Select individuals with developed minds and cultivate high-IQ groups in order to stabilize and improve competitive performance.

1. Pigeon eyes should not be used as the primary condition for the selection of racing pigeons.
There are many pigeon lovers in our country who use pigeon eyes as the primary condition for the selection of racing pigeons. I'm no exception. But through years of observation and practice, I have learned that pigeon eyes change with age; some characteristics do not appear until they are over 10 years old. If a pigeon is born and does not participate in the race, its eyes remain in the same state as adulthood and do not gradually age until after the prime of life. Brooding, poor nutrition, emotional effects, illness and lack of sunlight, exercise can also make changes in the eyes. Especially the pigeons that participate in the competition, their eyes change rapidly. The pigeon has been racing for two or three consecutive years since the age of one, and its eyes have evolved year by year in the direction of the racing type. If a pigeon only participates in the race and does not let it breed a large number of chicks, the eyes that were changed due to the race will return to their original state. The eyes of the winning pigeon are formed by a long period of strenuous exercise and high mental tension, and with the gradual deepening of frequent flights, it is absolutely different from a pigeon that has not been trained by racing. However, these acquired traits are not passed on to future generations. So it is not possible to find a pair of eyes like pigeons with many years of racing experience in pigeons under one year of age or in pigeons that have not participated in racing. The winning pigeon is the top of thousands or even tens of thousands of pigeons, and it is not of practical significance to use it as a criterion for selecting racing pigeons in their own shed. The pigeons chosen by the eye are not necessarily all right. When the young birds' eyes first see the signs, they are already seven or eight months old, and it is too wasteful to eliminate them at this time. With these points in mind, I do not think that pigeon eye should be the first condition for the selection of racing pigeons.
2. Why should the brain shell of the pigeon be used as the primary condition for the selection of racing pigeons?
Today's pigeons have a homing ability that far exceeds the daily activities of wild rock pigeons. So to reach such a level, the key is that human beings have changed their way of life, constantly strengthening training, use and long-term directional cultivation, prompting the various components of its organism to evolve in a direction conducive to competition. In particular, the exercise of the thinking system greatly improves its own quality and function, so that the instinct of homing can continue to develop.
Only the pigeons return from afar, along the way to "fight the sky", "fight the earth" and "fight the natural enemies", in the foraging, finding water and roosting, but also with the people who capture it, anytime and anywhere to make the correct assessment and countermeasures to the objective outside world. If there is no brain with a high IQ, once it encounters obstacles, there will be navigation errors, slow response, lax guard, lack of response and decline of will. The consequences of this are as light as trek and heavy as losing one's life. Many senior pigeons have a deep understanding of this. So in their writings they pointed out to us that "the head of the pigeon should be big and round". There are many pigeons who use the eyes of the pigeons as the first and main condition for the selection and selection of racing pigeons. However, in terms of the function of the part; the eye is only the first to receive external information, neither the part of comprehensive analysis and generalization of information, nor the part where decisions are made and orders are given later. The central nervous system is the central nervous system that makes decisions and gives orders, which plays the role of overcoming all difficulties and dominating "destiny" in the homecoming. The visual part only plays the role of observing and transmitting information from the outside world. Therefore, the eyes should not be used as the primary and main condition for the selection of racing pigeons, but the part that dominates the "fate", the head, should be used as the main condition for selection. In other words, can a pigeon return home victoriously? The most decisive thing is to rely on one's own wisdom and perseverance, not on the eyes.
Some people will ask, whether the mind is good or not, it is impossible to see what cannot be touched, how to grasp it? It is true that what is inside is invisible, but the mind is produced by matter (brain cells). In the same part of the same organism, the more cells there are, the greater the energy. Therefore, the quality of the site is first determined by the number of its cells. Therefore, any part that is more developed than the same kind must be better. This argument is in line with both the evolutionary view and the materialist dialectical view of "quantitative change to qualitative change". Therefore, the abundance of intrinsic material conditions must be manifested in the appearance (brain shell). This becomes something that can be touched.
Through decades of practice and observation, I have found that many excellent pigeons have a good head shape – a brain shell.
3. The shape and capacity of the pigeon's brain shell.
In order to facilitate the discussion and comparison, the shape of the pigeon's brain shell is roughly divided into 5 categories and 8 types.
Category 1: Slope shape
This type of brain shell from the top of the skull to the posterior angle of the base of the skull (from the side view) into a large arc, the top of the skull is not higher than the eye, the sides of the brain shell are full, and the posterior angle of the base of the skull is higher than the ear foramen.
From the appearance, this kind of brain shell is easily mistaken for a larger arc and full sides, but because the top of the skull is not raised and the posterior horn of the skull base is higher than the ear hole. Therefore, the capacity is not large.
