Homing pigeon
Summary
The homing pigeon, also called the mail pigeon or messenger pigeon, is a variety of domestic pigeons (Columba livia domestica) derived from the wild rock dove, selectively bred for its ability to find its way home over extremely long distances. The rock dove has an innate homing ability, meaning that it will generally return to its nest using magnetoreception. Flights as long as have been recorded by birds in competitive pigeon racing. Their average flying speed over moderate distances is around and speeds of up to have been observed in top racers for short distances.
Because of this skill, domesticated pigeons were used to carry messages as messenger pigeons. They are usually referred to as "pigeon post" if used in post service, or "war pigeon" during wars. Until the introduction of telephones, homing pigeons were used commercially to deliver communication.
Messenger pigeons are often incorrectly categorized as English Carrier pigeons, an ancient breed of fancy pigeons. They were used historically to send messages but lost the homing instinct long ago. Modern-day homing pigeons (homers) or racing pigeons (racing homers) do have "Carrier blood" in them because they are in part descendants of the old-style Carriers. This is one reason why they are still commonly but erroneously called "carrier pigeons".
Pigeon post
By 3000 BC, Egypt was using homing pigeons for pigeon post, taking advantage of a singular quality of this bird, which when taken far from its nest is able to find its way home due to a particularly developed sense of orientation. Messages were then tied around the legs of the pigeon, which was freed and could reach its original nest. By the 19th century homing pigeons were used extensively for military communications.
The sport of flying messenger pigeons was well-established as early as 3000 years ago. They were used to proclaim the winner of the Ancient Olympics.
Messenger pigeons were used as early as 1150 in Baghdad and also later by Genghis Khan. By 1167 a regular service between Baghdad and Syria had been established by Sultan Nur ad-Din.
