Wild Sounds: Kākāpō Files II

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.

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.

Alison Ballance spends a week on Whenua Hou/Codfish Island, one of three kākāpō breeding islands. She follows rangers from DOC’s Kākāpō Recovery Programme as they go about their daily and nightly nest visits to check on the rapidly growing chicks. All but one of the 23 nests on Whenua Hou have just a single chick, as the rimu fruit has failed to ripen and kākāpō mums are relying on supplementary food to raise their chicks. During the week, the chick Queenie-A3 is found dead, and there is news from Pukenui/Anchor Island of another chick dying in a flash flood that swept through the nest.

DOC’s Kākāpō Recovery Programme says that the 2026 kākāpō breeding season is officially the biggest on record, and that all chicks have now hatched. At least 256 eggs were laid in 80 nests, of which at least 106 hatched. There are currently 99 chicks alive, three of which are being treated at the Dunedin Wildlife Hospital for various health problems. The oldest chick, Tīwhiri-A1-2026, is 46-days old and weighs 1.8 kg, while the youngest chick, Awarua-A3-2026, weighs 26 grams at 2-days old. Operations manager Deidre Vercoe says that preliminary sexing results show that about 40 percent of the chicks are female, and that rangers are starting to give the older chicks a permanent microchip for identification.

DOC’s Kākāpō Recovery Programme is thrilled to announce the births of 101 kākāpō chicks, with a few more fertile eggs expected to hatch over the next few days. However, kākāpō conservation is a roller-coaster and seven chicks have died from illness or injury. Auckland Zoo vet Adam Naylor resuscitated one small chick using CPR and timely sutures saved the life of another; both patients recovered well and are back in the nest with their kākāpō mother or foster mother. Scientist Andrew Digby reports that egg fertility was similar on the two main breeding islands, Whenua Hou and Pukenui/Anchor Island, and that artificial insemination has had a significant positive effect, improving the fertility of eggs.
