They don’t ward off storms, or flee them, they climb aboard and trip them. The meteorology of the Southern Ocean is so severe that the sector may perhaps quite be considered as basically one huge, immense, unending typhoon. For any non-aquatic animal, this attribute makes the Southern Ocean approximately as inhospitable because the polar wastes or the main severe of deserts. To all however the albatross, that is.This paintings outlines the lifestyles histories of those awesome birds, and explores a number of the major techniques and strategies that experience advanced to permit them to accomplish mastery of 1 of the main adverse areas on this planet.

Anatomically, their strikingly different tongues hint at very different feeding behaviour, although it remains unknown what those differences might be. Scant data available suggest they may be more active hunters rather than scavengers like other albatrosses. Although their distributions broadly overlap, the sooty albatross is most numerous north of the Antarctic Convergence whereas the light-mantled albatross is most numerous south of that boundary. In fact the lightmantled is the only albatross to commonly penetrate the region of pack-ice fringing the Antarctic continent itself.

On the reasonable assumption that albatrosses land on the water only to seize prey, such an exercise quickly amasses a persuasive body of evidence addressing the question of whether the birds focus their foraging activity at night or during the day. One of the earlier exponents of this approach were Patricia Fernández and David Anderson, who in 2000 published their findings involving trials with Laysan and black-footed albatrosses in Hawaii. In this preliminary exercise they retrieved useful records from six black-footed albatrosses and seven Laysan albatrosses on foraging trips lasting an average of about three days each.

Put these two factors together, and the result (notwithstanding the somewhat less than temperate weather) is a veritable storm of life. This is especially true for birds. Huge numbers of penguins, cormorants, petrels, shearwaters, skuas and other birds breed at most of the islands scattered across the Southern Ocean. However, most of these are more or less confined to the immediate neighbourhood of their rocky refuges. Only one bird can truly be said to have fully unlocked the resources of the Southern Ocean, due largely to the way it has evolved to deal successfully with the most ferocious winds on the planet.
