Apsley Cherry-Garrard was a survivor of Robert Falcon Scott's ill-fated British Antarctic Expedition of 1910, and he documented details of penguin behaviour in his book "The Worst Journey in the World". "They are extraordinarily like children, these little people of the Antarctic world, either like children or like old men, full of their own importance." George Murray Levick, a Royal Navy surgeon-lieutenant and scientist who also accompanied Scott, commented on displays of selfishness among the penguins during his surveying in the Antarctic:"At the place where they most often went in [the water], a long terrace of ice about six feet in height ran for some hundreds of yards along the edge of the water, and here, just as on the sea-ice, crowds would stand near the brink. When they had succeeded in pushing one of their number over, all would crane their necks over the edge, and when they saw the pioneer safe in the water, the rest followed."
