The cliff tops are soon stained pink |
| [00:03.70] |
with the droppings of tens of thousands of nesting penguins |
| [00:08.62] |
Only in a land almost entirely covered in ice |
| [00:13.4] |
could bare rock be reckoned an oasis |
| [00:18.6] |
Some will travel into the heart of the continent to find it |
| [00:23.78] |
These are nunataks |
| [00:27.64] |
the exposed peaks of vast mountain ranges |
| [00:31.14] |
buried in ice over a mile deep |
| [00:36.26] |
The eerie silence here is only broken in spring |
| [00:41.87] |
The snow petrels have arrived and are courting |
| [00:46.97] |
Antarctic petrels now join |
| [00:48.49] |
the most southerly bird colony on earth |
| [00:54.14] |
The birds have flown inland for over 300 miles |
| [00:57.86] |
to reach this breeding site |
| [01:00.26] |
Once their eggs have hatched |
| [01:02.10] |
they'll be forced repeatedly to make the 600-mile round trip |
| [01:06.48] |
to gather food in the ocean |
