Two stationary yellow-eyed penguins standing sentinel over Sandfly Bay on Otago Peninsula have been confusing penguins, tourists and volunteers alike.
The plywood penguins are so realistic volunteers have rung the Department of Conservation concerned about their welfare, tourists have mistaken them for the real thing and penguins cuddle up to them as if one of their own.
"Penguins have walked up to them, pecked their faces or given them a whack. Tourists have gone home with photos of them," Doc ranger Mel Young says.
The decoys will be appearing on banks of beaches along Otago's coast in an effort to encourage penguins ashore and show them the way to the breeding areas.
It was an initiative used in North Otago in the 1980s and 1990s and had helped its colony go from just a few breeding pairs to 62 last season.
