Kākāpō Files II

Six months after this record-breaking kākāpō breeding season began, all 91 living chicks have fledged and left the nest. The chicks remain with their kākāpō mums and are still being fed by them, as well as eating a range of plant material, and as cold wet midwinter weather sets in the chicks are learning to find dry roost sites. The Kākāpō Team’s Daryl Eason and Andrew Digby answer listener questions, including why did Kākāpō cam star Rakiura spend so much time in the nest digging, what can you learn from a piece of egg shell, and could old museum specimens be a source of lost kākāpō genes?Send any Kākāpō Files questions and comments to kakapo@rnz.co.nzIn this episode:02:06 – Island news with ranger Daniella Whitaker06:21 – Update on Kākāpō Cam star Rakiura11:43 – Sick kākāpō15:19 - Are kākāpō smart?18:19 - Previous nest cams20:05 - Why did Rakiura dig so much in her nest?24:00 - Do kākāpō compete with other species?25:30 - Kākāpō on Coal Island and at Sanctuary Mountain Mangatautari30:57 - Museum specimens and lost genesLearn more:Follow the Kākāpō Files podcast to keep up to dateListen to the Voice of the Kākāpō series for a recap of the 2019 breeding season.

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.Send any Kākāpō Files questions and comments to kakapo@rnz.co.nzIn this episode:00:00 – Introduction00:51 – Mating updates03:06 - Nesting updates06:27 - Artificial insemination progress10:40 - Male under-achievers14:09 - Female under-achievers15:26 - Closing creditsLearn more:Follow the Kākāpō Files podcast to keep up to date.Listen to the Voice of the Kākāpō series for a recap of the 2019 breeding season.

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.

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.Send any Kākāpō Files questions and comments to kakapo@rnz.co.nzIn this episode:00:00 – Introduction00:42 – Kākāpō ranger Maddy Whittaker with updates on what the male birds are up to on the islands05:09 – Technical Officer Daryl Eason talks about his first kākāpō encounter and what makes these birds so unique09:41 – Operations Manager of the Kākāpō Recovery Programme Deidre Vercoe remembers her first kākāpō meeting13:44 – Science Advisor Andrew Digby talks about meeting his first kākāpō16:00 – Daryl Eason predicts when the breeding season might begin…Go to this episode on rnz.co.nz for more details

In 2019 Alison Ballance followed the bumpy, rollercoaster ride that was the kākāpō breeding season. Now she returns, six years on, to do it all over again. We'll meet familiar characters, of both the human and bird kind, as well as new faces. Will the chicks born in 2019 start to breed? How will the team fare with a more hands-off approach? Will the deadly aspergillosis that surfaced in 2019 return? And with the rimu mast predicted to be big, could this be the most successful breeding season yet? First episode drops 16th December.

In July 2023 four male kākāpō were released into the fenced Sanctuary Mountain Maungatautari – part of a new habitat trial to investigate suitable locations for the growing kākāpō population. But after a further six were introduced, the kākāpō began to wander – beyond the fence. A year on, and several escapes later, what’s been learned? And what’s next for kākāpō in Maungatautari? There are plenty of night-time wanderers in New Zealand that you might expect to come across driving on back roads – rats, mice, a seemingly endless number of possums.But it’s not often that you round a corner to come face to face with a kākāpō.Elwin’s escapadeThis was the surprising sight that faced Tyler James Lindsay very early one morning in January 2024.A Cambridge local, Tyler was driving a milk tanker along Scott Road, northeast of Sanctuary Mountain Maungatautari, when suddenly he saw before him a strange shape.“Just a big green bird. Just in the middle of the road looking straight at my lights, I think it was rather confused,” he says.Luckily, Tyler is into native birds, so he was aware that kākāpō had been introduced to the fenced sanctuary six months earlier. He knew exactly what he was looking at.The next day, Tyler’s report made its way to Sanctuary Mountain Maungatautari kākāpō ranger Dan Howie, who quickly began the search for the elusive Elwin.“Such an incredible interaction that he saw this bird out there – in the middle of the road no less – which is absolutely terrifying as kākāpō ranger,” says Dan.But this was not the first time, nor the last, that Dan would feel that fear.The habitat trialKākāpō numbers are growing. In 1995 there were just 51 kākāpō and the threat of losing them forever was all too real.A decade ago, around the time that Dr Andrew Digby joined the Kākāpō Recovery team, there were just over 120 kākāpō. Today there are 247.Intensive management and three quite successful breeding seasons have enabled this doubling of kākāpō numbers in the last 10 years. Initially, the challenge was to save the charismatic, flightless parrots from extinction. Now, the team also has an added challenge: where to put them.To date, the majority of kākāpō have lived on offshore predator-free islands in the rohe of Ngāi Tahu – Whenua Hou / Codfish Island next to Rakiura / Stewart Island, and Pukenui / Anchor Island in Fiordland. But these islands are getting full…Go to this episode on rnz.co.nz for more details

Alison Ballance joins the kākāpō recovery team on Pukenui Anchor Island to hear how the 2021/2022 kākāpō breeding season is going.It's been very quiet on the kākāpō front for the last two years, but this year is another big one for the rare bird.In 2019, the endangered flightless night parrot had its largest breeding season on record, as recounted in the RNZ podcast series the Kākāpō Files and Voice of the Kākāpō. After a rollercoaster ride of successes and setbacks, 72 chicks fledged, temporarily boosting the kākāpō population to 213 birds.Since then, there has been a slow attrition due to deaths of both old and young birds, which saw this breeding season kick off with 201 birds.Most importantly, this number included 57 females of breeding age, which are spread across three southern kākāpō islands: Pukenui-Anchor Island (in Fiordland), Te Kakahu-Chalky Island (also in Fiordland) and Whenua Hou-Codfish Island (near Stewart Island). Forty six of those females have bred this year, laying a grand total of 139 eggs.By autumn, 57 chicks out of the 60 that hatched were doing well, most of them being raised by their mothers or foster mothers. In previous breeding seasons many chicks have been hand-reared, but Deidre Vercoe, manager of DOC's Kākāpō Recovery Programme, says that this year the team was taking a more hands-off approach. This meant no double clutching, and most eggs were left to hatch in nests rather than in incubators.There is now a much greater reliance on technology to allow remote monitoring, with every bird wearing a smart radio transmitter that sends information about the wearer to a centralised computer database. Te Kakahu-Chalky island is the most hands-off breeding island, and indications from activity records being sent remotely from the three nesting mothers suggests they are still raising the island's three chicks.Aspergillosis outbreakUnfortunately, the onset of autumn marked a bit of a turning point in the breeding season. After a period of hot dry weather in Fiordland, the female Jemma, on Pukenui Island, died from aspergillosis. This fungal disease can be deadly, with nine kākāpō dying from it in the 2019 breeding season, although a number of other kākāpō were successfully treated.A second Pukenui female, Roha, has since been diagnosed with severe aspergillosis and is fighting for her life at Auckland Zoo. Some chicks are at the Dunedin Wildlife Hospital being treated for aspergillosis as well as injuries such as broken legs…Go to this episode on rnz.co.nz for more details
