Prevention of Mortality and Power Outages on 22 kV Lines Related to Mute Swan Collisions by Using Bird Flight Diverters in Slovakia

One of the biggest threats for the wild living species of birds is collisions with power lines causing thousands of avoidable deaths and injuries. This problem in Slovakia is mainly associated with the mute swan (Cygnus olor). To determine the effectiveness of bird diverters and also their role in reducing the power outage rate, we selected one section of the 22 kV line near the village of Kalinkovo, in the western part of Slovakia.
