In 1947, in an attempt to assess how long rookeries could withstand such losses, the Fauna Board of Tasmania joined forces with CSIRO to investigate the mutton bird''s life history. The bird''s fantastic migration was one of the most interesting facts they uncovered. The huge flocks that cross the Pacific each year to spend the northern summer in Canada and Alaska, return to their Bass Strait breeding grounds on almost the same day each year.
Produced in 1956.
