The feathers around the eyes of the owl are radiant, and the fine feathers are arranged to form a face, which is shaped like a cat, so it is named the owl.

Its feathers are mostly brown, scattered with fine spots, dense and soft, and silent when flying.

The female owl is generally larger than the male.

The head is large and wide, the mouth is short, the side is flat and strong, the apex is crooked, the base of the mouth has no wax film.

And is mostly covered by hard feathers.

Like many carnivores, owls have eyes directly in front of their faces, giving them excellent depth perception during hunting, especially in dim light.

Owls have very large pupils and can absorb more light at night.

Most animals have two types of sensory cells in the retina at the bottom of the eye, one is the rod cell, and the other is the cone cell.

The rod cell is young to the weak light (can feel a photon), but can only distinguish between light and dark, but can not distinguish the details and color of the object.

The cone cell, which can sense strong light and color, has a strong ability to distinguish the details and color of the object.

On the other hand, owls have only rod cells and no cones in their retina.

Therefore, owls have good puberty to low light and are suitable for nocturnal activities.

In addition, because the owl's eyes are distributed in front of the plate, and its visual range has overlapping areas, owls can see "three-dimensional" objects, which is helpful for them to accurately judge the distance of their prey and catch them accurately.

Although the owl's eyes are young in low light at night, the range of sight is limited because both eyes face forward and cannot be rotated in the eye socket.

But owls also have a solution to this problem.

Owls have a special cervical vertebra structure so that the neck can rotate very flexibly, the range of movement of the head can be as high as 270 °, and their faces can even turn back.

Therefore, owls have a very wide range of observation, which is good for catching prey and avoiding enemies.

Owls are mainly active between dusk and dawn. When they fly, the flight is silent.

These big birds sometimes even soar or glide over long distances. Eurasian eagle owls usually live alone or in pairs in trees or rock crevices during the day.

One of the unique features of Eurasian eagle owls is that each adult bird has a different way of sounding.

This means that you can determine which owl you hear by listening to its voice.

Eurasian eagle owls can be found in a variety of habitats, from colder forests to warm deserts.

But they prefer rocky landscapes. You can find them in Europe, the Middle East and northern Asia.
