On a misty Thursday morning last week I headed out to the Kawhaka Creek to help retrieve eggs from two whio / blue duck nests.
The newly established West Coast Wilderness Cycle Trail follows alongside this beautiful river and makes access to the site easy.
The Kawhaka Creek is good for whio. It’s fast flowing, clean—with plenty of invertebrates for whio to eat—and has good habitat either side for nesting. I myself have enjoyed plenty of nice swims in this creek.
It’s a bit of a walk with the incubator to the nest—definitely a job for two people—especially on the return trip when we want a smooth ride for the precious eggs.
This is the first time ever that whio eggs have been taken from this site.
In 2012 Kawhaka Creek was added to the Central West Coast Whio Recovery Site. The support of Genesis let us grow this site, that was initially made possible with support from Solid Energy. The Central West Coast Whio Recovery Site now includes the Styx, Arahura, Taipo and Kawhaka catchments.
The first nest at Kawhaka Creek was found a couple of weeks ago by Cloud the whio dog.
The nest was quite a way up a hill beside the river—a good place for a nest as it was out of the reach of floods. In a forest, on a hill, did seem to be a peculiar place to see a duck though. However, I am assured this is quite normal for whio.
Ranger Ron Van Mierlo had to stretch his arm quite a way down a hole to retrieve the eggs.
It was exciting to see the eggs being retrieved, and a bit nerve-raking too—nobody wants to drop and egg, and the utmost care is taken.
We found 6 eggs at this first nest. I thought 6 was an epic effort, but apparently nests with up to 9 eggs are found!
There is a good chance that the duck who laid those eggs will now lay another clutch this season. In this way, whio breeding can be “supercharged”—the duck lays more eggs that can be successfully raised into adulthood.
After the first nest we were feeling very chirpy—what a great start to the morning.
The next nest was located further up and across the river. We located the nest but, unfortunately, it was empty. The nest had been raided by some sort of predator. The mother duck was still hanging around the nest, on the other side of the pond. Here she is on her lonesome. Hopefully she will lay some more eggs and we will be able to safely retrieve them.
After a commute to Christchurch, the eggs were taken to the Isaac Conservation and Wildlife Trust, a privately funded charitable trust specialising in captive breeding and release of endangered species.
Hopefully, all going well, these eggs will all end up as strong healthy whio that will be returned the wild and in turn lead to even more whio!
The Central North Island DOC Services team is working on an exciting project to bring captive bred whio/blue duck to the Tongariro National Trout Centre near Turangi and to prepare them for life in the wild.
A new whio hardening facility is being opened which will provide a safe environment for young birds from the whio captive breeding programme to develop their white water skills before they are released into the wild.
Construction of the hardening facility began in April and will hopefully be completed by the end of September. The project involves the conversion of an old water raceway into a stretch of fast flowing river complete with rocks and gravel to mimic a natural stream bed.
Young whio need to develop the strength to tackle fast flowing rivers which will be their home in the wild, and this new facility will act as their gymnasium.
The facility will also be a retirement home for some of the older birds that have played an important part in DOC’s breeding programme.
Whio that are too old to breed or to adjust to life in the wild will have a safe home to live out the rest of their lives.
This project is part of the Whio Forever partnership between DOC and Genesis Energy to save New Zealand’s unique whio/blue duck.

Last month we told the story of the Nina Valley ‘Ecoblitz’ — a monumental collaboration involving scientists, senior high school students, university students, teachers, and helpers working together to discover and document the species of North Canterbury’s Nina Valley and surrounds.
Today, we’re happy to report of their recent (earlier this week) success at the Ministry for the Environment Green Ribbon Awards — taking out both the ‘Supreme winner’ and the ‘Communication and education’ awards.
Well done to everyone involved in this inspiring event!
Another exciting Green Ribbon win was the Genesis Energy Whio Recovery Programme, which took out the ‘Protecting our biodiversity’ award.
This five-year partnership between Genesis Energy, DOC, Forest & Bird and the Central North Island Blue Duck Charitable Trust is all about the protection and recovery of whio, which are rarer than some species of kiwi.
By working with Genesis Energy on this programme, we are able to do more work to protect the whio and provide practical and immediate on-the-ground benefits for these threatened birds.
Both these projects show what New Zealanders can achieve by working together to preserve our outstanding natural wealth.
