Internet security breaches and government surveillance is reviving interest in the use of carrier pigeons to circumvent hackers and snoops.

There’s plenty of historical precedence for “pigeonets.” The ancient Egyptians were the first to train pigeons to relay messages as far back as 2900 B.C., and Julius Caesar used them to communicate over his far-flung empire.

Some 250,000 pigeons were employed during World War II to carry messages to and from Allied forces in Britain and the European front. In 2012, a Surrey man found the remains of one of the military pigeons in his chimney, with a red cylinder containing a coded message still attached to the bird’s skeletal leg.
