    It’s the summer solstice and we are waiting for kākāpō breeding to begin.

    Kākāpō Files II 06 | Kākāpō Action Heating Up

    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.

    Kākāpō Files II 07 | Full Steam Ahead

    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.

  8. Kākāpō Files II 08 | Peak Breeding

    EPISODE 8

    Kākāpō Files II 08 | Peak Breeding

    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.
