What kind of bird has the best eyesight? How far can you see?

Birds have two to three times the eyesight of humans.

Among the sensory organs of birds, the most developed are the visual organs, which play an important role when flying through the air, while the olfactory organs are underdeveloped. The bird's eye relies on the well-developed ciliary muscles to quickly adjust its vision, changing from farsightedness to nearsightedness.

When the bird flies through the trees, it never touches the branches; Or when diving from a high altitude to the ground to forage, it can also be adjusted from "farsighted" to "short-sighted" in an instant.

The instantaneous membrane of the bird's eye is well developed, which covers the eyeball and plays a protective role when flying. Also, the cerebral cortex of birds.

Not well developed, cerebellum.

It is well developed, which is associated with the coordination and balance of the bird's flight movement. The midbrain forms a pair of well-developed optic lobes on the back.

1. Kiwi birds in New Zealand have the worst eyesight.

2. Wingless birds (scientific name: apterygidae): belonging to the bird class wingless birds, the family has only 1 genus and 5 species, commonly known as "kiwi", distributed in New Zealand, their chirps are very sharp, and they sound particularly like "kiwi" (several-dimensional), so they are called kiwi by the local aborigines.

3. The appearance and habits of kiwi birds.

The kiwi, the most primitive of the sandpiper birds, is about the same size as the common big rooster, with a body length of about 25 35 centimeters and a weight of about kilograms. Their coat color is mainly yellowish-brown with dark gray and pale transverse spots, and the belly coat is lighter with black-brown stripes, the kiwi's feathers are fluffy, fine and soft, plus its small and stubby stature makes it look like a hairy ball, so it is very cute, in addition, their vestigial wings are covered with feathers, they look like they have no wings, no tail feathers, so they cannot fly like other birds, however, they have stubby and strong legs, are good at running, and can reach speeds of up to 10 miles per hour.

4. Diurnal and nocturnal.

Kiwi birds have poor eyesight, they do not leave their burrows during the day, except in dangerous situations, this is because their eyes cannot be exposed to sunlight, otherwise they will go blind.

5. Lingyu code sensitive sense of smell.

The wings are small, tend to be vestigial, and hide under the body feathers. The legs are thick and powerful, the tail is completely gone, the eyes are small, the ear holes are large, the kiwi bird has a long and curved beak, the nostrils are long at the tip of the beak, the sense of smell is extremely sensitive, and they can search for prey on the ground, they can smell the insects at a depth of more than ten centimeters underground, and then dig out the insects with their claws or mouths to eat them, the food of the kiwi bird is mainly insects, snails, spiders and shrimps, and it can also eat small lizards and mice.

Among birds, the eagle is the most praised for its eyesight, which under normal conditions can reach a range of up to 36 km. In addition to its wide field of vision, the eagle's eye is also extremely keen and can accurately identify objects at high altitudes, so the word "eagle eye" is often used to describe a person's sharp gaze.

The eagle is a majestic bird with a fierce temperament and is one of the top 10 most dangerous birds in the world. Hawks generally inhabit canyons and woodlands and prey on small mammals, reptiles and other birds. With a pair of powerful claws, they can hold their prey firmly, and their powerful hooked beak allows them to tear through the flesh of their prey with ease.

The eagle's eyesight is famous in the animal kingdom, it is a well-known clairvoyant, even if it soars at an altitude of more than a kilometer, it can find prey on the ground. Its eyes not only see far, but also see very clearly, can accurately distinguish the species of prey, snakes, rabbits, voles, etc. can not escape its eyes, the sharpness of observing objects is among the best among birds.

The reason why the eagle has such excellent vision is closely related to its unique eye structure. Unlike humans, who have only one fovea on the retina of each eye, the eagle has two grooves, the positive fovea and the lateral fovea. One is used to receive the image of the object in the front field of view, and the other is to receive the image of the object directly in front of it, so the eagle's field of vision is very wide.

At the same time, the eagle eye has a large pupil and a special structure in the eye that weakens the scattered light, which can make the vision clearer.

Among the various sensory organs of birds, the visual organs (eyes) are relatively sensitive, which is related to the need for birds to see their surroundings clearly when flying. Different birds have different eyesight, which is related to the size of the bird, its range of activities, feeding habits, etc. Birds of prey such as the battalion have very good eyesight, and can see the activities of pikas and other birds on the ground at an altitude of about 1 km, and quickly swoop down to hunt.

Owls have a more sensitive sense of hearing among birds, as they often come out at night and rely on echolocation to sense their surroundings and hunt.

Birds see things differently than people, and many birds, such as pigeons, can distinguish millions of different colors, and they are considered to be the best animals on the planet at distinguishing colors. Birds have far more conus cells in their eyes than humans, suggesting that they can see at least five spectral bands.

Yes, birds of prey have many times the eyesight of humans. Think about it.

When the eagle flies very high, you can see the activities of small animals on the ground, swooping down from the sky to hunt...

The average bird also has a very good eyesight much better than mammals.

But birds' sense of hearing is not as good as that of mammals, and their sense of smell is not as good as that of mammals, and there is a telescope in the Hangzhou Xixi Wetland Nature Museum, which can imitate birds to see things.

It's good, but some of them look like blind people.
