How does a pigeon send a letter to find a way home?

The ancient Egyptians captured the mailing ability of the dove. But at that time, the miraculous ability of the postman bird was still a secret.

Science explains the pigeon's ability to deliver letters

Post-navigation pigeons (Columbia Livia) used low-frequency sound waves to map and find their way home.

How did the birds find their way home when they flew out of the city for thousands of miles of nautical miles? In a sense, they were based on their sense of smell like a clock or compass. In fact, all of these hypotheses are too complicated, while pigeons often rely on the natural environment of familiarity and artificial landmarks to identify territories close to home.

British scientists have shown that: Birds will fly along small roads, to highways, fly across the streets and fly around in a circular way, even if this means that their flight will Rise a few miles nautical miles. A recent study found that pigeons capture very effectively roads when they fly in pairs. If there are companions, they will be smart enough to make the path shorter than when flying alone.

In long journeys, pigeons calculate the necessary flight direction by comparing the position of the sun with their clock in them. By raising pigeons under artificial lighting, scientists have influenced their ability to recognize time and trick them into flying in the wrong direction.

To further prove the ability of other pigeons to find their way home, scientists have carried out a multitude of different experiments, including cutting their olfactory nerves . When a marbles are cut off, the pigeon will not be able to find its way. Top scientists have acknowledged the ability of pigeons to find the olfactory flight direction.

But both are still hypotheses and not really convincing.

Accordingly, in certain areas such as Castor Hill and Jersey Hill in the United States, the birds always fly in the wrong direction when trying to find their way home even though they do not encounter this problem elsewhere.

Elsewhere near the town of Weedsport (USA), the young birds flew in the wrong direction and the older birds did not. There are also certain days where all birds released in these locations can find their way back without any problems.

Going into the analysis, scientists found that the Columbia Livia pigeon could hear low-frequency sound waves , only 0.1 to 0.2 Hz. Negative waves can be emitted from the ocean and slightly disturbed in the atmosphere, most likely pigeons rely on sound waves to guide.

So they sketched a negative map of low-frequency sounds on weekdays and the days when the birds could find their way back from Jersey Hill.

As a result, the researchers found that, due to the atmospheric and topographic conditions, Jersey hill was in a ' sound shadow'.

Therefore, there is little or no negative flow that can reach this area except for one day when the wind and temperature patterns change. That time coincides with the day the pigeons can find their way back without incident. This phenomenon is similar to Castor Hill but here, the low-down lines are diverted and deflected.

This finding is considered to be the answer to pigeon studies in this area. But there are many other studies that support hypothesis such as pigeons that use electric currents from Earth or use sniffles .

However, the way each bird uses to determine its direction may vary depending on the location of the barn and its habitat.

In some places, they will use hype lines but elsewhere they can use sniffing. But the unchanging truth is the bird's ability to find great paths.
