Wild Sounds: Kākāpō Files II

The biggest kākāpō season on record has come to an end, with a bumper number of chicks reaching the milestone of 150 days old. The 90 chicks have boosted the kākāpō population from 235 birds to 325, an increase of more than a third. The 2026 season saw 48 kākāpō mums produce living chicks, fathered by 32 dads. The ‘top dad’ was 10-year Tūterangi, breeding for the first time, who fathered 10 chicks with six females. Ten chicks were fathered with the help of artificial insemination. DOC’s Kākāpō Recovery Programme reports that not all of this year’s chicks will be named, and that they expect the next breeding season to be in two years’ time.Send any Kākāpō Files questions and comments to [email protected] this episode:00:00 – Introduction01:42 – Deidre Vercoe announces 90 chicks and population of 325 kākāpō04:45 – Naming kākāpō06:00 – Daryl Eason on the identity of the dads10:27 – 10 chicks fathered through artificial insemination15:59 – Andrew Digby on stepping back from intensive management18:20 – next breeding season in 202824:43 – Deidre Vercoe on predator-free habitats28:58 - Closing credits…Go to this episode on rnz.co.nz for more details

The oldest chick of the 2026 kākāpō breeding season, Tiwhiri-A1 has reached 150 days old and can be officially counted. This milestone increases the kākāpō population by one bird to 236, the first time it has risen in 4 years. The first chicks to reach independence are roosting away from their mums and feeding themselves, and two chicks have dropped their transmitters and are now “off-grid”. With the threat of deadly H5N1 bird flu looming, vet Lydia Uddstrom explains that about a quarter of the most genetically valuable kākāpō will be vaccinated against bird flu, especially on Whenua Hou, which has a large population of seabirds.Send any Kākāpō Files questions and comments to [email protected] this episode:00:00 – Introduction02:30 – Island news with ranger Louise Porter13:45 – Highly pathogenic H5N1 bird flu17:28 - Vet Lydia Uddstrom on bird flu vaccinations26:10 - How do kākāpō contract aspergillosis27:37 - Are any kākāpō on display28:20 - Frozen sperm29:17 - How kākāpō use space37:06 - Are kākāpō cuddly38:00 - Closing credits…Go to this episode on rnz.co.nz for more details

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 [email protected] this episode:00:00 - Introduction02:06 – 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.

Half of the chicks from this record-breaking kākāpō breeding season have fledged and left their nests for good, but are still being fed by their mums. The tally of living chicks has dropped to 92 with the death of a chick from Te Kākahu/Chalky Island. Veterinary advisor Lydia Uddstrom reports that a 4-year-old female is being treated for cloacitis, a mysterious infection with no known cause that has infected a number of birds in the past few years. Kākāpō rangers give potted histories and breeding season updates for nine birds that are part of a symbolic adoption programme.Send any Kākāpō Files questions and comments to [email protected] this episode:00:00 – Introduction01:00 – Vet Lydia Uddstrom with island news06:24 - Adult female Tōrua treated for cloacitis11:20 - Adoption birds13:22 - JEM breeding season update15:57 - Marama breeding season update18:14 - Waikawa breeding season update21:28 - Nora breeding season update24:24 - Bluster Murphy breeding season update27:05 - Sinbad breeding season update29:55 - Kuia breeding season update32:48 - Rahotu breeding season update35:05 - Rangi rediscovered37:50 - Closing creditsLearn 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 seasonAlso listen to the episodes covering the interim 2022 breeding season, and about how a few male kākāpō have fared in the North Island, in the fenced Sanctuary Mountain MaungatautariFor more New Zealand science and nature find and follow the Our Changing World podcast, and subscribe to the show’s monthly newsletterGuests:Kākāpō veterinary advisor, Lydia Uddstrom, Kākāpō Recovery ProgrammeKākāpō ranger, Jess Wagner, Kākāpō Recovery ProgrammeKākāpō ranger, Sarah LittleKākāpō ranger, Theo ThompsonReferences:…Go to this episode on rnz.co.nz for more details

The tally of confirmed living kākāpō chicks goes down with two further deaths, but gets a welcome boost with the confirmation of a living chick in a previously inaccessible nest. This brings the number of living chicks to 93, ranging in weight from 770 grams to nearly 2.5 kilograms. On all three kākāpō breeding islands, the oldest kākāpō chicks are fledging and leaving their nests. They are still accompanied and fed by their mothers, but find their own shelter. Before chicks leave the nest for good, kākāpō rangers visit to insert microchips as a permanent identification, and to attach transmitters that enable the Kākāpō Team to locate the chicks and monitor their activity levels remotely.Send any Kākāpō Files questions and comments to [email protected] this episode:00:00 – Introduction02:34 – Big chick Huhū-A1 using a special ramp to leave the nest05:23 – Ranger Petrus with the latest island news06:44 - A chick is finally confirmed in Rimu’s cliff-top nest10:09 - Two more of Waa’s chicks die so latest living chick tally is 9311:46 - Update on Pearl-B3 and sick chicks13:17 - Chick transmitters19:55 - Tanē Davis on Ngāi Tahu’s relationship with kākāpō27:35 - Vet Lydia Uddstrom and Vori’s story32:34 - Closing credits…Go to this episode on rnz.co.nz for more details
