For the first time in four years, kÄkÄpĹ are breeding again.
Experts are optimistic that 2026 could deliver the most productive breeding season for the kÄkÄpĹ in decades. These critically endangered, flightless, nocturnal parrotsânative exclusively to New Zealandâare among the world's heaviest and most intensively managed bird species. Their reproduction is highly irregular, occurring only every two to four years when native rimu trees undergo a "mast" event, producing an abundance of protein-rich fruit and seeds that provide the essential nutrition for egg-laying and chick-rearing.
After a four-year hiatus since the last major breeding in 2022, the pattern has shifted dramatically this year. A significant rimu mast is underway, triggering widespread mating activity that began as early as late December 2025. Males congregate in traditional leksâcommunal display areasâwhere they construct intricate networks of cleared tracks and bowl-shaped depressions to amplify their deep, booming calls. These resonant, low-frequency sounds carry far through the dense forest, attracting females for courtship.
The KÄkÄpĹ Recovery Programme, run by New Zealand's Department of Conservation (DOC) in partnership with NgÄi Tahu, now monitors the entire known population of 236 individuals (as of early 2026), including 83 breeding-age females. Every bird is fitted with a small radio transmitter to track movements, mating behavior, and nesting success in real time. Females typically produce one to five eggs but usually fledge just a single chick per season, meaning even high participation could yield a substantial influx of youngâpotentially the highest number since systematic records began 30 years ago.
Conservation strategies for kÄkÄpĹ rank among the most hands-on globally: decades of efforts have included hand-rearing chicks, supplemental feeding, predator-free island translocations, and vigilant nest protection. For 2026, however, managers are deliberately scaling back intervention in many casesâallowing more eggs to incubate naturally and permitting mothers to raise offspring with less human involvement. This approach aims to foster greater self-sufficiency and resilience in the population.
As Deidre Vercoe, operations manager for the kÄkÄpĹ recovery program, explained: âWe want to create healthy, self-sustaining populations of kÄkÄpĹ that are thriving, not just surviving.â A robust food supply combined with reduced interference could mark a pivotal step toward that goal. If the season fulfills expectations, with chicks hatching from mid-February onward, it would represent meaningful progress in pulling this iconic species back from the edge of extinction.
