Why can ancient homing pigeons deliver letters accurately?

Pigeons are very tough animals, which can usually maintain a speed of 90 kilometers per hour for several hours. But it has a characteristic, that is "homing". In other words, when it was born, it decided that the place where it was born was its home. When it grows up, no matter how far you take the pigeon to the ends of the earth, it can be found back!

Very unhappy, I want Qu Duan to call the troops together at once. Qu Duan handed Zhang Jun the roster of five armies and asked him which army he wanted to see. Zhang Jun called the First Army. Qu Duan immediately released 1 pigeon, and soon, the first army soldiers came armed to the teeth.

Pigeons navigate through the earth's magnetic field, landmarks, the sun and even infrasound waves, or through things that humans cannot perceive. In short, they won't get lost. The habit of returning home without getting lost was discovered and used by the ancients. So there are homing pigeons. Carrier pigeons have a long history and are widely used in communication.

The pigeon flew back to his home and sent the letter out. These are by no means caught casually in TV dramas. I feel that pigeons go wherever they are told to deliver letters. These are realized by using the homing pigeon's loyalty to home and the spirit of not dying or returning. Hope to adopt!

Of course, not all pigeons can be used to deliver letters. Only trained pigeons can act as homing pigeons. There are three situations in which carrier pigeons send letters. One is to take pigeons to different places and let them fly back to the pigeon house automatically. The second is two fixed points, that is, one point to feed pigeons and the other point to put dovecotes; The third is two moving points, which move the pigeon house within a certain range, take the pigeons to different places to fly, and the pigeons return on their own.

When releasing, release them individually, then collectively, then individually, and then release them directionally according to the competition route stipulated by the pigeon club. It is best to train in rain or shine, and exercise pigeons to dare to return to their nests in bad weather conditions.

Pigeons have a unique organ on their mouths, which can feel the changes of the earth's magnetic field and is very sensitive. A part of pigeon beak has magnetic particles. These magnetic particles will have different induction in different positions of the earth's magnetic field. When the magnetic field changes, pigeons will keenly capture this change, pigeons will smell this familiar "magnetic field strength" and go home.
