Very nicely observed, Ron. All the photos (except the first) are identifiable to the small town of Whataroa (pop 400 or so), which is close to the Okarito lagoon, the only place in NZ where the rare white heron breed. There are only about 150-200 white herons, although numbers seem stable. Whataroa is about 3/4 the way between Hokitika and the Franz Josef glacier.
