A before-and-after study in a wetland national park in Andalusia, Spain (Ferrer & Hiraldo 1991), found that adding perches to 80 electricity pylons did not reduce electrocution rates of Spanish imperial eagle Aquila adalberti. This study discusses other eagle management techniques, described in ‘Bury or isolate power lines’, ‘Use signs and access restrictions to reduce disturbance at nest sites’, ‘Foster eggs or chicks with wild conspecifics’ and ‘Remove/treat endoparasites’.
