This area is known to attract ferrets, stoats, weasels, rats, mice and occasionally possums, which prey on the birds and their eggs.
Barry is using a ground-breaking trap developed by NZ Autotraps. The trap resets and rebaits itself, improving the kill rate.
"The great thing about these traps is that they aren't labour intensive and they kill a range of predator species," said the Tikokino Young Farmers member.
"Being smart about where you plant your winter crops and how you feed them can lead to a big reduction in sediment runoff."
"It can often be as simple as putting up a back fence or using a portable water trough to help reduce soil damage," he said.

Grazing sections of crop growing near waterways or at the bottom of slopes last helps trap suspended contaminants.
About 50 of the business' staff are involved with feeding out to cows and young stock over the winter and shifting crop fences.
Two full-time fencers have also been employed to fence off small ephemeral drains.
"Legally we don't need to fence them off. But they're areas that get wet and boggy in winter and if we reduce the number of cows walking through them, that can have a significant impact on water quality," he said.
The majority of the farms sit in the Tukipo River catchment, which has poor water quality.
"The river doesn't have the benefit of a large volume of fresh water flowing through it. It's fed by springs on surrounding farmland," he said.
"Anything we can do to keep livestock out of those springs will make a difference."
Green-thumbed students at the local school are helping to grow native plants and trees for the newly-protected areas.
BEL Group chipped in $4000 to help the school extend its shade house, which can now produce 1000 riparian plants a year.

The farmer-led community group is focused on improving water quality, biodiversity, and their greenhouse gas footprint.
"This year through the group I have applied for and received $32,000 worth of funding from Fonterra to purchase water testing kits and to find potential wetland sites," he said.
Barry and his wife Alison were finalists in the 2018 Balance Farm Environment Awards for East Coast winning the Predator Free 2050 and DairyNZ Sustainable Farming Award.
Earlier this month, he was elected to the NZ Young Farmers Board.
"I have been thinking about standing for the board for the last two years," said Barry.
"To be elected and have the backing and support of my fellow members is an awesome feeling. I'm really happy."
Nine people were vying for two positions in the hotly-contested election.
Barry saw joining the NZ Young Farmers Board as a unique opportunity for a young person to obtain governance experience.
