As H5N1 bird flu devastates global wildlife, New Zealand is racing to protect some of its most endangered species, including the kākāpō, the world’s fattest parrot. With fewer than 250 left, a single outbreak could wipe them out.
The country’s Department of Conservation has completed a world-first trial, vaccinating 10 birds from five critically endangered species. Four, including the kākāpō, developed strong antibody responses lasting at least six months.
Officials aim to protect captive breeding populations before migratory birds arrive, though vaccinating wild flocks is seen as impractical and risky. Similar efforts abroad include the emergency vaccination of over 200 California condors in the US.
Scientists warn outdated vaccines and incomplete coverage could fuel viral evolution, yet many believe the benefits outweigh the risks. As one expert noted:
“If we start too soon, protection may fade. If we start too late, we might miss the crucial moment.”
For New Zealand’s rarest birds, vaccination may be their best chance at survival.
