At one time, Marin thought that the natural predators of carrier pigeons were humans. This is the view that he brought to the future generations, after all, the extinction of birds in later generations has a lot to do with human beings. But in fact, in this era, the ability of humans to kill birds is still limited. The main thing is because of the bullets.

In later generations, there were three main types of shotgun bullets used in human shotguns - bird bullets, deer bullets, and single-headed bullets. Among them, a bird bullet is a shotgun with the smallest single particle. The warhead of a bird bullet is not one of an ordinary bullet, but a lump of lead, and there are a lot of them. After the shotgun is fired, it will shoot a scatter, which is a range of hits.

Under the blow of a pile of lead, even a tiny sparrow could not escape death. Because, in the position of the target, there is a lead array with a net of many parts, and it is difficult to dodge.

It is precisely because of the appearance of shotguns that birds have suffered a catastrophe. Because, no matter how small and flexible a bird is, it is difficult to dodge the range of shotguns.

Because the effect of hitting birds was so good, arquebuses were introduced to the Ming Dynasty with shotguns in the mid-to-late 16th century, and the Ming people simply called them bird guns.

However, that was in the mid-to-late 16th century. Now, the prototype of shotguns, grapeshot, has not yet appeared, so naturally there are no shotguns that are very restrained from birds. Therefore, there are still many birds at the moment, and it is not too dangerous for carrier pigeons to fly through human settlements.

What the? You say shoot birds with bows and arrows? No kidding! Shoot a bird in flight with a bow and arrow, that's an absolute marksman. There may be many such people in the ancient northern regions of China, which paid attention to bows and arrows, but there are definitely not many in Europe. In addition, most of the birds shot with bows and arrows are large birds such as geese and swans, and it is difficult to shoot small pigeons. The one who can shoot the flying sparrow is definitely the god of arrows.

Because of the appearance of plate armor, the role of bows and arrows on the battlefield has been greatly reduced, and bows and arrows have almost become synonymous with uselessness. So, apart from England, which has a tradition in this area, there are very few people practicing archery in other countries. Even in archery, Europeans generally used crossbows rather than bows. This is because it takes a long time to practice archery with a bow, and it is not easy to practice well. And with the crossbow, it's very easy to get out of the way. After all, the crossbow has an aiming device, which is convenient for ordinary people who do not know how to shoot arrows.

But the problem is that the crossbow is much slower to reload than using a bow and arrow. If you see a carrier pigeon flying through the sky, and then look for a crossbow to reload and aim, the carrier pigeon will already fly far, far away.

Therefore, before the advent of shotguns, it was relatively safe for birds to fly over residential areas in Europe. On the contrary, it passes through the deep mountains and old forests, and it is easy to be eaten by falcons.

"In this case, I still have to build a traditional communication system!" Marin sighed, and could only continue to count on the post system and the clippers. After all, these two methods, although slow, are much safer than carrier pigeons, which are easily eaten by falcons......

Marin had thought of using a condor like Hai Dongqing to transmit a message (because the eagle itself was not afraid of being attacked by an eagle falcon), and Suha and his brothers had also demonstrated the skill of using Hai Dongqing to transmit a message. But the problem is that Haidong is wild and untamable, and they may be able to accept it for the owner and the owner's family. For strangers, do you touch it to try? Can't Catch You......

Only Suha and his younger brothers, because they are a family, are also familiar with each other. When the message is delivered, you can undo the note on the eagle's talons. If you change to an unfamiliar one, you will never be able to do it.

It is precisely because of this that although there are also messengers with eagles, there are very few of them, and they cannot be popularized. People who want to send messages can only rely on carrier pigeons. Big deal, put a few more carrier pigeons at a time. Even if you are unlucky enough to encounter an eagle falcon, you will be eaten one at a time, and the others will still be able to escape. As long as one of them brings the information, it will be considered to have completed the mission.

This depressed situation made Marin so depressed that he wanted to invent wireless telegraphy. However, after thinking about it, he reluctantly realized that he had no knowledge of radio in his mind.

In the physics books of junior high and high school, the principles of radio were introduced, but they were introduced very simply, and they deliberately did not mention how to make them. Why? Just because there was radio control in later generations. Therefore, the relevant technology is not disclosed. If it is not made public, Marin will naturally not be able to obtain the technology to make radios, so he can only stare dryly.

Fortunately, pigeons are not difficult to raise, at most raise more, be prepared to be eaten by the falcon halfway, there are always pigeons that can live to deliver the information......

But this is not a solution, as far as Marin knows, probably because the pigeons are delicious and delicious, and the falcon is especially fond of eating pigeons. In later generations, there were many falcons who sneaked into the pigeon cages on the roof to steal pigeons, just like weasels ran to the chicken coop to steal chickens.

Don't look at the large number of birds, falcons love to eat pigeons, which is very harmful to carrier pigeons. So, if you want to be safe in the air, you have to kill those falcons......

To this end, Marin issued an order to form a team of chasers, and if nothing else, he patrolled the flight path of carrier pigeons and hunted falcons.

Marin hesitated for a long time as to what weapons the falconers used, but decided to let the hunters use bows and arrows. Because, the falcon is larger and can reach about one meter with a wingspan, and the bow and arrow can also damage.

Moreover, Marin can organize hunters with strong archery skills to hunt falcons in an organized manner. It would be even more convenient if you brought a telescope.

Besides, Marin is not here to exterminate the falcon, which is unrealistic. In fact, all he wants is the safe and smooth route of the carrier pigeons.

Therefore, his falcon unit will only operate on the carrier pigeon route, and will not go to other places to find trouble with the falcon. Cleaning up the falcons on the route of the carrier pigeon can also make the carrier pigeon much safer.

In fact, the best weapon to fight a falcon is a shotgun. No matter how agile you fly, no matter how fast you fly, the shotgun is scattered and the hit rate is extremely high.

However, Marin was worried that after the introduction of the shotgun, others would think of grapeshot, which would be used in artillery to endanger itself, so he did not introduce the shotgun. Moreover, the falcon is so big, the bow and arrow are enough.

Marin even planned to have the falcons poison the dead pigeons, and hang the carcasses of the pigeons injected with the poison on the branches and sway, so that the falcons could eat them. After eating, the falcon will naturally die with a whimper.

……

Under Marin's attention, a group of veteran hunters who are good at using bows and arrows to shoot birds are singled out. Marlin equipped them with horses and bows and arrows, and let them patrol the pigeon route and hunt falcons. Kill one and reward one gold coin, which is 60 pfennig, which is equivalent to a month's salary for ordinary people. Of course, only falcons on the carrier pigeon's flight path are not counted.

Under the heavy reward, there will be brave men. Sure enough, after Marin issued a reward, the hunters of the falcon unit screamed and looked around for the falcon to shoot. As soon as they heard that there were falcons near the pigeon route, the gang would rush over to kill them. Even the falcon's nest is not spared, because Marin also rewards the destruction of the falcon's nest.

Because of these measures, the flight route of carrier pigeons in Beihai is much safer. The falcons were so frightened that they didn't dare to approach the pigeon route. Because, if they dared to come closer, a group of hunters who wanted to go crazy for their money would pounce on them and shoot them with a roar. In the eyes of the falcon hunters, these falcons are flying gold coins......
