More info about the #kakapo population milestone here: www.doc.govt.nz/news/media-r.... We won't be naming all of the chicks this year, which is a progression I've been keen on for a while now. #kakapo2026 #conservation

Kākāpō population reaches new milestone
The official population of the critically endangered kākāpō has reached a recovery-era high of 325 birds.

325 #kakapo! The chicks from this year's record breeding season are now juveniles and so have been added to the population. In 1995 there were just 51 kākāpō left. Recovery of critically endangered species _is_ possible with sustained effort. #kakapo2026 #conservation #parrots

With highly-pathogenic avian influenza now in NZ, we're taking steps to protect #kakapo and #takahe by vaccinating against the disease, following a successful trial. We're aiming for ~90 kākāpō and 100 takahē in an initial phase to protect the most valuable birds/sites. #conservation #birds

Bird flu has reached New Zealand – what this means and what comes next
The confirmation of the bird flu virus in a brown skua appears to be a single detection. Ongoing surveillance will be essential to detect any further cases.

The final #kakapo chick (Pearl-4B) from this year's cohort has fledged the nest (defined as roosting outside the nest for the first time). There are 91 chicks alive. They won't be counted towards the population until they're 150 days old. 📸 Petrus Hedman #conservation #kakapo2026 #parrots #birds

This nest wasn't usual: the first ever in which we couldn't access the chick. But Whetu-A3 has recently fledged from the nest in good health. As we transition to less intensive management for #kakapo, more nests will be treated like this (without ramps!). 📸: Petrus Hedman. #conservation

The #kakapo chick Whetu-A3 hatched successfully, but we couldn't weigh it or check its health, and could only look in occasionally to see it was still alive. Worried it might injure itself when it came to fledge, our team built a ramp for it. #kakapo2026 #conservation 📸: Petrus Hedman

Two months ago, I returned a fertile #kakapo egg (Whetu-A3) to the nest and tried to remove another infertile egg from beneath her. She wouldn't let me take the egg, so I offered her the new one. Tricky to do that with one hand while using my phone to see what I was doing! Luckily she took the egg!

My favourite #kakapo nest from this year was Whetu's on Anchor: she was 2m off the ground, 2m down a hollow rata trunk, with an entrance so small we had to use a phone camera to see inside. It was the only nest we didn't get into. #kakapo2026 #conservation #parrots

Sir David Attenborough has a soft spot for #kakapo. We named a kākāpō after him (Attenborough the bird is now ten years old, living on Te Kākahu) and he kindly narrated a short video for us about them, which you can see here: youtu.be/5eZVjQowNvw?.... #attenborough #conservation

Here's #kakapo Rimu's cliff-top entrance. It's a narrow ledge and a long way down, so a very precarious place for a chick to first venture outside! With the chick found inside this nest, the number of chicks alive increased to 93, out of 106 hatched. #kakapo2026 #conservation #birds

Our team has finally managed to dig into #kakapo Rimu's cliff-top nest on Te Kākahu. We knew there was at least one chick inside, and that it had a high chance of falling to its death when it left. The cliff-side hole has been blocked and new entrance made. Pic: Daryl Eason #kakapo2026 #conservation

The 92 living #kakapo chicks are from 29 to 73 days old. The oldest have had transmitters fitted and have fledged (roosted outside the nest during the day). They'll stay with their nest mother for several more months, then will leave once they're 6+ months old. #kakapo2026 #conservation #wildlife

This late into a #kakapo breeding season, long after the mating has finished, a few males will still be at their bowls. They'll be sporadically booming, but most often you'll hear their 'skraaks' as they scrap for territory before returning to their winter ranges. #kakapo2026 #conservation

It is hard to guess, and there’s always the risk of disease causing high mortality. But since 2016, hatch to fledge survival has ranged from 70 - 90%. We’re currently at 90%, so expect we’ll be around the lower end of that range, if not lower. 🤞🏻

This year's #kakapo breeding season has been the biggest on record: - 256 eggs (252 in 2019) - 148 fertile eggs (116 in 2019) - 105 eggs hatched (86 in 2019). It'll be 2+ months until we know how many chicks will fledge (73 in 2019). There are currently 95 alive. #conservation #kakapo2026 #birds

Lots of ripe rimu fruit appearing on the trees on Pukenui/Anchor. This is the food driving the current biggest #kakapo breeding season on record: ripe fruit is the main diet of kākāpō chicks, and a record rimu crop is the reason why the chicks are growing well. #conservation #kakapo2026 #birds
