In short, the meteorology of the Southern Ocean is so extreme that the region might reasonably be viewed as essentially one enormous, endless storm. One with random patches and periods of relative calm, true – but broadly speaking Antarctica is ringed by an eternal torrent of high-velocity air. This abundance of high-velocity air in the Southern Ocean and the rotating nature of weather disturbances together offer a potential ‘transport system’, in any direction needed, to any seabird that can evolve the physical and behavioural means to exploit it.
However, a surprising body of indirect evidence can be marshalled to illuminate the question. For example, there is at least one record of a wandering albatross actually seen to kill and eat a squid about 40 centimetres long, which would probably have weighed around 500 grams. Suppose we tentatively take 500 grams as the upper limit at which albatrosses can successfully capture living squid, and see where that takes us. This figure may not be implausible: in 50 Food and foraging their study of the diet of the much smaller grey-headed albatrosses, for example, N.
Also, a fact that we are all familiar with, in summer the day length increases steadily towards the poles, which means that polar regions receive nearly constant sunlight for several months of every year. 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.
