Camera crews discovered a colony of Adélie penguins while filming on King George Island, some 750 miles south of the Falkland Islands.
The programme is being presented by ex-Monty Python star Terry Jones, who said: "We'd been watching the penguins and filming them for days, without a hint of what was to come.

"But then the weather took a turn for the worse. It was quite amazing. Rather than getting together in a huddle to protect themselves from the cold, they did something quite unexpected, that no other penguins can do."
BBC1 viewers will see the penguins not only take flight from the Antarctic wastes, but fly thousands of miles to the Amazonian rainforest to find winter sun.

"The film reveals nature's stunning glory in exciting and unexpected ways, so much so that it defies belief," said Mr Jones.
