Researchers say they're one step closer to proving the existence of the South Island kokako, long thought to be extinct.
The South Island Kokako Trust issued a five thousand dollar reward for sightings of the bird, but recently doubled that.
More than 50 possible sightings have been reported, and even recordings.
Nigel Babbage, the deputy chair of the South Island Kokako Charitable Trust is confident the South Island kokako, long thought to be extinct, is still alive.
He says they just need photographic proof. "The bird is out there. We just need to definitive evidence."
