context_page_description: The southern giant petrel, also known as the Antarctic giant petrel, giant fulmar, stinker, and stinkpot, is a large seabird of the southern oceans. Its distribution overlaps broadly with the similar northern giant petrel, though it overall is centered slightly further south. Adults of the two species can be distinguished by the colour of their bill-tip: greenish in the southern and reddish in the northern.
context_section_description: The southern giant petrel achieves sexual maturity at six or seven years of age; however the average age of first breeding is ten years. Its breeding season begins in October. Its nest is a mound of moss, grass, and stones with a depression in the centre and is located on bare or grassy ground. They form loose colonies except in the Falkland Islands where the colonies are much larger.
  One immaculate white egg that is 103 by 70 millimetres (4.1 by 2.8 in) is laid. It is incubated for 55–66 days, where it is always guarded by at least one of the parents. When the white chick is born it is brooded for two to three weeks and it fledges at 104–132 days.
