Kākāpō population hits 75-year high after record breeding season

Overview

Updated Sep 3

New Zealand's kākāpō population hit 325 birds on September 1, 2026—the first time the world's heaviest parrot has topped 300 in roughly 75 years. The jump came from a record breeding season: 90 chicks survived to independence and joined the official count.

The rebound began in 1995, when the population had collapsed to 51 birds. Now the program faces a new problem: its predator-free islands are full, and the team is testing how much human help kākāpō still need to keep growing.

Why it matters

Kākāpō rebounded from 51 to 325 birds—but the islands that shelter them are full, so finding new habitat is the next test.

Key Indicators

325

Current kākāpō population

Official population after 90 chicks were added on September 1, 2026.

Chicks added in 2026 season

Record number of chicks that reached 150 days old, the independence milestone.

258

Eggs laid in 2026 season

258 eggs laid by 79 nesting females; 106 hatched, 90 survived to independence.

Population when recovery began in 1995

Just 20 females remained when the Kākāpō Recovery Programme started.

Years since population last topped 300

DOC estimates the last time numbers exceeded 300 may have been 75 years ago.

Scenarios

Kākāpō population tops 400 after 2028 breeding season

Likely Resolves by End of 2028

Discussed by: DOC's own modeling, cited by Andrew Digby and Deidre Vercoe

Temperature patterns that trigger rimu mast fruiting point to another breeding season in 2028—only two years after 2026, versus the four-year gap between the previous two seasons. If the rimu crop is strong and chick survival matches 2026 rates, the population could grow by roughly 80 birds and pass 400.

Kākāpō move to a fourth predator-free site

Possible Resolves by Jun 1, 2028

Discussed by: Deidre Vercoe; National Geographic reporting on habitat limits

All three breeding islands were at capacity before the 2026 season. The program is scouting new sites, including Te Puka-Hereka, which may hold a few stoats. Moving females there would be the first time female kākāpō have lived alongside stoats in decades—a test of whether the birds can handle a predator the program has spent 30 years removing.

Flat funding forces the program to scale back

Uncertain Resolves by Oct 31, 2027

Discussed by: Andrew Digby; National Geographic reporting on program finances

National Geographic reported that staff numbers stayed flat as the population doubled, and government funding plateaued before dwindling—leaving the team reliant on a corporate sponsor and donations. If the budget doesn't grow, the program may need to reduce monitoring or intervention just as the population needs more room.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

1982–present

California condor recovery (1982–present)

By 1982, only 22 California condors remained in the wild. Scientists captured every surviving bird for captive breeding—a gamble that critics warned could doom the species.

Then

Captive breeding worked; the first condors were released in 1992.

Now

The population now exceeds 500, with more than 300 in the wild—though every bird still wears wing tags and many depend on managed food sources.

Why this matters now

Like the kākāpō, condors were rebuilt from a tiny founder group through decades of intensive management, and they remain dependent on human support today.

1974–present

Mauritius kestrel recovery (1974–present)

In 1974, just four Mauritius kestrels were known to exist, making it the world's rarest bird. Conservationists used captive breeding, nest boxes, and predator control to rebuild the species.

Then

The population recovered to a few hundred birds within two decades.

Now

The kestrel is the classic proof that a bird species can rebound from a founder group smaller than the kākāpō's 1995 low.

Why this matters now

The kestrel shows what sustained, species-specific intervention can achieve—though the kākāpō's reproductive cycle is far slower.

1941–present

Whooping crane recovery (1941–present)

The whooping crane population fell to about 15 birds in 1941. Decades of habitat protection, captive rearing, and ultralight-led migration training rebuilt it.

Then

Numbers climbed slowly through the mid-20th century as the last wild flock was protected.

Now

The population now exceeds 500 wild and captive birds, though the species remains endangered.

Why this matters now

A long-lived, slow-reproducing bird whose recovery spans decades—the same timescale as the kākāpō's comeback.
