A series of programmes featuring natural history films from other countries. Colony Z
In 1936 an unknown schoolteacher Lance Richdale began a remarkable study of the yellow-eyed penguins of New Zealand's Otago Peninsula. Richdale's study lasted for 18 years. In time he gave a number to every bird, and a name to each colony. But in Colony Z 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 re-creation of Richdale's life as he follows the fortunes of Z12 and his mate Z115 in their final season together. (R)
