It is very convenient for large rasstoyaniy
You may have heard about the ingenious Panamanian golden frog living near loud waterfalls and communicate with other frogs by gestures. Kuskou people living in a small Turkish village, no less resourceful: long before they appeared electricity, they came up with an ingenious way to communicate over long distances - the whistle.
They call it the bird's tongue, or Coos Dili, because the language has appeared in the village Kuskou, which in turn means "village of birds". This elegant method of communication was invented over 400 years ago as a consequence of living in the Pontic Mountains: rough terrain makes it very difficult to travel even short distances, and because of this, the villagers wanted to scream.
Inspired by birds singing, they began to whistle the Turkish word, and it turned out to be much more efficient and less energy-intensive way of communicating than yell or get to the person with whom you need to talk. Residents warn each other about the visitors, asking for help and invited to tea, they can even lead many difficult conversations using the whistle. This whistle is audible at a distance of one kilometer, if the distance is greater, the neighbors often assist each other services - peresvistyvayut message sent.
People Kuskou - close community. Electricity they finally got in 1986. The younger members of the people Kuskou soon realized the advantages of living in the more developed cities and moved there, but the old-timers left. Now language is slowly dying because everyone has a cell phone - these are the negative consequences of technological progress.
