Kākāpō Files II

The first chick of the 2026 kākāpō breeding season has successfully hatched on Pukenui/Anchor Island. DOC’s Kākāpō Recovery Programme reports that Tiwhiri-A1-2026 hatched in foster mother Yasmine’s nest on 14 February 2026 and is the first kākāpō chick in four years. Huhū-A1-2026 is due to hatch on Whenua Hou imminently. Sixty-two kākāpō nests have been found so far and the egg tally is nearly 200, of which 78 are known to be fertile. More eggs are expected. Alison Ballance visits Whenua Hou, meets some of the kākāpō rangers and reports on the technology that enables the Kākāpō Team to conduct 24-hour surveillance on each bird.

Almost 90% of adult female kākāpō of breeding age have mated so far this breeding season, and two thirds of those are nesting. Some birds have already laid a full clutch of eggs and while some clutches are 100% fertile, others are - as expected - unfortunately infertile. To date there are 55 fertile kākāpō eggs, and that number grows daily as kākāpō rangers find nests and are able to check the developing eggs. Alison Ballance checks in from Whenua Hou, where technical advisor Daryl Eason is nearing the end of the artificial insemination programme. He is excited that a ‘lost’ female has been found and wonders if she is also nesting.

More than three-quarters of female kākāpō of breeding age have mated so far, and the number of nests is growing rapidly. Kākāpō operations manager Deidre Vercoe tells Alison Ballance that 101 eggs have been laid to date, and while it is early days 38 eggs are known to be fertile. As always, infertile eggs are a major problem, although science advisor Andrew Digby explains that recent research shows that many eggs are in fact fertilised but die in the first day or two. And Deidre says that the Kākāpō Recovery Programme takes threats such as the fungal disease aspergillosis, failure of the rimu fruit to ripen and the possible arrival of highly pathogenic bird flu in New Zealand very seriously.

The 2026 kākāpō breeding season is all systems go: nearly half of the females of breeding age have mated and so far 15 females are nesting. Technical Advisor Daryl Eason talks about record-breaking female Ongaonga who, at 4 years-old, is the youngest female kākāpō ever to breed. There are plenty of other first-time breeders as well. Six females were successfully inseminated with sperm from under-represented males. Ranger Maddy Whitaker updates us with the latest numbers, including a single fertile egg so far, and tech expert Jake Osborne introduces the kākāpō nest cam, beaming live from Rakiura’s nest on Whenua Hou.

There have been 24 kākāpō matings so far, and the number is increasing as mating action heats up on all three breeding islands. Deidre Vercoe, from the Kākāpō Recovery Programme, tells Alison Ballance that some 7-year-old birds from the 2019 breeding season have mated for the first time. The first female to mate this season, Pearl, has laid infertile eggs, but nightly activity monitoring shows that three more females have started nesting. Technical Advisor Daryl Eason talks about the under-achievers, founder kākāpō that either haven’t bred at all or have produced only a few chicks.

Early bird Pearl has laid the first eggs of the 2026 kākāpō breeding season but Kākāpō Recovery Programme science advisor Andrew Digby tells Alison Ballance that it’s too soon to know if they are fertile. Youngsters Huhū and Hondy are the third pair to mate on Whenua Hou, and Heather and Bluster Murphy are the fourth. Hine Taumai and Henry are the first to mate on Anchor Island. Technical advisor Daryl Eason explains the use of artificial insemination (AI), and we find out why it is a useful genetics tool and what the AI team are up to in the field.

It’s the New Year and we’re in the early days of a big kākāpō breeding season. Daryl Eason from the Kākāpō Team tells Alison Ballance that Esperance and Ian are the second kākāpō to mate, and he expects that any minute now there will be plenty more birds mating. The kākāpō population drops to 236 birds. Science advisor Andrew Digby explains why every living kākāpō has had its genome sequenced, and what genes can reveal – including why some kākāpō have olive feathers and others are bright green. And we meet over-achievers Flossie and Blades.

It’s nearly the New Year and we’re counting down to the start of a big kākāpō breeding season. Island ranger Maddy Whittaker tells Alison Ballance that Pearl and Boss are the first kākāpō to mate. Deidre Vercoe, operations manager for the Kākāpō Team, explains that kākāpō mums on Whenua Hou will get wrap-round support, while management on Anchor Island and Te Kakahu/Chalky Island will be more hands-off. Scientist Andrew Digby talks about the role of technology in making this possible, and digs into the kākāpō’s boring gut microbiome. Technical advisor Daryl Eason introduces founder female Margaret-Maree, matriarch of a lineage with five living generations.

It’s the summer solstice and we are waiting for kākāpō breeding to begin. Alison Ballance chats with island ranger Maddy Whittaker, who reports that on Whenua Hou/Codfish Island all the male kākāpō are in full voice, booming all night to attract the females, who haven’t shown any interest yet. The action hasn’t yet ramped up on Anchor Island. Alison also meets three key people from the Kākāpō Team, and hears about their first-ever kākāpō encounters.
