Add perches to electricity pylons to reduce electrocution

How is the evidence assessed?

Study locations

Key messages

A single before-and-after study in Spain found that adding perches did not reduce electrocutions of Spanish imperial eagles Aquila adalberti.

 

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. 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’.
