White-tailed eagles were reintroduced to Scotland in 1975 after 70 years of extinction and are now expanding across Britain. Conservation efforts support individual eagle welfare.
White-tailed eagle reintroduction programs have imposed specific welfare costs and benefits on individual birds. Translocated Norwegian birds and their descendants face risks during establishment — competition with established pairs, failed breeding attempts, and learning to exploit unfamiliar prey. Satellite tracking reveals that birds establishing in new territories spend more time traveling and invest more energy in exploration than established pairs — a welfare-relevant energy cost of reintroduction.
Illegal persecution remains the most significant individual welfare threat. Satellite-tracked eagles frequently disappear in areas managed for game bird shooting. Those recovered dead show evidence of poisoning or shooting. Each illegally killed eagle represents direct welfare harm and removes a breeding adult from a slowly growing population. The welfare of the surviving eagles is affected by this ongoing persecution pressure.
