Archives For black stilt

By Kiersten McKinley

Assistance from private land owners helped create a record breeding season for the nationally critical threatened kakī/black stilt this year, but not before giving DOC’s Twizel staff the run around.

Each year rangers collect kakī eggs from the wild, and up to six captive pairs, for safe incubation at the Captive Breeding Centre in Twizel.

Last spring, when it came time to find nests in the normal riverbed and wetland sites, staff couldn’t find many. Either the population had declined or they had nested elsewhere. Luckily it was the latter: A particular rainy start to the season saw many wet areas and ponds form on private land. These made attractive nesting sites for this threatened wading bird.

“We put the word out that we needed help to locate adult breeding pairs and got a fantastic response. We had one farmer who rang up to say he had found four eggs and he’d wait until we picked them up before moving his sheep into the paddock,” said Biodiversity Ranger Simone Cleland.

“Another farmer spotted a likely nest from the seat of his tractor. He called up straight away so that we could rescue the eggs and he could carry on working!”

“The farmers I dealt with were very in-tune with their environment and knew exactly what birds they were looking at,” said Biodiversity Ranger Cody Thyne.

“Some people have trouble distinguishing kakī from pied stilts or even oystercatchers,  but these farmers were extremely observant and reliable informants.”

It wasn’t only farmers that responded to DOC’s request for help. Sam Staley, the caretaker stationed at Lake Tekapo Military Camp, rang up on several occasions during the season to report the location of juvenile kakī.

Soon the eggs were rolling in; 172 all up, and that put extra pressure on Aviculturist Liz Brown and her team at the captive rearing centre.

“We managed to successfully incubate and hatch 134 chicks, of which 125 survived to fledge – well up on our previous best of 111,” says Liz.

Nearly half of all the wild eggs collected over summer came from eight high country stations in the Mackenzie and Waitaki basins. And, while we’ve always had good ongoing communication with these landowners, the cooperation this season has been excellent and we hope to maintain and develop this relationship in the future.

31 of the chicks were released near Tekapo in January, as the capacity of the aviaries to hold birds had been reached. The remainder of the young kakī will be held over winter and released in August this year. If they can survive the first few years then rangers may be collecting their eggs in the future too.

After 39 years working in conservation, Dave Murray retired at the end of February from the Te Manahuna Area Office in Twizel. A sociable character, you always knew when Dave was in the room! His lively presence will be missed in the office.

Dave spent the last 30 years working with critically endangered kakī in the Mackenzie Basin. Over this time he developed a huge depth of knowledge on New Zealand’s unique braided rivers, having worked within all major riverbeds from Godley river in the north, to Ahuriri river in the south.

Name: Dave Murray.

Job position: Ranger – Assets-biodiversity, Te Manahuna Area office, Twizel.

How did you get into conservation work?

I started off working for the New Zealand Wildlife Service. The job was very diverse and I was one of the last people to get a job without a degree or the internal traineeship. There were only 200 employees in the Wildlife Service working in the field so you knew everyone—you could ring anybody for advice. It was far less formal, and more relaxed than DOC. There was not much money and you had to do everything on a shoestring.

I spent some time in Rotorua doing law enforcement work and then moved to the West Coast. I spent several years carrying out bird and vegetation counts in the beech forest. We worked from Westport through to Okarito, concentrating on areas that were likely to be involved in logging.

What was your role with DOC?

After a stint as the sole Wildlife Service officer in Hokitika, I was asked to come and look after the kakī/black stilts in Twizel in 1981. Since that time I have seen the kakī numbers slowly increase. Kakī would have been extinct by now if we hadn’t been doing what we have been doing.

How did the Kakī Recovery Programme get started?

In 1981 there were only 23 kakī left. Ron Neilson was working for the New Zealand Wildlife Service in Dunedin and he came up and realised there were not many kakī. Also, Ray Pierce was doing a thesis at Otago University on black stilts and pied stilts and he figured out that between the two species, there were not many left.

Have you any thoughts on preservation of our braided rivers and wildlife?

How do people use riverbeds without stuffing them up? It would be good to fence off riverbeds and allow people to walk around them and not be able to drive. I‘ve seen a huge increase in the number of 4WDs in riverbeds over the years. I have also seen people park in the middle of black-fronted tern colonies to go fishing and wonder why the birds are annoying them.

What was the best part of your job?

Walking the river deltas on calm, clear days in winter… then spotting banded kakī that I knew and seeing them survive in winter—it’s pretty encouraging.

What is your favourite place?

Okarito on the West Coastis a place that is special to me.

What are your plans now?

I’ve got a lot of images to categorise. I’d also like to photograph new stuff—I have just been photographing saddlebacks and stitchbirds. I take pictures of birds doing things, I don’t like posed pictures.
