A threatened bird species in New Zealand is fighting its way back from the brink of extinction.
The great crested grebe is grabbing its chance of survival thanks to swim noodles and some good old Kiwi ingenuity.
Three years ago there was only one pair of great crested grebes in Wanaka, desperately trying to make a floating nest.
They had built nests, they laid eggs, and they lost them, twice over.
Luckily for them, retired zoologist John Darby noticed their plight and set out to build them their own pontoons.
"It was very important to build them a nest, and so I built the first nest, but I didn't just build ordinary nests," he said.
"I built super big nests... and they seemed to go for that in a big way."
The great crested grebes are one of New Zealand's rarest birds.
It's estimated there are only 600 in the wild.
Mr Darby has a concession from the Department of Conservation to trial the nest pontoons.
He hopes to establish a grebe reserve alongside the marina.
