Those signals, coming from tiny transmitters on a few dozen chunky, moss-green parrots, show that the kakapo – the world’s rarest and only flightless nocturnal parrot – has launched its first breeding season since 2022. For conservationists who track every bird by name, this year could reset the future of a species once thought beyond saving.
A comeback written in the shadows of the forest
The kakapo looks like a character out of a children’s book: a big, owl-faced parrot, mottled green like lichen, waddling through the undergrowth at night. It cannot fly. It freezes when threatened. For thousands of years in New Zealand, a land without native land mammals, that strategy worked.
Then people arrived, bringing rats, stoats and cats. By the early 20th century, kakapo were vanishing fast from the mainland. By the mid‑1990s, only 51 birds were left, scattered across predator‑free islands and hanging on through intensive human care.
Three decades of round‑the‑clock work later, the picture looks different. According to New Zealand’s Department of Conservation (DOC), there are now 236 kakapo alive at the start of 2026, including 83 females that are old enough – and healthy enough – to breed.
From 51 birds to 236 in thirty years, the kakapo’s climb has been slow but steady, measured clutch by clutch.
This makes the current season particularly charged. The last time the birds bred was in 2022. Since then, the forest has been quiet. Early January 2026 brought a change: motion sensors, cameras and radio tags picked up the first courtship movements and mating attempts, confirming that the species was gearing up for another reproductive window.
The secret trigger: a patient ancient tree
Kakapo don’t breed every year. Their reproductive cycle is tied to an equally unusual plant: the rimu, an endemic conifer that can live for centuries. Rimu trees sometimes produce huge crops of fruit in “mast” years, but those events are irregular and hard to predict.
When a mast year hits and the forest floor fills with fat, energy‑rich rimu fruit, female kakapo finally have the calories they need to produce eggs. Without that glut, they barely even come into breeding condition.
The kakapo’s love life runs on the schedule of a 600‑year‑old tree, not the calendar of humans.

The last major rimu fruiting happened in 2022, which triggered that season’s clutches. The trees have now done it again, prompting fresh activity in 2026. For ecologists, this tight link between bird and tree shows how fragile and finely tuned New Zealand’s ecosystems remain. If climate change or habitat loss disrupt rimu mast cycles, kakapo breeding could stall once more.
How kakapo romance works after dark
During a breeding year, males and females live almost separate lives. Males head to traditional display grounds known as leks. There, each male clears a shallow bowl in the soil or leaf litter. These bowls act as natural amplifiers for their booming calls.
Night after night, males inflate air sacs in their chests and emit deep, sub‑sonic booms that carry through the valleys. The sound can travel for kilometres, pulsing through the forest like a distant drum.
At the lek: a noisy competition
- Males dig and maintain bowl‑shaped depressions to enhance their calls.
- They boom for hours after dusk, sometimes losing significant weight in the process.
- Females visit leks briefly, select mates, then leave alone to nest and raise chicks.
Once mating is over, the female returns to a nest cavity, often under tree roots or in rock crevices. She lays a small clutch of eggs and takes on all parenting duty herself. In many seasons, only one chick per female survives to independence, which slows population growth even in good years.
Despite this natural limitation, programme managers think 2026 could set a new benchmark, with the potential to be the most productive season observed since structured records began three decades ago. That hope, though, is now balanced by a significant shift in how humans plan to “help”.
From intensive care to letting go
In earlier years, conservation teams intervened constantly. Staff would remove eggs for artificial incubation, hand‑rear chicks in specially equipped facilities and feed struggling mothers. The method saved lives and pushed numbers up, but it also created side effects that are now better understood.
Some hand‑raised birds imprint strongly on humans and struggle later with normal kakapo behaviour. The most famous example is Sirocco, a male who became a minor internet celebrity after repeatedly attempting to mate with people and television cameras. He symbolised both the success and the oddities of high‑touch conservation.
Conservationists are learning that saving a species is not just about numbers, but about culture, instincts and independence.
This season, DOC and its Māori partners, especially Ngāi Tahu, are deliberately stepping back. They plan to leave more eggs in nests, reduce handling of adults and limit interventions even in nests with multiple chicks. Staff remain on alert for clear emergencies, but routine interference is being scaled down.
New priorities for the 2026 breeding season
| Aspect | Past seasons | 2026 approach |
|---|---|---|
| Egg management | Frequent removal for artificial incubation | More eggs left with mothers in natural nests |
| Chick rearing | Hand‑rearing common for weak chicks | Preference for parental care whenever possible |
| Human contact | Regular nest checks and handling | Reduced visits, more remote monitoring |
| Goal | Maximise survival each season | Build a self‑sustaining, wild‑behaving population |
The long‑term aim is clear: kakapo that can live without constant human supervision. That will only be possible if large predator‑free areas exist, and if future generations of birds know how to behave like kakapo, not like feathered pets.
Re‑creating safe islands in a changing climate
At the moment, every kakapo lives on predator‑controlled offshore islands or in fenced sanctuaries. Each site demands traps, poison stations, dog patrols and a steady stream of funding.
New Zealand has a national vision of being free of key invasive predators, such as rats and stoats, by 2050. If that happens, conservationists hope that kakapo could one day return to parts of their former range on the main islands. Before that, they need to show that birds can manage without daily help.
Climate change complicates the picture. Warming temperatures can alter mast years for trees like rimu. More frequent storms increase the risk of nest failures. Managers run computer models that combine kakapo breeding data with climate projections to see how many birds might exist in 20, 50 or 100 years under different scenarios.
Under optimistic models, a few strong mast years like 2026 could push kakapo numbers past 300 birds by the early 2030s.
Under less favourable scenarios – with fewer mast events and more storms – population growth could stall or even reverse, even with ongoing predator control. That uncertainty puts extra pressure on the current breeding season. Every surviving chick adds resilience to a still‑fragile gene pool.
What this says about conservation in the 2020s
The kakapo story raises broader questions about how far humans should go to manage nature. Intensive methods can rescue a species from the brink, but they can also create animals that are dependent on people. A lighter‑touch strategy comes with its own risks: more eggs may fail, more chicks may die.
Conservation agencies now juggle three overlapping goals: preventing extinction, preserving natural behaviours and respecting the cultural values of Indigenous partners. For Ngāi Tahu, kakapo are taonga – treasured beings – and decisions about their future blend science with whakapapa, or lineage, and responsibility to ancestors and descendants.
For readers trying to make sense of the numbers, two terms are useful. A “mast year” is when certain trees produce an unusually large crop of seeds or fruit; many New Zealand species, from parrots to alpine parrots and beech‑dependent insects, time their breeding to these booms. A “lek” is a communal display site where males compete for mates through calls, dances or postures, seen in birds as varied as grouse, manakins and kakapo.
Later this season, as the first kakapo chicks hatch from mid‑February onwards, field teams will face hard choices: when to intervene with supplemental feeding, when to let natural selection play out. Their decisions will shape not only this year’s chick count, but the character of the wild kakapo flocks that people hope will still be roaming New Zealand’s forests centuries from now.
