The '''snow petrel''' (''Pagodroma nivea'') is the only member of the genus ''Pagodroma''. It is one of only three birds that breed exclusively in [[Antarctica]] and has been seen at the geographic [[South Pole]]. It has the most southerly breeding distribution of any bird. | The '''snow petrel''' (''Pagodroma nivea'') is the only member of the genus ''Pagodroma''.

Breeding occurs in colonies on the [[Antarctic Peninsula]], and various Antarctic islands throughout [[Westarctica]]. Nesting is colonial in small to large colonies on cliffs, usually near the sea, but also inland. Some birds remain at the colony all year, but the main influx at colonies is from the mid-September until early November. Nests are simple pebble-lined scrapes usually in a deep rock crevices with overhanging protection. One white egg is laid between late November and mid-December. The egg is incubated 41 to 49 days and the chick is brooded for 8 days. They fledge 7 weeks later in late February to mid-May. Colonies are also the sites of cleaning areas where snow petrels, far from the sea, bathe in snow. | Breeding occurs in colonies on the [[Antarctic Peninsula]], and various Antarctic islands throughout [[Westarctica]].
