Homing pigeon
The homing pigeon is a variety of domesticated
Rock Pigeon (Columba livia) that has been
selectively bred to be able to find its way home over
extremely long distances. Because any
pigeon generally returns to its own nest and its own
mate, it was relatively easy to selectively breed the birds
that repeatedly found their way home over long distances.
Flights as long as 1689 miles have been recorded by
exceptional birds in competition pigeon racing. Their
average flying speed over moderate distances is around 30
miles per hour, but they can achieve bursts of speed up to
60 mph. Homing pigeons have been used to carry messages
written on thin light paper (such as cigarette paper) in a
small tube attached to one leg; this is called pigeon post.
This bird is to be distinguished from the
carrier pigeon, an entirely different breed.
Navigation
Some research has been performed with the intention of
discovering how birds can find their way back from distant
places they have never visited before. Some researchers
believe that pigeons navigate by
Earth's magnetic field. Near their home lofts, in areas
they have previously visited, pigeons probably are guided by
natural and artificial landmarks. Research by Floriano Papi
(Italy, early 1970s) and newer research published in the
February, 2004 issue of Animal Behaviour suggest that
pigeons also orient themselves by odors and/or combinations
of odors. (See the August 20, 2005 issue of Science News.)
Various experiments suggest that different breeds of
homing pigeons rely on different cues to different extents.
Charles Walcott at Cornell was able to demonstrate that one
strain of pigeons was confused by a magnetic anomaly in the
Earth that had no effect on another strain of birds. Other
experiments have shown that altering the perceived time of
day with artificial lighting or using air conditioning to
eliminate odors in the pigeons' home roost affected the
pigeons' ability to return home.
Some research also indicates that homing pigeons navigate
by following roads and other man-made features, making 90
degree turns and following habitual routes, much the same
way that humans navigate
[1].
History
Messenger pigeons were used as early as 1150 in Baghdad
[2] and also later by
Genghis Khan.
In
1850, Paul Reuter, who later founded Reuters press agency,
used a fleet of over 45 pigeons to deliver news and stock
prices between Brussels and Aachen. The outcome of the
Battle of Waterloo was also first delivered by a pigeon
to England.
Stamp for early Pigeon-Gram service
Possibly the first regular air mail service in the world
was Mr Howie's Pigeon-Post service from the Auckland New
Zealand suburb of Newton to Great Barrier Island, starting in 1896. Certainly the
world’s first 'airmail' stamps were issued for the Great
Barrier Pigeon-Gram Service from 1898 to 1908.
[3]
They were used extensively during World War I, and one
homing pigeon, Cher Ami, was awarded the French Croix de
Guerre for his heroic service in delivering 12
important messages, despite being shot once.
Eighty-two homing pigeons were dropped into Holland with
the First Airborn Division Signals as part of Operation
Market-Garden in World War II. The pigeons' loft was located in London
which would have required them to fly 240 miles to deliver
their messages.¹
Homing pigeons were still employed in the 21st century by
certain remote police departments in Orissa state in eastern
India to provide emergency communication services following
natural disasters. In March 2002, it was announced that
India's Police Pigeon Service messenger system in Orissa was
to be retired.
The humorous IP over Avian Carriers (RFC 1149) is an
Internet protocol for the transmission of messages via
homing pigeon. This protocol has been used, once, to
transmit a message in Bergen, Norway.
Notable pigeon enthusiasts in the United Kingdom include
Gerry Francis (football manager) and Duncan Ferguson
(Everton and Scotland footballer).
In
Chinese martial art (wushu) films and dramas, homing pigeons are often used for "Pigeon
Mail" (飛鴿傳書). People often labor under the misapprehension
that the pigeons know where to deliver the mail. The fact is
that they can only go back to one "mentally marked" point
that they have identified as their home. So "pigeon mail"
can only work when the sender is actually holding the
receiver's pigeons.
The
Taliban banned homing pigeons (or probably more
realistically the keeping of homing pigeons and/or the use
for sport) in Afghanistan.
