White-tailed eagles were extinct in England for 240 years before reintroduction began on the Isle of Wight in 2019. Understanding their welfare needs and the challenges of reintroduction provides a case study in raptor conservation.
White-tailed eagle welfare during reintroduction requires careful management of the stress of translocation, the challenges of establishing territories in unfamiliar landscapes, and the risks from power lines and human disturbance. Tracking data from reintroduced birds shows extensive movements that expose them to multiple mortality risks. Long-term, established populations in suitable habitats show good welfare with natural breeding behaviour and foraging success. The welfare case for reintroduction is strong -- restoring a species to its natural habitat creates conditions where animals can express full natural behaviour.
