A series of programmes featuring natural history films from other countries.
In 1936 Lance Richdale began a remarkable study of the yellow-eyed penguins of New Zealand's Otago Peninsula. Richdale's study was to last him 18 years - focusing on individuals rather than populations.
In time he gave a number to every bird, and a name to each colony. But in Colony Z there was an old male penguin who was to become better known to him than all the others, he was Z12.
This film by NZTV is a recreation of Richdale's life in the summer of 1940 as he followed the fortunes of Z12 and his mate Z115 in their final season together.
