Locals in south Westland are being told to be on the look out for drunk kereru.
New Zealand's native wood pigeons are getting stuck into a bumper crop of summer fruit, which after sitting in the sun, ferments inside them, and turns into alcohol.
That is leading to some wood pigeons being so drunk they are falling out of trees, the Greymouth Star reports.
The same happened in Whangarei a couple of years ago, and Native Bird Recovery Centre manager Robert Webb says they had to help the pigeons sober up.
In 2010, the sanctuary was inundated with about 60 wood pigeons who'd had too much guava.
He says once it is flushed through their bodies, they come right.
Webb says anyone who sees a pigeon lying on the ground should help it out.
