What are the characteristics of a pigeon s wings

The wings of a pigeon have the characteristics of flight.

The pigeons are divided into fast pigeons: the main feathers should be sharpened and long and the wind is good, the main feather area should account for 70% strong, and the secondary feather area should account for 30% weak; Flyer or long distance pigeons: 60% of the main feathers, 40% of the secondary feathers, and most of them are dark gray or dark spots; If the proportion of the main and secondary feathers is 50%, it can basically be divided into inferior ribs, and the elimination should be the best policy; High speed pigeon:

The indirect part of the secondary main feather should be excellent, and the length should have a significant drop, that is, the secondary feather should be short and the main feather should be long; In the races with low velocity and with the longer distance high pigeons, most of the main and secondary pigeons do not fall far behind.

The dove has a broad and flat head and a large and deep body, 53 to 56 cm long from beak to tail, 38 to 40 cm in bust, and a long and slightly curved beak. The eye rings of the adult pigeons are red or flesh red, and the eye rings of the young pigeons are pink. Other Names:

Pigeon, columba distribution area: Global classification: chordates, vertebrate subphylum, birds, fantail subclass, pigeon order, dove, pigeon subfamily, pigeon genus, 3035 lifespan:

15 20 years.

The wings of the pigeon have the following characteristics: the pigeon wing bone is small, the feather peduncle is strong and elastic, and the flexibility is very good; When the pigeon's wings are opened, its wings** are very smooth; The length of the main wing of the pigeon is longer than that of the secondary wing, and the length of the feather has a certain sense of layering.

1. The pigeon wing bone is small, the feather peduncle is strong and elastic, and the flexibility is very good.

The peduncle is elastic, strong and flexible. The pigeon's wings are the power aid for the pigeon to move forward and suspend in the air when flying**, it can be said that the pigeon's strong musculature drives the frequency of the wings, so that the pigeon's fear of beating the wings produces a driving force to bring the pigeon to fly forward.

2. When the pigeon's wings are opened, its wings are very smooth.

In fact, the role of the main feather and the secondary feather are the same, they are also the power source that pushes the pigeon to fly at high speed and hang in the air, this buoyancy and speed is determined according to the shape of the pigeon's wings, and the connection of the main and auxiliary feathers and the shape of the secondary feathers.

3. The length of the main feather of the pigeon's wings is longer than that of the secondary feather, and the length of the feathers has a certain sense of hierarchy.

This flapping process completes this series of flight maneuvers with the flapping of the main feather and the diversion of the secondary feathers, and makes the diversion air produce a forward propulsion, allowing the pigeon to fly at high speed in the air. This is the characteristic of the wings of a pigeon.

The pigeon's arms are very flat and flexible, the length of the main wing of the pigeon wing is longer than the aile, and the length of the feathers must be layered.

1. The pigeon's body is streamlined, it is good at flying, its body surface is covered with more feathers, and its chest muscles are more developed.

2. Pigeons are bipedal, constant temperature vertebrates, and the feathers on their bodies can be divided into positive feathers (mainly used for flying) and down feathers (mainly used for heat preservation); The pigeon's forelimbs have evolved into wings, while it also has a hard beak (the pigeon's mouth).

3. The pigeon's rectum is relatively short, so it eats a lot and digests quickly (the digestive system is developed), which helps it lose weight and thus facilitate flight.

4. The pigeon's heart has 2 atria and 2 ventricles, and its heart rate is fast and the body temperature is relatively constant; In addition to the lungs, the respiratory organs also have air sacs that protrude from the lung walls, which help the lungs to breathe double.

5. The pigeon belongs to the oviparous, its body temperature is generally 42, its sternum has a well-developed keel process, and the bone is hollow and inflated, which is the bone structure characteristics that the pigeon has evolved after adapting to flight life.

The quality of the pigeon can be seen from the wings, generally the wings are small, the feathers are strong and elastic, and the flexibility is very good. When the pigeon's wings are opened, it feels like its wings are loose and the wings are very smooth. The length of the main wing of the pigeon is longer than that of the secondary feather, and the length of the feather should have a certain sense of layering.

The pigeon's wings can see its quality, usually the pigeon's wing bone is very small, its feather peduncle is strong and elastic, and the flexibility is very good, the pigeon's wings are very flat, indicating that it has little resistance to flying.

When the pigeon's wings are opened, if the pigeon has great stability, it will easily open the wings, and it will feel that its wings are very loose, and the wings are smooth when going up**.

The length of the main wing feather of the pigeon is longer than that of the secondary feather, and the length of the feather should have a certain sense of layering, and the secondary feather should be placed on the pigeon's back, and the overall look is more rounded.
