Ospreys undertake remarkable long-distance migrations from European breeding grounds to West African wintering sites, with welfare challenges throughout their biannual journeys.
Individual ospreys tracked by satellite face documented welfare risks at specific bottleneck points along their migration routes including power lines in Spain and fishing gear entanglement at West African wintering sites. The consistency of individual migration routes means that risks identified through tracking can be addressed at specific locations. Power line insulation along known osprey flight paths and reduction of fishing line pollution at key wintering lakes protect individual birds whose routes have been mapped through years of satellite monitoring.
