Installation of markers on high-voltage lines leads to 75% fewer bird collisions

Installing markers on high-voltage lines leads to a sharp drop in the number of bird collisions, according to a Natuurpunt study commissioned by Elia.

Markers ensure that birds see a high voltage line sooner so they can avoid colliding with it. Natuurpunt monitored an overhead line in Noordschote before and after markers were installed. The findings are clear: after installing markers, the number of bird collisions plummeted 75% to 95%. Elia plans to continue its efforts and aims to install markers on about 200 km of the highest-risk high-voltage lines by 2030.
