Txistu to save the hedgehogs

Especially in spring we see the hedgehogs treading cars on the roads. These small animals are heavily damaged by vehicles, but in Britain they have found a solution.

In the car is placed a small whistle that emits ultrasound and when the hedgehogs hear these sounds are standing. It is placed on the front bumper and when the wind passes through a kind of turbo emits ultrasound.
This type of txistu, born in the United States, is used by wide branches to prevent them from transiting the car capture road. In Britain, however, 100,000 hedgehogs, as many foxes and 50,000 badgers die on the road every year.
