[00:00.000]At the southern end of our planet
[00:02.667]fiery ribbons are illuminating the winter skies.
[00:06.666]The aurora australis.
[00:09.413]This light brings no warmth to the male penguins
[00:14.908]who are still huddling
[00:16.167]defying the coldest conditions on the planet.
[00:19.916]Their ordeal is drawing to a close.
[00:24.664]30 days after it last set
[00:28.416]the sun rises once more on Antarctica.
[00:32.909]Their appalling trials have all been for this.
[00:38.157]Each father has just one meal left inside him. He's been saving it all winter.
[00:46.916]This single feed will sustain the chicks for a few more days
[00:53.164]but the males have not eaten for nearly four months.
[00:57.421]If they do not eat soon
[00:59.159]they and their chicks will die.
