Budgerigars are one of the most popular decorative birds in the world. It is known that the population of home-grown parrots exceeds wild several times.
Not surprisingly, the owners of these winged pets are wondering: how do budgerigars see and how far will they be able to examine in detail these or other objects.
A little bit about bird sight
Vision is the main receptor, thanks to which parrots are oriented in space. The main organ is large, compared with other sizes, eyes.
Thanks to this anatomy, birds can obtain large images on the retina and more clearly distinguish all the details.
The vascular membrane, consisting of the iris, sclera, which is the external connective tissue of the eye, the cornea, which carries the function of light refraction, the vitreous, eyelids, muscles and lacrimal glands form the system of the bird’s organs of vision.
The main “cable" is like the retina – the optic nerve connecting the eye with the brain.
Budgerigars sharpen the subject by changing the shape of the lens and at the same time moving it relative to the cornea.
The blinking membrane moves along the surface of the cornea, moistening it with secretions from the lacrimal canals, and at the same time cleanses it.
The eyes of these birds are located on the sides of the head, and, as mentioned above, occupy approximately 50% of the total head volume, while in humans this is only 5%. Nature made sure to empower them.
Thanks to this arrangement, budgies have an almost circular view and are unlikely to be caught by surprise. They see most of the environment even with one eye and evenly.
Budgerigars can also move their eyes independently of each other and focus them on different objects located at different distances. For example, these birds, like many other species of birds, can control food and a moving object behind the cage. But at the same time, spatial vision in parrots is limited.
Looking at the color of the parrots, it is easy to guess that their world is as colorful as the feathers. Their eyes perceive more colors than human ones. Unlike people who have three types of color-sensitive cells, budgies have 4.
The human brain absorbs red, green and blue, so that we can see millions of shades. In budgies, ultraviolet is also added to this spectrum.
Recent studies have shown that the eyes of your winged friends perceive fluorescent light. This ability helps to select a partner.
What can a parrot consider?
Unlike people who can perceive 15-24 frames per second, parrots see 150 frames. It is noteworthy that dogs see less than 10 frames per second, so if they watch TV, then for them it’s just an incomprehensible set of pictures.
For parrots, on the contrary, the speed of perception is higher, which means that they fix more details. Flying several circles in a small room, within 3-5 seconds the budgie can see where its cage is located, where there are still objects to sit on, where are the moving objects, and where is the treat.
Some more facts about the vision of parrots
Budgerigars are quite shy birds, so at first, until you have tamed a feathered friend, you should not look him in the eye. This behavior causes natural reflexes in him, and the bird will think that you are not a friend, but a predator. Therefore, it is better to look away for the first time, but at the same time gently talk to the chick.
If your bird is already tamed, then for them, on the contrary, eye contact with the owner is very important. Playing with her, you can look into the eyes, talk, stroke.
Budgerigars are usually bred at home and as a result of this evolution, they have completely lost their ability to see in the dark. These are day birds, so at night they prefer to sleep.
A sharply switched on light in the room, when the parrot is sleeping, can scare him, cause unnecessary stress for him. The best solution would be to make a little noise before turning on the light, or use a nightlight.
A little bit about lighting a room with a parrot
Recent studies have shown that ultraviolet light is necessary for these birds to determine their gender and form pairs.
At the same time, in urban apartments, especially in winter, quite often there is not enough sunlight. In poor lighting conditions, a parrot may be deficient in vitamins and reduce the quality of vision – the bird will see in a black and white spectrum.
Which of these problems is the most dangerous? Most likely, both. Since birds have hollow bones and vitamin D3 is vital for their proper growth. The parrot, deprived of ultraviolet light, does not see bright colors, which makes it lethargic and lethargic.
In such a situation, you need to use lamps with soft ultraviolet low-frequency light of class A and B, however, you need to choose them very carefully, since high-pressure discharge lamps, on the contrary, can cause the bird to feel unwell. Also, it is advisable to use lamps with timers so that the light mode is constant.
