Noise negatively affects not only residents of the metropolis, but also birds living in airports. This was revealed during observations of shabby wands.
Biologists studied the behavior of birds living in Britain and The Netherlands both near airports and at a distance of 20 and 50 km from them. Chunks forced to hear the buzz all the time taking off the plane, began to sing quieter. Scientists believe that the reason for this is the hearing impairment of birds.

Another difference between birds living in air harbors, from shadows living in quiet areas – a lot of aggression. Some airport dwellers even attacked speakers from which sounded like bird singing.
