New Zealand just had its first bird flu case. Now its taking a rare step to protect native birds

Key Points:

• New Zealand, known for its unique and endangered native bird species, has discovered two birds infected with the deadly H5N1 strain of bird flu, raising fears of extinction risks for its prized avian population.
• The country is urgently vaccinating 300 breeding pairs of five critically endangered native bird species, including the kākāpō and takahē, while implementing biosecurity measures such as restricting poultry movements and public warnings.
• New Zealand's isolated ecosystem, historically free of predatory mammals, has led to many flightless bird species that are highly vulnerable to disease, with over half of its 93 endemic species considered at risk of extinction.
• The virus, which spreads through droppings and saliva, poses a particular threat to seabirds and scavengers, and has already caused mass deaths in seal populations on nearby subantarctic islands, raising concerns for local fur seals and sea lions.
• Although the kiwi is not currently part of the vaccination program due to its larger population and solitary behavior, officials remain vigilant, emphasizing that bird flu is now a permanent threat requiring ongoing management and adaptation.
