It has the most southerly breeding distribution of any bird. Pagodroma nivea confusa breeds on the South Sandwich Islands and Géologie Archipelago.

Why do petrels fly so low?
Snow petrels tend to fly low over the water but very high over land to avoid predators such as South Polar skuas. Skuas are major predators, but severe weather conditions, especially heavy snow that blocks nest entrances, may cause adults to abandon their eggs or chicks to starve.
How long does it take for a snow petrel to lay eggs?
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. Snow petrel partners are faithful for life (around 20 years).