Category 2: slope-shaped gourd-shaped.
The brain shell of this type of brain is smaller, the cerebellar shell is larger, and the connection between the two narrows into a gourd,around the back of the skull, and the posterior angle of the skull base is slightly higher than the ear hole.
The disadvantage of this type of brain shell is that the brain shell is smaller and the brain part is narrower, and the cerebellum is more developed, in fact, the brain shell is very small.
Category 3: Rod shape.
This type of brain shell is divided into two types:
The craniosis of type 1 is rounded and gradually narrowed downwards, and the posterior horn of the base of the skull is higher than the ear foramen, and the posterior brain shell appears shorter.
The second type of skull has an oval and slightly inclined downwards, the left and right sides of the brain shell are full, the posterior horn of the base of the skull is much higher than the ear hole, and the posterior brain shell is short and inclined inwards.
These two types of brain shells are round and full from the appearance, especially the latter appears larger, but because the posterior angle of the skull base is much higher than the ear hole and closer to the ear hole, the posterior brain shell appears to be very short, so the capacity is not large.
Category 4: Right angles.
Type 1 has a cranial apex above the eye, forming a rounded right angle from the outside of the brain shell as viewed from the side. The sides of the brain shell are plump and flattened with the eye area. The posterior angle of the base of the skull is flat with the ear hole.
The second type forms a rounded right angle from the side of the brain shell, concave on both sides, or in a gourd-shaped shape, and gradually narrows backwards from the eye, and the posterior angle of the skull base is higher than the ear foramen.
The first type has a large capacity due to the flattening of the brain shell backwards, and the fullness of both sides of the brain shell, as well as the posterior angle of the skull base and the foramen of the ear, so the capacity is larger; the second type has a smaller capacity due to the higher concave and posterior horns of the skull base on both sides of the brain shell.
Category 5: Round.
Type 1 has a cranial apex higher than the eye, and the posterior angle of the base of the skull is flat with the ear hole and at a distance. Viewed from the side, the brain shell is in a circular arc, and its sides are full and form a plane with the eyes. This type of brain shell (viewed from the side) has the same arc as the circumference from the top of the skull to the posterior base of the skull, plus the bulge of the skull top, the posterior angle of the skull base is flat and far away from the ear hole, and the sides of the brain shell are full. Therefore, its capacity is larger than that of the other 4 categories. A good and ideal head shape.
The second type looks at the brain shell from the side in a circular arc, its craniosis is not higher than the eye, and the posterior angle of the base of the skull is higher than the ear hole. The left and right sides of the brain shell gradually narrow backwards. The capacity is small. Due to the narrow brain shell, this type appears to have a wider eye area. As a result, it is often mistaken for a larger head. In fact, the brain is not developed.
Of the 5 types of brain shells, only the 5th type is the best, and the 4th type is the second type. The rest are of the phased-out type.
4. The purpose of using the brain shell as the primary condition for selecting and retaining racing pigeons.
On the 25th day of the birth of the young pigeon, the basic type of brain shell can be observed and its fate is determined. If the observation is more accurate, the pigeon will be selected, and its brain shell will be longer and more beautiful, and conversely, the longer the non-instrument, the more prominent the shortcomings. Therefore, listing the brain shell as the primary condition for selecting and retaining racing pigeons is conducive to eliminating the individuals who are not successful as soon as possible, so as to save financial, material and manpower.
Young pigeons are born with the shape of the brain shell as the earliest, and a good head shape often appears with a good body shape. There are also many pigeons with beautiful bodies and insufficient brain shells that have achieved certain results, but the results will inevitably not create excellent results. The reason is that their posture is still insufficient, and there are shortcomings in precisely critical areas. However, all the pigeons that have achieved creative results, in addition to the other excellent conditions that must be possessed, obviously have a higher intelligent head.
Therefore, the second purpose of listing the brain shell as the primary condition for the selection of racing pigeons is to obtain individuals with developed minds and cultivate high-IQ groups in order to stabilize and improve the competitive performance.
5. The young birds selected must continue to be screened in combination with other conditions for racing pigeons.
The conditions for a pigeon to achieve good results are manifold. There are both external morphological and structural factors, as well as internal parts and genetic factors. Among the many factors, the mind is in a very crucial position. But things are intricate. As mentioned earlier: pigeons with good body shape and insufficient brain shell also have a certain result. On the other hand: not all pigeons with good brains can achieve good results. The reason for this is that the in vivo genes are not always consistent with the external morphology. However, it is certain that any pigeon with a good result must have a good brain shell, which is beyond doubt. Therefore, the brain shell remains, from beginning to end, the first and main condition for the selection and selection of racing pigeons.
