A New Dawn for the World’s Rarest Parrot — “Bumper” Season Ahead for kākāpō

Scientists working on the recovery of New Zealand’s critically endangered kākāpō believe 2025 may mark the biggest breeding season on record – a potential turning point decades in the making.

There are 84 breeding-age female kākāpō in the population – a dramatic increase from just 20 females when the recovery programme began in 1995. Scientists from University of Auckland report an exceptional fruit set on rimu trees – the key ecological cue that typically triggers kākāpō breeding. If conditions hold, every one of those 84 females could attempt nesting – a rare alignment of favourable ecological, genetic and population-level factors.

Professor Jacqueline Beggs, chair of the Kākāpō Recovery Group, says this could be “the best breeding season since records began.” The kākāpō is globally unique: it is a flightless, nocturnal parrot and the only parrot in the world that uses a lek-breeding system. Males gather on ridge-tops to “boom” – loud vocalisations that attract females. The females alone raise the chicks.

The species’ population has been rebuilt from the brink of annihilation: in 1995 there were only 51 known kākāpō, with just 20 females. Much of the intense conservation and breeding work over the past three decades – including habitat protection, predator eradication, egg-incubation efforts, medical care, and population monitoring – has laid the groundwork for the potential boom we may see this season. Even so, kākāpō long-term recovery remains delicate:

• They breed only when rimu mast (fruiting) occurs – about every 2–4 years.

• Their genetic diversity remains limited after the severe population crash, increasing vulnerability to disease, environmental change, and demographic events.

If this year’s predicted breeding surge delivers, the benefits will be significant:

• A substantial increase in the overall kākāpō population – improving genetic robustness and long-term viability.

• A stronger foundation for expanding the species beyond existing sanctuaries – easing pressure on limited “safe” islands, and enabling potential reintroductions to restored mainland habitats.

• A symbolic victory for conservation in Aotearoa – evidence that sustained, careful human intervention can reverse even the gravest declines in wildlife populations.

As Prof Beggs reflects: what was once a species “in intensive care” could now be moving toward a future where kākāpō live more freely, spread over more areas, and reclaim larger swaths of their original range.

The road ahead remains risky. Some of the major challenges that could derail even a record-breaking season:

• If weather or environmental conditions change – e.g. unexpected storms, poor fruit ripening, or predator incursions – many nests may fail.

• Overcrowding on sanctuary islands could lead to increased competition, nesting interference, or disease spread among birds.

• The limited genetic pool continues to place the population at risk, particularly to infectious disease or environmental stress.

Conservationists warn that success depends not just on this season’s outcome – but on long-term commitment to habitat expansion, predator control, genetic monitoring, and careful management of future breeding cycles.

• Support predator-free sanctuaries and restoration projects – broader habitat is vital for future kākāpō expansion.

• Back research and monitoring programmes – long-term data helps conservationists make informed decisions.

• Be aware of biosecurity – avoid introducing pests (rats, stoats, cats) to islands or mainland areas earmarked for reintroduction.

• Engage with kōrero (talk) and Mātauranga-Māori perspectives – kākāpō are taonga, and their recovery reflects the aspirations and responsibilities of tangata whenua.

The signs are clear: 2025 could mark a historic turning point for kākāpō – from a species teetering near extinction, to one on track for a major population surge. But the moment demands vigilance, care, and long-term commitment.

If all goes well, by late 2026 we could see many more of these extraordinary, ancient parrots thriving – a powerful testament to the possibility of wildlife renewal, and a hopeful reminder that with care, respect, and determination, we can restore what was nearly lost.
