In ancient times, it was true that flying pigeons handed books.
After all, in ancient times, communication was troublesome, so pigeons were used to convey what they wanted to say. Moreover, it is also recorded in detail in Historical Records.
Flying pigeon and Hongyan have the same meaning, which is a communication method between the ancients. The letter is tied to the pigeon's feet and then passed to the person who wants to pass it on. In ancient times, communication was inconvenient, and smart people used many advantages such as pigeons flying fast and knowing the direction to domesticate pigeons and improve the speed of delivering letters.
Pigeons are very homesick birds, not only sensitive to the earth's magnetic field, but also naturally return to their nests. The ancients would set up a homing pigeon station somewhere and raise a large number of homing pigeons, making it their unique nest.
After long-term breeding and training, even if they are released outside, they will be eager to return to their nests. Therefore, when the ancients went out to send messages, they always brought homing pigeons. Even far away, pigeons can fly back to the station in time to deliver messages.
How do flying pigeons deliver letters?
Pigeons do have two brushes in this respect. Not all birds or animals have this ability. It takes a lot of time and energy to raise a homing pigeon that can only transmit information. In addition to careful breeding and scientific breeding, a series of professional training is needed to maximize the homing ability of pigeons. Only with the above conditions can you become a qualified carrier pigeon.
All pigeons will be used by the ancients to make carrier pigeons. Pigeons not only have strong homing ability, but also have strong endurance and super memory. They also have the characteristics of strong cold and heat resistance, and at the same time have the ability to feed in the wild, so they are raised to deliver letters. Moreover, it can find its way home according to the magnetic field of the sun, buildings and the earth, which has to be admired by pigeons. Even humans can do it easily.
Pigeons can use sunlight to navigate, and their internal biological clock can choose the direction with the moving direction of sunlight, so there is no need to worry about being hungry and getting lost. As long as it flies once, the pigeon will fly back according to its own memory. Pigeons have the ability to fly long distances. Pigeons can fly 60 to 100 kilometers per hour and can carry objects that are 10% larger than their own weight. The speed is not worse than or even better than that of a horse.
There is a common-sense mistake in using "flying pigeons to pass books" to convey military information in TV dramas.
The first common sense error, carrier pigeons will never fall into the hands of one person, especially generals (including heroes). The principle of homing pigeons transmitting books is realized by homing pigeons.
To take advantage of this feature, it is necessary to have specialized personnel to raise and train pigeons. The cultivated people are definitely not generals and heroes, nor are they free. So pigeons can only return to their nests and will never fall into the hands of generals.
The second common-sense mistake is that the information transmitted by homing pigeons is one-way. Because homing pigeons only remember the nest where they grew up, they can only fly back from the battlefield and can't go back. Some people say it can be spread by carrier pigeons. That won't do either. Who would put a homing pigeon in a war place and let it go home?
