I’ve recently returned from Codfish Island/Whenua Hou where I spent a week helping rangers from DOC’s Kākāpō Recovery team. While I was there I was lucky enough to experience the hatching of the first kākāpō chick of the season.

The journey to Codfish Island began with my first ever ride in a helicopter. As the chopper flew over Foveaux Strait I could almost hear the Jurassic Park soundtrack playing in my head. We were heading to the New Zealand equivalent of a ‘land before time’.

Upon arriving on the island it truly did feel like I had been transported to another era. Birds, bats, lizards and insects ruled the island, and the small hut just off the main beach at Sealer’s Bay, seemed to be an oddity in such a wild and ancient place.

The island is home to most of the surviving population of kākāpō in the world, and was teeming with kākā, kākāriki, korimako, mōhua and the Codfish Island mātātā.

The diversity of plants at different points on the island was stunning; I had never before seen such lush plant life and native bush. The local korimako/bellbirds were by far the friendliest native inhabitants of these bushes and they were not afraid to land right at your feet and check you out before returning back to the bushes alongside the tracks.

The curiosity of the bellbirds was only rivalled by that of a kākā called George who loved getting his beak into anything that was left lying around the hut. He was even blamed for one or two items of clothes that went missing from the washing line.

Having grown up in the North Island I had never before seen a mōhua/yellowhead. This beautiful little bird was last year crowned New Zealand’s Bird of the Year so I really hoped I would get to see one during my stay. Not only did I get to see one, but I discovered they are social creatures and groups of them could be seen flitting from branch to branch and singing from the treetops.

At night the short-tailed bats took over the island. Unlike other bats they use their folded wings as limbs to scramble around on the ground to search for food, if you are walking around the island at night you have to be careful where you step.

The booming and chinging of the male kākāpō can be heard all over the island at night. One evening, as we were transporting gear from one of the kākāpō nest sites, we ran into Wolf the kākāpō booming his little heart out just off the track. If you’ve never heard a kākāpō boom before it’s quite an unusual sound. Not only do you hear it but you can also feel the vibrations go right through you.

DOC’s ensures the kākāpō are well looked after and protected from pests and diseases. Quarantine on the island is strict. Diseases and pests could do real harm to the remaining kākāpō population and the other species that call Codfish Island home.

While on the island one female kākāpō needed to be caught for a health check. Transmitters make finding the kākāpō a reasonably easy job, although catching them isn’t always as simple. Sometimes the kākāpō might be sleeping up in a tree or tucked away on the forest floor. These are wild animals, so they don’t take kindly to human intrusion. In this case the kākāpō was easily found and caught and the health check turned out to be a quick and painless affair.

Perfect weather for young albatross chicks

Summer in Dunedin didn’t seem to stay around for long this year, but I wasn’t complaining. Unlike most years, where fly strike leads to the loss of young albatross chicks, we had such mild weather over the hatching period that no fly strike occurred.

Last season we had 26 chicks fledge. We are hopeful that the 24 chicks on the headland this season will all fledge, making a nice round 50 fledglings in two years.

Seven years abroad: Pukekura’s 500th royal albatross returns

After seven years abroad, the 500th royal albatross chick to have hatched at Taiaroa Head/Pukekura, has finally returned home.

Toroa, the 500th royal albatross chick.

Toroa, and two other chicks, had transmitters attached to their back feathers when they fledged in 2007.

All three survived their long journey at sea for the first year, after which the transmitters stopped sending back signals. It has been a long wait to see if any of these birds would return.

Toroa, the grandson of ‘Grandma’—the colony’s oldest bird (over 60 years old when last seen in 1989)—arrived home to find his own parents breeding again.

The image below shows Toroa with a two-month old sibling. This chick is on its nest close to where Toroa himself was raised.

Toroa has been hanging around this same area not because of any bond with his sibling or his parent (there is no interaction between parents and returned chicks), but because he, like most males, will nest fairly close to the site where he was raised as a chick. Nest sites tend to be closer to the male hatch site than to the females hatch site.

Scurvy explosion

Cook’s scurvy grass (Lepidium oleraceum) has had a population explosion here at Taiaroa Head/Pukekura.

Just three plants of this threatened species (once abundant and used by Captain Cook to help reduce the effects of scurvy) were on Pukekura last year.

Now, nestled in among the 2000 pairs of red-billed gulls (that produced plenty of quality fertilizer), this species numbers over 40 large healthy plants.

The ice plant in the background of the image above is South African, and was probably introduced onto the headland to help hide the stone and concrete gun emplacements used during the Russian Scare of the late 1880’s.

Interestingly, the ice plant can not tolerate the excreta from gulls and dies back, whereas gull excreta doesn’t affect the native ice plant found in the same area.

Planting for penguins

The Pukekura Trust little penguin colony at Pilots Beach has recently benefited from Air New Zealand Environmental Trust funding.

This allowed several hundred new natives to be planted—mostly by school children—throughout the reserve.

You can see part of the little penguin viewing platform in the image above. Here, at dusk, as many as 300 little penguins waddle in from the sea.

Plans for a new marine reserve, whale and fur seal sanctuary, five customary fishing areas and amateur fishing regulations for Kaikoura’s coast and ocean were announced over the weekend.

This area is the most biologically rich ocean over 500 metres deep anywhere in the world, because of its deep canyon so close to shore.

It is hoped that these new marine protections and management tools will be in place by 2015.

I’ve just come back from spending a week on Codfish Island/Whenua Hou down by Stewart Island helping the Kākāpō Recovery Team with the important work they do to look after those mossy green parrots.

With only 126 kākāpō in the world every chick counts, so imagine how stoked I was to be able to witness the hatching of the first kākāpō chick for the 2014 breeding season. Hopefully there could be up to six new kākāpō chicks by the end of this season.

I arrived in the deep south to news that the egg that was due to hatch had been accidentally crushed by kākāpō mum-to-be Lisa. The kākāpō rangers had been monitoring the nest and were able to swiftly rescue the egg and, thanks to some quick thinking and some good old-fashioned ‘kiwi ingenuity’ from ranger Jo Ledington, the egg was carefully repaired with some glue and tape.

The condition of the bird inside the egg wasn’t known, but everyone crossed their fingers and hoped that this little chick would be a fighter.

The day I flew into Codfish Island the chick could be heard pipping inside the egg. This was a big relief to know that the chick was alive and almost ready to hatch.

After dinner kākāpō ‘surrogate mum’ Darryl Eason ran in to tell us that the chick was starting to hatch.

Luckily the chick managed to find an exit from the egg avoiding the tape and hatching out the other side. It was a frail looking bundle of fluff, but it was in a good condition. It was a fantastic experience to be in the room as the newest kākāpō entered into the world.

Welcome to the world little one

It can take a while before the sex of the kākāpō can be determined, so for now this little was is known simply as ‘Lisa One’.

The wee chick will be returned to a nest when it is healthy and strong. To give the chick the best start in life it may not go back to its biological mother Lisa, instead the rangers monitor potential foster mothers to ensure that the best mum is given the chance to raise a chick.

Kia kaha little kākāpō, it was great to experience your hatch day with you and I can’t wait for further updates from the kākāpō team.
