The so-called homing pigeon, as the name suggests, is a communication pigeon. When communication tools were underdeveloped in ancient times, people took advantage of pigeons' strong desire to return home and, after training, used them to deliver messages much faster than ancient horses. Although there is a saying of "a thousand-mile horse", it is only a thousand miles in one day, and in fact it cannot run a thousand miles. Most of them will change to another horse or rest before going again when they arrive at the inn. However, homing pigeons can fly thousands of kilometers a day. 500 kilometers can be reached in 6 hours. The speed of short-distance homing pigeons can reach more than 100 kilometers per hour. With the advancement of technology, the method of pigeon communication has gradually been replaced. In addition to military and very few commercial uses, people have given homing pigeons a new task, which is to participate in racing competitions. Pigeons used in competitions can be divided into breeding pigeons and racing pigeons (some breeding pigeons can only be used for breeding and are not suitable for competition, and they will fail if they compete; and some homing pigeons can only be used for competition and cannot be kept for breeding, so they are reserved for breeding. Its offspring are poor; there are also all-round homing pigeons that can both compete in competitions and retain seeds, which are very few). Therefore, homing pigeon is the general term for racing pigeons and breeding pigeons.
