Ospreys have recovered strongly in the UK after near-extinction. Understanding individual osprey welfare and the factors that determine breeding success informs ongoing conservation management.
Individual osprey welfare is closely tied to fishing success and nest security. Fish availability in the lake or river system supporting a breeding pair directly determines whether chicks are adequately fed and fledge successfully. Nest disturbance during the sensitive incubation period causes egg abandonment and is a direct welfare harm. Lead poisoning from fishing tackle fragments in fish is a preventable welfare cause of osprey mortality. Supporting osprey breeding sites through reduced disturbance, clean fishing practices, and fish stock management improves both individual welfare and population outcomes.
