Kākāpō population hits 325, breaking 300 mark after 75 years

The Department of Conservation (DOC) announced on Tuesday that the total number of living kākāpō – the world’s only flightless, nocturnal parrot – has risen to 325 individuals after 90 chicks were successfully fledged this spring, marking the first time in 75 years that the population has surpassed the 300‑bird threshold. The milestone was reached across several of the species’ recovery sites, including the remote offshore sanctuary of Whenua Hou (Codfish Island) where the latest cohort of hatchlings was released into the wild.

The kākāpō (Strigops habroptilus) has been teetering on the brink of extinction since the arrival of humans in New Zealand, when habitat loss and predation by introduced mammals drove its numbers down to a low of 51 birds in the late 1990s. Recognized as one of the planet’s most endangered avian species, the bird’s unique biology – a heavy, ground‑dwelling body, a low reproductive rate of one egg every two to four years, and a strong reliance on native forest – makes recovery especially challenging. Conservationists have therefore pursued an intensive, hands‑on approach that combines predator‑free islands, intensive monitoring, and assisted breeding.

DOC, New Zealand’s public service agency tasked with protecting the nation’s natural heritage, leads the kākāpō programme in partnership with the New Zealand Conservation Authority (NZCA) and a network of fifteen regional conservation boards. These bodies coordinate community involvement, provide advisory input to ministers, and oversee the allocation of resources for on‑the‑ground work. Over the past two decades, the programme has moved all remaining kākāpō to predator‑free sanctuaries, installed artificial nesting burrows, and employed “hand‑rearing” techniques where eggs are incubated and chicks are fed by staff until they can fend for themselves. The recent batch of 90 chicks, raised in a dedicated hatchery on Whenua Hou, benefitted from refined feeding protocols and genetic management designed to maximise diversity and reduce inbreeding.

Crossing the 300‑bird mark is more than a symbolic achievement; it signals a measurable shift in the species’ trajectory toward a self‑sustaining population. Nonetheless, experts caution that the kākāpō remains vulnerable. The birds still occupy a handful of isolated islands, and any disease outbreak or severe weather event could jeopardise the hard‑won gains. Continued investment in biosecurity, habitat restoration, and genetic monitoring is essential to move the species beyond the “critically endangered” classification and toward a status of “vulnerable” in future assessments.

The significance of the kākāpō recovery extends beyond New Zealand’s borders. Island ecosystems worldwide face similar pressures from invasive species and habitat fragmentation, and the methods refined by DOC – particularly the integration of community‑based boards, rigorous scientific oversight, and predator‑free island models – offer a template for other nations grappling with endemic wildlife loss. For Taiwan, an island nation with its own suite of threatened birds such as the Mikado pheasant and the Formosan blue magpie, the kākāpō success story underscores the importance of coordinated governmental agencies, local stakeholder involvement, and long‑term commitment to species‑specific recovery plans. As global supply chains and tourism increasingly intersect with fragile habitats, the lessons learned from New Zealand’s kākāpō programme provide a practical reference point for preserving biodiversity and maintaining ecological resilience across the Asia‑Pacific region.
