If you're talking Tichodroma muraria , I can't see it. The beak and toes are too short, the coloring's wrong, the body is slimmer. If it's real, my vote is "unless it's some oriental species we haven't heard of." Or somewhere else in the world. It's not Australian or American, anyway, or I'd recognize it.
But I think it's a figment of the decorator's imagination.
