Ospreys have successfully recolonised the UK after decades of absence. Nest platform installation and protection of nesting pairs has been central to this recovery.
Individual ospreys face mortality risks during migration including shooting in Mediterranean countries and drowning from fish too large to release while airborne. Nest disturbance by well-intentioned birdwatchers causes egg chilling and abandonment. Nest platform installation provides stable, predator-resistant nest sites that increase breeding success over natural alternatives in some habitats. Satellite tagging carries temporary capture stress but provides conservation data that guides range-country protection efforts. Wildlife crime against ospreys including nest disturbance and egg theft requires active wardens during the breeding season.
