Releasing captive-bred birds to supplement wild populations is a key conservation strategy for threatened species. But the welfare of birds through captive rearing, conditioning and release deserves careful attention alongside population outcomes.
Conservation release programmes have achieved remarkable successes, including the recovery of peregrine falcons, white-tailed eagles and California condors. But welfare during every phase — hatching, rearing, conditioning, transport and release — affects both individual bird welfare and programme success rates. Stress protocols, soft-release methods and post-release support such as supplementary feeding reduce both suffering and mortality. Well-designed welfare standards for conservation release programmes benefit birds and conservation outcomes simultaneously.
