Osprey have been successfully reintroduced to England after a long absence, with monitoring programmes tracking individual welfare and breeding success.
Osprey reintroduction welfare demonstrates what is achievable with committed long-term monitoring and intervention. Tagged individuals provide welfare data throughout their lives enabling prompt response when individuals show signs of disease or injury. Lead poisoning from fishing tackle ingested by fish that ospreys eat is a preventable welfare harm. Anglers switching to non-lead fishing weights would directly protect the welfare of individual ospreys and other piscivorous raptors.
