How can homing pigeon eyes tell good from bad?

Pigeons have eyes of various colors, commonly known as eye sand. Ocular sand is composed of many fundus blood vessels. Color is produced because there are 400 million photosensitive cells in pigeon eyes, which are red sensitive pigment, blue sensitive pigment, Huang Min pigment and Bai Min pigment. So pigeon eyes are divided into three categories: peach blossom sand, chicken yellow sand and cow sand. Some people think that trachoma is easy to fly on cloudy days, yellow eyes are easy to fly on sunny days, and bull eyes are easy to plant. But pigeons with trachoma of all colors can get good results in all kinds of competitions.

(2) Pigeon eyes and homing

Whether there is a close relationship between pigeons' homing and their eyes is a controversial issue. Now many people have pointed out (or even concluded) that the strange phenomenon in a pigeon's eyes is a rare good pigeon. Although some examples are pointed out to prove it, I think it can only explain one aspect and is not convincing. Indeed, most homing or award-winning pigeon eye sand has the characteristics of uniform sand, bright color and distinct layers, especially in the ultra-long-distance pigeon flock, the highly evolved pigeon eye is even more unusual. Some people say that homing pigeons fly by the electric friction of their eyes. We can usually observe that the flying height of passing homing pigeons is only tens of meters, and some people still blindfold the pigeons and let them fly home. It shows that pigeon eyes did not play a big role in flight.

Whether the eye-to-eye flap of pigeons is related to homing remains to be further explored by experts.

(3) Vision

Observing the pigeon's eyes with naked eyes, you will find that there are rings of various colors around the pupil, which is the eye mark. In the study of 53,000 excellent homing pigeons, Mr. Bishop of Wei Qiao divided them into 10 cognitive formulas. He said in his monograph: Eye marks can predict the possible ability of a racing pigeon. As far as I know, there is no other way to provide a correct identification method except eye marks. For a long time, everyone has been in a state of doubt about the eye pattern theory. What can eye lines tell? I don't think anyone can answer for sure at present. In my opinion, all kinds of eye marks can cultivate excellent homing pigeons. What are eye lines? According to relevant data, the eye marker is composed of tiny phosphorus sheets, which is used to adjust the position of pupils, regardless of the quality of homing pigeons. Therefore, when we choose pigeons, watch pigeons and evaluate pigeons, we should focus on competition results and pedigree. However, many pigeon fanciers have always believed in the theory of bibliography, which is the core of breeding and has achieved excellent results. Perhaps this is because individuals have different views on this issue.

(4) Internal buckle

It is difficult for naked eyes to see the shape of the inner buckle clearly, and it can only be seen clearly with a magnifying glass more than ten times in sufficient light. The inner buttons are all around the pupil, but the inner buttons are inside the pupil and the eyes are outside the pupil. The structure of pigeon eye can be divided into external sand, internal sand, eye sand, internal buckle and pupil from outside to inside, so it must be clearly distinguished. All kinds of colors and shapes are deducted from the inside line, most of which are dark brown, and the shape is; Wave type, link type, sawtooth type, point type, hole type, semicircle type and full circle type. Birsu Darberg, an American expert, thinks that homing pigeons can be divided into breeding pigeons, racing pigeons and racing pigeons according to the internal buckle; According to the shape, breeding pigeons with different distances and speeds can also be distinguished from eliminated pigeons. The use of internal buckle has been proved to be effective by many pigeon fanciers, and I also believe that the role of internal buckle can not be ignored. But don't be blind.

(5) Broken pigeon eyes

After many excellent racing pigeons return to their nests, we can often see that their eye sofas have changed, and some pigeons will have black broken lines, which are called stone lines (Shandong pigeon friend Jin Fan talked about this issue in the third issue of 1999 "The King of Pigeons"). There is a yellow-eyed raindrop pigeon in my shed, which was presented by Chen Lei, an elite pigeon house in Zhengzhou. There are black fold lines on both sides of the eye sand. I thought pigeons were ill at first, but then I read that pigeons with this characteristic were all top grade, and there was a book that said they were pathological. With all kinds of doubts, I called my pigeon friend in Chen Lei. Sure enough, this pigeon friend has extraordinary knowledge. So this one ... >>
