Although young and still new to the job, kiwi dog Fen is showing flair for finding kiwi, surprising Nelson Lakes Department of Conservation staff with a new kiwi chick.
The kiwi chick is the fifth known to have hatched in the wild in Nelson Lakes National Park's Rotoiti Nature Recovery Project since great spotted kiwi/roroa were reintroduced there six years ago as part of BNZ Save the Kiwi.
Tracking kiwi scent, Fen led DOC rangers to a burrow where, to their amazement and delight, they found the chick with its parents. The chick is believed to be about seven-months-old.
"The chick was a complete surprise," said DOC ranger Nik Joice. "We weren't expecting to find a chick as we didn't think any had hatched over the last breeding season."
"Discovering chicks bred in the wild is significant as it is a good sign a breeding great spotted kiwi population can be successfully re-established in the Rotoiti Nature Recovery Project."
Nik said DOC staff were very pleased with the aptitude Fen, a two-year-old short-haired German pointer, was showing as a newly-trained kiwi dog. As well as locating the chick, his kiwi-seeking skills also helpfully tracked down two adults that had lost their transmitters that day. One was the chick's father, Onahau. This enabled DOC rangers to put on new transmitters to continue tracking their movements.
"Fen's doing really well for such a young dog and he is obedient which makes him very good to work with," said Nik.
The Rotoiti kiwi population includes two other chicks, around seven months old, that are now over 1kg in weight - large enough to fend off attacks from stoats.
The two are among three that in March were the first BNZ Operation Nest EggTM chicks brought in to boost the kiwi population. They had been taken as eggs from Kahurangi National Park and hatched at Christchurch's Willowbank Wildlife Reserve before going to the Rotoiti project area where intensive pest control is carried out over 5000 hectares to protect native species.
The third chick was found dead 11 days after its arrival at Rotoiti and is thought to have died as a result of illness, though pathology tests have been unable to confirm what had caused its ill-health.
"It was sad to lose the chick, but importantly it had no apparent signs of predation," said Nik.
"The main risk to the chicks had been stoat predation, but the fact none have fallen victim to stoats indicates our trapping may be sufficient to protect chicks on their own without parents. "
The Rotoiti Nature Recovery Project kiwi population is now 22. It includes 15 adults moved to the area from Kahurangi National Park, five young kiwi known to have hatched in the project area, and the two BNZ Operation Nest EggTM chicks.
