Electric tools surprise the direction of birds
A research conducted in Germany proved that the electric appliances can affect the sense of direction of animals. Science discovered that the radio signals in the AM band and the electromagnetic areas formed by electrical appliances installed in the socket affect the sense of the animals. The researchers believe that in cases of flying over the cities of birds, this effect is more.

According to the news contained inBBC English, research on the influence of electrical appliances on animals was published in Nature magazine. Prof. Henrik Mouritsen, the University of Oldenburg in Germany, who carries out the research, states that they are quite skeptical about the relationship they found at first. When you encounter an unexpected effect according to Mouritsen, your evidence needs to be stronger. For this, scientists say they have worked on this topic for more than 7 years. Mouritsen emphasizes the fact that they share with the public findings that are sure of the results. [
Some birds have an exceptional sense of direction. They add half of the world during migrations. It allows them to find ways of a nevi secret magnetic compass birds that allow them to detect magnetic fields on the world. Prof Mouritsen noticed that the luck work affects birds of low-frequency waves while studying birds from the redger. Mouritsen says there is a very simple experiment of research on the sense of direction of birds and explains the process:
"We put the keys into a kind of outdoor lower aluminum closed direction cage. Birds throw away from here. We detect the direction that they go when they exit. If you create a static magnetic field in the horizontal plane, birds fly towards the other direction. This method is applied in different parts of the world since 40 years. "

Fakat German scientists noticed that they did not fly birds when they tried this method in Oldenburg. Ta ki sievetomenyatic audio up to 100 times reduced. Thus, birds begin to fly again.
Mouritsen and his team are doing a lot of experiments to understand the effects of low electromagnetic areas over 7 years after you notice it. At the end, they noticed that birds lost their sense of direction in the electromagnetic sound range between 5 kHz and 5 MHz frequencies. When the electromagnetic area is removed, birds can find the repeat directions.
Mouritsen states that the birds who migrated are flying over the cities, many electric tools are affected by the sense of birds because of their establishments and houses. But the reason for Mouritsen, which makes birds feel completely lost:

“There are three kinds of compasses of keys: Star, sun and magnetic compass. These work independently. Magnetic compass also helps them with sun and star compass even problems. “
