Electrocution on power lines kills an estimated 11-64 million birds annually in the US alone, with raptors - including golden eagles, bald eagles, ospreys, and red-tailed hawks - disproportionately affected due to large wingspan enabling contact between phases or phase and ground. Death from electrocution involves severe burns, cardiac arrest, and prolonged suffering in survivors with severe injuries. Power line electrocution is a leading non-natural cause of raptor mortality, significantly impacting populations of vulnerable species. Mitigation technologies include insulating sleeves on conductor and crossarm hardware, raptor deflectors preventing perching in dangerous positions, and underground cable replacement. US Fish and Wildlife Service Avian Protection Plans require utilities to assess and mitigate electrocution risk. Cost-effective retrofitting of high-risk poles is achievable; utilities with implemented programmes report 70-90% mortality reduction. International collaboration through the Convention on Migratory Species addresses raptor electrocution as a global conservation-welfare priority.
