What is the vision of pigeons: a description of the structure of the eye and how birds see, features

Doves have existed alongside humans for many centuries. Various species of these birds inhabit all continents except Antarctica. However, many people know very little about these birds, for example, not everyone has seen the chicks of this familiar bird, they do not know what kind of vision a dove has and what color dove eyes are. There is a chance to get answers to questions about their vision and eye structure today.

The structure of the eye

These birds have excellent sharp eyesight. It helps birds to rise to great heights, perform complex somersaults in the air.Birds with poor eyesight cannot do this. When buying thoroughbred pigeons, in addition to the exterior, they pay attention to the hearing, vision, and flight abilities of birds. These parameters are also important when pairing, because the chicks inherit the diseases of their parents and their best qualities. The pigment in the iris determines the color of the bird's eyes.

The large eyes of pigeons are located closer to the beak, on the sides of the head. They are round, set deep and protected by the third eyelid. When the pigeon falls asleep, it closes the eye and protects it from the ingress of litter and dust. The eyelid is mobile, located from the inner corner of the eye, it periodically extends, wetting the eyeball.

In some breeds of birds around the eye there is a warty layer that serves as additional protection. In fighting breeds, large outgrowths above the eyes serve as additional protection against dirt and small insects.

The recess in the eye, which contains many light-sensitive cells, works like a telescope, so pigeons can clearly see objects at a distance of more than 3 kilometers.

When buying, the eyes of birds are examined under a bright lamp, the light does not harm the pigeon, its eyes quickly adapt to the brightest sunlight.

They consist of several important elements:

1. Their pupil is small and round, the light is used to check the work of the sphincter muscle responsible for the expansion and contraction of the pupil.
2. The pupil is in the so-called adaptation circle, the darker this part of the pigeon's eye, the better the bird flies.
3. Next comes the circle of correlation, it is pink in chicks, darkens with age, the darker the shade, the higher the mental, flight and adaptive abilities.
4. The iris can have different shades. From honey or amber to cherry color. Sometimes the bird loses the pigment of the iris, then the eyes become gray or pearly.

A pigeon can perceive 75 frames per minute, a human only 24.

How do doves see?

Visual acuity in birds is much higher than in humans, their eye perceives more shades, they see in the ultraviolet spectrum. At dusk, the pigeon's vision is worse than in bright light. In their perception, objects move slower than for a person. Pigeon eyes have a 360 degree viewing angle. If it were not for the slow reaction, due to the specific perception, the bird would not be surprised or caught.

What color are birds' eyes?

Doves are born with blue eyes. As you grow older, the color of the iris changes. It is inherited from parents and depends on the amount of iris pigment and the condition of the blood vessels of the eye. If the amount of pigment prevails, the pigeon's eyes will be yellow, pigment and dilated vessels in equal proportions will give an orange tint, a small amount of pigment and dilated capillaries will provide a red color to the iris.

Feathers can have eyes of different shades. Pedigree individuals with heterochromia are culled.

Surprisingly, there is no comprehensive information about how doves see, and other types of birds, as well as animals and insects. Scientists keep making discoveries. And doves are a symbol of peace and love, delight people with the beauty of flight and remain familiar strangers living nearby.
