Pigeon post is the use of homing pigeons to carry messages. Pigeons were effective as messengers due to their natural homing abilities. The pigeons were transported to a destination in cages, where they would be attached with messages, then naturally the pigeon would fly back to its home where the owner could read his mail. They have been used in many places around the world. Pigeons have also been used to great effect in military situations, and are in this case referred as war pigeon. ==Early history== As a method of communication, it is likely as old as the ancient Persians from whom the art of training the birds probably came. The Mughals also have used them as their messengers. The Romans used pigeon messengers to aid their military over 2000 years ago. Frontinus said that Julius Caesar used pigeons as messengers in his conquest of Gaul. The Greeks conveyed the names of the victors at the Olympic Games to their various cities by this means. By the 12th century, messenger pigeons were used in Baghdad. Naval chaplain Henry Teonge (c. 1620–1690) describes in his diary a regular pigeon postal service being used by merchants between İskenderun and Aleppo in the Levant.〔The Diary of Henry Teonge Chaplain on Board HM’s Ships Assistance, Bristol and Royal Oak 1675–1679.

The Dutch government established a civil and military system in Java and Sumatra early in the 19th century, the birds being obtained from Baghdad. In 1851, the German-born Paul Julius Reuter opened an office in the City of London which transmitted stock market quotations between London and Paris via the new Calais to Dover cable. Reuter had previously used pigeons to fly stock prices between Aachen and Brussels, a service that operated for a year until a gap in the telegraph link was closed. Details of the employment of pigeons during the siege of Paris in 1870-71 led to a revival in the training of pigeons for military purposes. Numerous societies were established for keeping pigeons of this class in all important European countries; and, in time, various governments established systems of communication for military purposes by pigeon post. After pigeon post between military fortresses had been thoroughly tested, attention was turned to its use for naval purposes, to send messages to ships in nearby waters. It was also used by news agencies and private individuals at various times. Governments in several countries established lofts of their own. Laws were passed making the destruction of such pigeons a serious offense; premiums to stimulate efficiency were offered to private societies, and rewards given for destruction of birds of prey. Before the advent of radio, pigeons were used by newspapers to report yacht races, and some yachts were actually fitted with lofts. During the establishment of formal pigeon post services, the registration of all birds was introduced. At the same time, in order to hinder the efficiency of the systems of foreign countries, difficulties were placed in the way of the importation of their birds for training, and in a few cases falcons were specially trained to interrupt the service war-time, the Germans having set the example by employing hawks against the Paris pigeons in 1870-71. No satisfactory method of protecting the weaker birds seems to have been developed, though the Chinese formerly provided their pigeons with whistles and bells to scare away birds of prey. However, as radio telegraphy and telephony were developed, the use of pigeons became limited to fortress warfare as early as in the 1910s. As an example, the British Admiralty discontinued its pigeon service in the early 20th century, although it had attained a remarkably high standard of efficiency. Nevertheless, large numbers of birds were still kept at the great inland fortresses of France, Germany and Russia at the outbreak of the First World War. In modern days, rafting photographers still use pigeons as a sneakernet to transport digital photos on flash media from the camera to the tour operator. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「pigeon post」の詳細全文を読む スポンサード リンク
