used to enhance the resolution of sound waves.

3. When an owl searches for prey in the dark, its first reaction is to turn its head, just as we listen intently when we listen to the slightest noise. But the cat's function of turning its head is to make a difference in the time it takes for sound waves to reach the left and right ears. Once the owl has judged the direction of its prey, it quickly strikes.

Such a silent attack makes the owl's attack more effective in rapid predation.

4. The owl can constantly adjust the direction of the attack according to the sound generated by the movement of the prey, and finally come out with its claws, which is effective in one fell swoop. Of course, the owl's role of sight and hearing in predation is complementary.

Because the owl's optic nerve is very sensitive, the ultraviolet rays are too strong during the day and the rock fingers will stab its teasing eyes, and the light is relatively weak and quiet at night, and the owl hunts by hearing at night.

Owls have strong eyesight. The eyes of owls have a special eye structure that is different from a variety of birds that are generally active during the day. On the owl's retina, there are two types of sensory cells – rods and cones.

Rods are very sensitive to light; Cone cells have the ability to sense color. So, whenever night falls or the morning light fades, it is able to see everything we can see, so that it can hunt and avoid enemies.

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 thick beam ear drum. Owls are also superior at judging the source of sound.

When the sound comes, the ear close to the source receives it stronger. This extremely small difference in volume allows the owl to determine the location of the sound source.

<> "Why do owls like to be active at night?"

Why do owls move at night? Folklore and fables give several versions of the answer to this question, one of which is that owls only dare to move at night because they think they are ugly; In another or Min Bang version, the owl is selfish and offends all the birds, so he does not dare to come out during the day. So, what is the answer that science has come up with?

The owl is a common name for birds of the order Ospreidae and Grass Osprey. The vast majority of owls are nocturnal, with some species only active at night and able to hunt in near-total darkness, such as barns and ghosts. There are also some that are active in the morning and dusk, and of course there are a few that are diurnal.

Owls are carnivorous birds, and the main reason why they are active at night is because their prey comes out at night. That is, it is the law of activity of the prey that determines the law of activity of the owl.

In order to adapt to life in the dark, the body structure of the owl has undergone different degrees of specialization. We know that there are rods and cones on the retina that are responsible for sensitizing light to external objects, the former is highly sensitive to light, but cannot distinguish colors, and the resolution of details is also poor; The latter is less sensitive to light, but can distinguish colors and can also distinguish details. During the day, when there is plenty of light, it is mainly the cones that are active; At night, when the light is dim, it is up to the rods to distinguish it.

In order to be nocturnal, the photoreceptor cells of owls are almost all rods, so that they can fly freely at night and cannot see clearly during the day. In addition, a pair of large ear holes behind their eyes are also secret**, with that special noodle plate is more conducive to collecting sound waves, and the owl has a special structure on the outside of its flight feathers, which does not make a sound when flying, and can quietly approach the prey, which also greatly increases the probability of success of its nocturnal predation.
