The wind was strong, but the sun was shining as the first 19 juvenile kaki/black stilt were released onto the Tasman River last week.

Fingers went numb and noses turned bright red as DOC staff caught kakī/black stilts this morning. It was the first fine day after a southerly blast and the birds were off on an adventure!
Nine staff were needed to catch 43 sub-adult kakī from the Captive Breeding Centre aviaries located in Twizel. The birds were being released today into the Tasman Riverbed near Lake Pukaki – but first they had to be caught!
Armed with large soft nets and a slow, purposeful stride each ranger waited patiently for a young bird to rest on the aviary floor. It’s unhurried and cautious work – one fast or sudden move and these fragile birds could end up with a serious injury. Some of the birds managed to get their bills poked through the soft capture nets so another ranger was flagged to assist in the delicate extraction operation. The long, slender bill of a kakī actually has tiny, fine serrations on it which makes it fabulous for getting caught in nets!
Once caught each bird underwent a thorough health check and was carefully weighed. A sub-adult bird is nine months of age and the majority of birds weighed around 200 grams – less than half a tub of margarine! What they lack in weight though they more than make up for in spirit. These are feisty birds and they were certainly ready to spread their wings!
All the kakī were placed into sturdy plywood boxes and then transported to the release site where they were set free by local school children and interested members of the public.
Take part in a kakī release:
Two kakī releases are scheduled every year around August or September. If you would like to attend the next one email DOC Ranger Cody Thyne. It’s a wonderful experience and a chance to see these rare birds up close.

At work
Some things I do in my job include… trapping cats and mustelids etc. As time allows I get involved with electric fishing, kaki (black stilt) work, and anything else I can help with.
The best bit about my job is… working outdoors with views of Mt Cook, and the variety my role allows.
The funniest DOC moment I’ve had so far is… when I was in a hurry to get a block of traps checked ahead of the forecasted snow later that evening and the quad bike became stuck. And when I say stuck I mean it took me five hours of digging to get out. I kept myself motivated with the thought of avoiding the dreaded office shout and the shame that goes with it. What I didn’t know at the time was that my workmate trapping in the next block had got his quad stuck as well, but had to abandon it as there was no way he could dig it out on his own, so had legged it back to the truck. I guess you could say it was just one of those days. The upside was the forecasted snow never came so we were able to winch out his quad the next day.
The DOC (or previous DOC) employee that inspires or enthuses me most is… as I haven’t been with the department for that long I am yet to meet this person.
On a personal note…
The song that always cheers me up is… definitely Bob Marley “Three Little Birds”.
My best ever holiday was… recently when my partner Melanie and I travelled to Canada, Austria, Germany, Italy, Denmark, England, France, and for the grand finale, two days at Disney Land, LA. I’m still in that place where you think about it every day and smile. It was such an awesome experience that I can’t wait to travel again.
My greatest sporting moment was when… I ran the length of the field side stepping and fending off players to score under the posts in a high school rugby match at the tender age of 14. When I walked off the field at the end of the game, one of the 1st fifteen boys said, “You looked like John Kirwan the way you scored that try”. I was stoked.

Changing a GPS tracking collar on a feral cat. I play the role of chief cat wrestler, which has it’s share of exciting moments
In my spare time I… have just started down the long road of becoming a “Master bow hunter”. I am now consumed by how many game points I need to gain the next award. I see animals as points (rabbit 2, hare 5). You are probably thinking ‘Is this an illness?’ The short answer is yes. Damn you Rhys Garside! Lol.
If I could be any New Zealand native species I’d be… a Falcon, without question…. Just think: no boundaries, total freedom. That’s what I’m talking about.
