New Zealand's kākāpō — the world's heaviest parrot, and one that can't fly at all — just posted its biggest baby boom in over a decade, and it couldn't be more badly needed for a species this close to the edge.

  • 90 chicks were officially added to the population in a single 2026 season, a new record
  • 325 kākāpō are now alive, the highest total of the recovery era
  • 51 birds, 20 of them female, was the entire population when recovery efforts began in 1995
  • 4 years — the longest gap ever recorded between kākāpō breeding seasons

From 51 Birds to a Record Season

Kākāpō almost vanished entirely. Introduced predators like cats, rats, and stoats wiped out most of the population before conservationists intervened, leaving just 51 birds by 1995. Since then, New Zealand's Department of Conservation and Ngāi Tahu have run a dedicated Kākāpō Recovery Programme through 13 breeding seasons.

This year's season was worth the wait. The department confirmed the 325-bird count is the highest since the species' modern recovery began — and possibly the largest kākāpō population in 75 years. It took 16 years for the programme to produce its first 90 chicks combined. This year, one season did it alone.

Kākāpō only breed when rimu trees produce a bumper fruit crop, which happens unpredictably every few years. The birds went four full years without breeding this time — their longest gap on record — which makes the size of this season's rebound even more striking.

How Rangers Pulled It Off

Every kākāpō wears a small backpack transmitter so rangers can track its movements and monitor nesting in real time. That data lets conservation teams intervene early when eggs or chicks are at risk, without needing to physically check every nest by hand.

This season, the recovery team deliberately tried something different: less intervention, not more. They relied more heavily on remote nest-monitoring technology and cut back on egg checks and supplementary feeding, testing how much kākāpō can now manage on their own.

"We had a four-year gap between breeding seasons, so it's fantastic to finally see the population increase after all that time," said Deidre Vercoe, DOC's Kākāpō Recovery Operations Manager.

Tāne Davis, who represents Te Rūnanga o Ngāi Tahu on the Kākāpō Recovery Group, said the shift matters as much as the numbers. The goal, he said, is figuring out "where intensive intervention is still needed and where we can start to return to more natural levels of kākāpō breeding outcomes."

What Comes Next

There are still only three breeding populations of kākāpō, all confined to predator-free islands: Whenua Hou/Codfish Island, and Fiordland's Pukenui/Anchor Island and Te Kāhaku/Chalky Island. Nearly every founding bird of the modern population originally came from Rakiura (Stewart Island), and Davis says a predator-free Rakiura remains the long-term goal — giving kākāpō an ancestral home to eventually return to.

Most of this year's chicks will receive names on the anniversary of their hatch dates next February and March, following kākāpō tradition. But DOC says a small number will stay unnamed, marking a symbolic step toward treating the growing population more like a wild species and less like an intensively managed one.

Based on current fruiting patterns, the recovery team's early modelling suggests the next breeding season could arrive by 2028 — a two-year gap rather than four. If that holds, kākāpō may be entering a steadier, more predictable stretch of recovery than they've had in 30 years.
