Beautiful Blue Ducks at Blue Lake - but there is trouble in paradise

The poster in the hut on the Travers-Sabine trail asked for sightings of rare birds and animals - weka, blue duck (Maori name whio, pronounced 'fee-o'), kea, kaka, black-eyed gecko, rock wren. Being observant trampers, it was with high hopes we set off to record sightings. The rushing mountain streams seemed a likely place for whio.  After three days and not a whio whistle, we came to Blue Lake or Rotomairewhenua (land of peaceful waters), surely the highlight of any tramp in this area.
