Insulate power pylons to prevent electrocution
Overall effectiveness category Likely to be beneficial
Number of studies: 1
Background information and definitions
Another method of preventing electrocution is to insulate parts of pylons that large birds are likely to touch at the same time.
Supporting evidence from individual studies
A before-and-after study in 2003 in urban environments in Tucson, Arizona, USA (Dwyer & Mannan 2007), found that there were significantly fewer electrocutions following the insulation of potentially dangerous elements of power pylons (1.4 electrocutions/nest before insulation vs. 0.2 electrocutions/nest afterwards). Any differentially energised hardware components, closer than 60 cm apart, on half the power poles within 300 m of 58 Harris’s hawk Parabuteo unicinctus nests were insulated.Study and other actions tested
