It is enough to look at the scientific research done to understand that birds are living things that should not be taken as such.
Human beings may lose their way at a time when they do not know, but birds are never. Even in the city we live in, sometimes we feel like we lost our way. We may not know where we are in the world when our sense of direction is not working. This is natural, because we do not have the ability to sense the direction of the magnetic field; there are birds.
It is a scientific secret that the birds are using this feature, which we will call a kind of magnetic compass. Although it was suspected for a long time that a structure in the crag was suspected, it soon became apparent that the situation was not so. This ability is not cognitively governed, but an ability to allow birds to see magnetic fields. So they do not feel it, they see it directly. According to scientists, there is a very special protein behind this.
There are two different bird species called american pomegranate bulbula and zebra ispinozu. In the eyes of these birds, there is a protein called Cry4 that is part of the sense of sight. Cry4 is also present in plants and in different animal species. This protein is sensitive to blue light; is playing a role in controlling the "circadian" processes known as the whole of the biochemical and psychological behavior of plants, animals, fungi and cyanobacteria in the 24-hour period.
It is already known that birds can detect magnetic fields when they are exposed to light in a certain wavelength. Biological structures cause them to be sensitive to blue light. In the recent studies, it is noted that this process is related to the images.
Researchers from the University of Lund in Sweden zebra finches, researchers from Carl von Ossietzky University in Germany have confirmed the visual relationship with their work on the pomegranate narcissus
