Non-professional answers. First of all, you have to have a carrier pigeon.
Take it to the place where you want to deliver the letter. And then put it. It will fly to where it used to live. It's your home.
It's used to living where you're going to deliver letters. It should be able to fly over after you release it from your house.
It's something to be trained. Point-to-point training.

One-way good solution, so that the recipient and the sender are breeding pigeons, after a period of time the two sides of the pigeon exchange, so that you want to send the letter to release the other party's carrier pigeon on it, if it is the same city in the place where you send the letter to feed, the place where the letter is fed. The pigeon will make both places home

Take it to the place where you want to deliver the letter, and then let it fly, and it will fly to your home. Start with 2 kilometers and work your way up.

Haha, that's funny, I think the people who know this kind of technology have passed away, and now that technology is so advanced, how can you think of letting pigeons send letters? Both tired pigeons are not good. Why bother.

This is a common bird brother rush. The first image of a pigeon found by archaeologists came from 3000 BC in Mesopotamia, in what is now Iraq. There are hundreds of species of pigeons that are widely bred all over the world, and these pigeons belong to the order Pigeonformes.
What we usually call pigeons is just one of the breed, i.e. they are nothing more than domestic pigeons. Why can carrier pigeons be sent with pigeons? A carrier pigeon, even if you take it to a strange place, can take the letter home because it will deliver the letter to your beloved and not to another person.
The pigeon's head and neck are surrounded by several small batteries, so that the pigeon's head creates a uniform magnetic field that allows the pigeon to feel moisture and heat in the air. When the current flows clockwise, the pigeons released on a cloudy day will fly in all directions, and then they will take them to a very high place, which is called heaven. Some people believe that the pigeon is a semiconductor with a resistance of 1000 ohms, and when the pigeon flies in the magnetic field of the earth-destroying ball, the wings of the pigeon will cut off the magnetic field lines, thus creating an induced electromotive force between the two wings, so the pigeon is considered to be a pigeon with sensing ability.
It turns out that on a sunny day it can choose the direction of flight according to the position of the sun, and the internal clock corrects the movement of the sun accordingly, so the original pigeon can be bolted to the polarized light guide phenomenon.

A carrier pigeon, even if you take it thousands of miles away to a strange place, it can bring the letter home. A few turns of coils are wound around the top of the pigeon's head and neck, powered by a small battery, and a uniform additional magnetic field is generated on the pigeon's head. When the current flows clockwise, the pigeons released on cloudy days will fly in all directions.
This shows that the pigeon is magnetically navigated. So how do pigeons navigate by geomagnetism?
Some people think of the pigeon as a semiconductor with a resistance of 1000 ohms, and when it flies in the Earth's magnetic field, its wings cut the magnetic field lines, thus creating an induced electromotive force (i.e., induced voltage) between the two wingsPigeons fly in different directions, and because the direction of the cutting magnetic field lines is different, the amount of electromotive force generated can be discerned. However, tests have shown that the additional magnetic field does not affect its flight when it is released on a sunny day, indicating that geomagnetism is not its only compass.
It turns out that the pigeon can measure polarized light, and on a sunny day it can choose the direction of flight according to the position of the sun, and the body's internal clock corrects the movement of the sun accordingly. It must be noted that when the current flows counterclockwise, it can fly home on a sunny or cloudy day.

Pigeons are trained to fly thousands of miles to get letters safely to their recipients, and almost never get lost. The pigeon itself has the ability to discern direction, and between the pigeon's eyes, there is a bulge above the beak, which can sense changes in the earth's magnetic field.

Raise for three months in a place where you can see the surroundings of your home, make a nest where the pigeon can perch, and the platform, first glue the seven primary flight feathers of the pigeon's wings together with tape, and then open the house in the sunny afternoon, at first only release one, open the house on an empty stomach, let the pigeon walk around the cage for an afternoon, and then feed it in the evening, the next morning, or the morning of the third day, remove the tape from the pigeon's wings, put a little less feed next to the cage, and then gently place the pigeon next to the cageDon't make sudden big moves, and at the same time avoid children around, cats and dogs, etc., wait until the pigeon stays at home for half a month, or see the pigeon flying for the first time in the second one, and then, let go of one every 5 days, so that the pigeon will not fly away in your house.

The principle of the pigeon message is very simple, it is the homing nature of the pigeon. Like what; The carrier pigeon of the landlord's house, you send a letter home at the school to bring the pigeon to the school, and when you send the letter, you release the pigeon and he goes home. The pigeon doesn't know anything else, he just knows how to go home.
If you want to send a letter between Shanghai and Beijing, you have to take the Shanghai pigeons to Beijing to raise them, and the pigeons will return to their home in Shanghai when the letter is delivered.

On sunny days, the sun is used as a compass, but when the sun is gone, they mainly refer to the senses of geomagnetism and smell.

How did carrier pigeons deliver messages in ancient times? Do pigeons really know where to go? After reading it, solve the doubts.

The pigeon has a magnetic field on its own navigation system.

You take the carrier pigeon to a different place, then put the letter in a special small letter box and tie it to the pigeon's leg, and after the pigeon is released, the pigeon sends the letter home.

Pigeons have a strong ability to discern direction and tenaciously homing home, which is an animal instinct, as for why? The jury is still inconclusive and is still being explored. This instinct of humans to be able to take advantage of pigeons has become a fact.
However, the pigeon also needs to be trained to use the animal's conditioned reflexes to familiarize it with the environment in which it is to reach its destination, and to be able to listen to human commands. That's how you can get the job done.
