All top pigeon which we have examined, had soft feathers. They just slipped through your hands. This is also one of the similarities between top pigeons. Soft and greasy feathers.
8th & 9th feather
The fat content of the feather is extremely important to create the hydrophobic effect. In addition to this it is also important for the protection of the wings, and the smooth movement. Did you know that the greasy spot on the primary flight of the 8th and 9th feather has a function? It ensures you that this greasy dust is distributed across other feathers while flying. These feathers remain fit and wear out less quickly.
Some heavier types of birds tend to have a thicker forearm than the lighter pigeons. That is logical because a heavier pigeon has to lift on more weight. The length of this forearm has to be short. A pigeon that makes many strikes with his wings with a short arm can “lift” easily.
Test it yourself!
You can test it by yourself by putting your fore finger and middle finger on the forearm to explain (underside of the wing). You feel a lump in the joint. Your index and middle finger should be just between their front arm und the upper arm. This is approximately 4 to 5 inches long. Now for the primaries (active wing) and secondary’s flights feathers or rear (passive wing).
Most top pigeons have superb curves at the last four primaries. This is necessary for the simple fact that the primaries become weak and pull up in moisture and fog. This makes the pigeon handicapped. Thus he misses the power shovel. Think of the oar of a boot nicely bent.
Between the top pigeons which have narrow primary feathers are also the pigeons with wider primary feathers. We personally like to see some space between the last four primaries for more ventilation. The carrier pigeon must row in the air. He does not need to float on the thermals of air. Here short flight feathers or a long and active rear wing is needed. When the feathers are long, there is no speed in the rowing strikes of the wing.
When the feathers are long, there is no speed in the rowing strikes of the wing. We particularly look at Sprint pigeons their flight feathers and an offset of 1,5 cm between the primary flight feather and the first secondary feather. With distance pigeons, this difference is less. It is less important as well. For them the flight feathers are stronger and more opaque on each other. Pay particular attention to the relationship between the length of the secondary and primary (active flights) feathers in each wing. Make sure they always balance. The pins of the secondary feather towards to the body are curved and have to overlap like roof tiles. Only then there is proper closed position of the secondary feather.
For example, no air can escape during the downward movement when flying. There is an optimal flight capacity created. You can test the secondary feather by yourself. Stretch the wings and try with your four fingers under the secondary feather (rear) and push the pins upwards. This should be firm. Your four fingers should not simply go through puncture. Another comparison: what about the formation of the wings. Exactly the same as the example of the convex (parabolic) shape of the wing of an airplane. The wind that will go against it, will follow his path. Because of the longer path, the wind is at the upper side of the wing and the shorter way at the lower side of the wing, the wing gets more upward pressure. We speak about aerodynamics.
