Homing pigeon in the context of English carrier pigeon

Pigeon photography is an aerial photography technique invented in 1907 by the German apothecary Julius Neubronner, who also used pigeons to deliver medications. A homing pigeon was fitted with an aluminium breast harness to which a lightweight time-delayed miniature camera could be attached. Neubronner's German patent application was initially rejected, but was granted in December 1908 after he produced authenticated photographs taken by his pigeons. He publicized the technique at the 1909 Dresden International Photographic Exhibition, and sold some images as postcards at the Frankfurt International Aviation Exhibition and at the 1910 and 1911 Paris Air Shows.

Initially, the military potential of pigeon photography for aerial reconnaissance appeared interesting. Battlefield tests in World War I provided encouraging results, but the ancillary technology of mobile dovecotes for messenger pigeons had the greatest impact. Owing to the rapid development of aviation during the war, military interest in pigeon photography faded and Neubronner abandoned his experiments. The idea was briefly resurrected in the 1930s by a Swiss clockmaker, and reportedly also by the German and French militaries. Although war pigeons were deployed extensively during World War II, it is unclear to what extent, if any, birds were involved in aerial reconnaissance. The United States Central Intelligence Agency (CIA) later developed a battery-powered camera designed for espionage pigeon photography; details of its use remain classified.

Pigeon racing is the sport of releasing specialized, trained homing pigeons, which then return to their homes over a carefully measured distance. The time it takes the animal to cover the specified distance is measured, and the bird's rate of travel is calculated and compared with all of the other pigeons in the race to determine which animal returned at the highest speed.

Pigeon racing requires a specific breed of pigeon bred for the sport, the Racing Homer. Competing pigeons are specially trained and conditioned for races that vary in distance from approximately 100 kilometres (62 mi) to 1,000 kilometres (620 mi). Despite these lengths, races can be won and lost by seconds, so many different timing and measuring devices have been developed. The traditional timing method involves rubber rings being placed into a specially designed clock, whereas a newer development uses RFID tags to record arrival time.

Pigeon post is the use of homing pigeons to carry messages. Pigeons are effective as messengers due to their natural homing abilities. The pigeons are transported to a destination in cages, where they are attached with messages, then the pigeon naturally flies back to its home where the recipient could read the message. 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 to as war pigeons.

Homing pigeons have long played an important role in war. Due to their homing ability, speed, and altitude, they were often used as military messengers because they were less likely to be intercepted by enemy forces. Carrier pigeons of the Racing Homer breed were used to carry messages in World War I and World War II, and 32 such pigeons were presented with the Dickin Medal. Medals such as the Croix de Guerre, awarded to Cher Ami, and the Dickin Medal awarded to the pigeons G.I. Joe and Paddy, amongst 32 others, have been awarded to pigeons for their services in saving human lives. Pigeons had a 95% success rate in delivering their messages.

During World War I and World War II, carrier pigeons were used by the Australian, French, German, American, and UK forces, to transport messages back to their home coop behind the lines. When they landed, wires in the coop would sound a bell or buzzer and a soldier of the Signal Corps would know a message had arrived. The soldier would go to the coop, remove the message from the canister, and send it to its destination by telegraph, field phone, or personal messenger.

Homing is the inherent ability of an animal to navigate towards an original location through unfamiliar areas. This location may be a home territory or a breeding spot.
