Croxall et al. describe paradoxes, many of which exist only because of a limited review of available information. Stating that the pale-oecological record shows close correspon-dence between ice cover and the presence of Adélie penguins is correct (1), but claiming this species ’ absence from Antarctica until after the Last Glacial Maximum (LGM) is not supported, particularly by their cited refer-ences [(9, 10) in the Review]. These refer-ences indicate only that the species spread north to the tip of the Antarctic Peninsula during the Little Ice Age (responding to more persistent sea-ice cover) and has since been retreating, especially during this era of rapid
