Kiwi are among the world's most threatened birds, facing predation from introduced mammals. Predator management and captive hatching programs directly address their welfare and conservation.
Kiwi welfare is inseparable from predator management: in unmanaged forests, kiwi experience nearly certain death of their offspring and high adult mortality from stoat and cat predation. The welfare of surviving kiwi in intensively managed areas — with population support through Operation Nest Egg and surrounding predator control — is dramatically better. Captive-hatched kiwi chicks grow in facilities without the constant predation pressure of the wild, then release into monitored areas when large enough to survive. The welfare trade-off of captive incubation and early chick development (separation from wild parents, artificial environment) is clearly justified by the outcome: chicks that would have near-certain death in unmanaged forest instead survive to adult kiwi who can live and breed for decades. New Zealand's commitment to predator-free restoration is one of the most ambitious wildlife welfare and conservation programs globally.
