Scientific evidence
Scientific studies into the issue of bird electrocution have been conducted across many regions of the world, with particular attention paid to the subject by researchers in Spain and the USA. Coordination between conservation agencies and power supply companies has been developed to address the issue of electrocution in countries such as Germany and Hungary, while recent growth in the electrocution problem has been documented in Asia and Africa.
The first work with high-speed filming of how raptors alighted on power-poles, to help produce safe designs, was done by falconers in the USA fifty years ago, and falconers are still funding work to make power-lines bird-friendly.
These studies highlight the common features of poorly designed infrastructure that result in bird electrocutions across the globe, while variation in landscape, habitat characteristics and avifauna produces specific regional distinctions.
