Last year there were 40 collisions between airplanes and birds at the airport. That is three times as many as the year before, Swedish Radio's local radio reports. Birds that come into the airplane turbines can in the worst case scenario cause a crash.
The airport has now hired an ornithologist who will map birds in the area, and where they tend to eat and drink - while the "live scarecrow" is employed only for the summer season. He has green laser and squib to help him in his job, but tells Swedish Radio that by now, it often helps to just drive the car to where the birds are, since they know there will be a bang.
