First wild kakī chick to hatch this season raises hope

The first wild kakī/black stilt chick has emerged from its shell and raises hope after a disappointing start to the 2011 breeding season.

“With the hatching of this wild chick it is now starting to feel like the breeding season is underway. It has been a very late start. The first wild eggs would normally be hatching in October,” explained Liz Brown, DOC Aviculturist.

“We are also down on the number of eggs we are incubating this year at our Captive Breeding Centre in Twizel. We have 30 eggs currently incubating compared with a consistent tally of around 60 eggs over previous seasons,” states Liz.

“The captive birds have been laying later than normal both in Twizel and at Isaacs Wildlife Trust in Christchurch.”

A decline in nesting behaviour seems to be a general trend amongst all braided river birds this year. The region experienced snow in mid October which caused desertion of some nests. This was then followed by floods shortly after which delays re-nesting.

Every spring, native river birds flock to braided rivers to breed.

“From early September until late January those out enjoying braided rivers are asked to be considerate of our fragile nesting birds,” says Liz.

“They nest on the ground and can be very hard to see, especially from a 4WD vehicle. It is better for the birds welfare if you walk to your favourite angling spot rather than drive.”

“Birds that are swooping, circling or calling loudly probably have nests nearby. Move away so that they can return to their nests and look after their chicks.”

The wild egg was collected by Department of Conservation rangers from a pair of adult kakī nesting on braided river gravels. It has taken 25 days to hatch. More eggs collected from the wild are expected to hatch within a few days.

Background information

Kakī/Black Stilts are one of the rarest waders in the world. Threat classification is nationally critical.

Kakī were once common throughout New Zealand, now mostly found in Mackenzie/Waitaki basins

Other riverbed birds migrate in winter, kakī will stay in the braided rivers of Canterbury/North Otago high country and forage for food

Main threat to the population is predation by feral cats, stoats, weasels and ferrets. Hedgehogs will eat eggs.

Wild population was reduced to only 23 birds in 1981. In August 2011 the wild population was approx 170 birds.

Six adult breeding pairs are held in captivity. Four pairs are held in Twizel at the Captive Breeding Centre. Two pairs are held in Christchurch at the Isaacs Wildlife Trust.

Desperately cold wild fantails have made a nest of a South Canterbury home as the polar storm sweeping the country takes a huge toll on our birdlife.

Experts expect millions of birds to die as a result of the polar blast covering the country.

For Doug Sail in Hunter, 40 kilometres south of Timaru, the warmth of his dryer drew in three frozen fantails and he unwittingly saved their lives.

“I noticed them flying around the back door trying to get in. Occasionally they tried to fly in through the window and hit the glass.

“I needed to let the room air out and when I left the door open, all of a sudden there they were – three of them.”

He said the chilly birds made themselves quite at home and remained for about five hours.

“You couldn’t shoo them out, they wouldn’t go out through the open door.”

They were so determined to stay that when he shut the door to get them out, the birds simply found another way in.

“They flew in through the open toilet window. Then, thinking they were just cold, we decided to leave them”

As the creatures huddled together for warmth, Doug and his wife Emily Gilbert took photos and videos.

“It’s something I’ve never seen before. I was surprised at how tame they were.

“When my wife was taking a video clip of them, one of them landed on her camera while she was filming.”
