Non-breeding movements of Gentoo Penguins at the Falkland Islands
Although many penguin species migrate during the non-breeding period, Gentoo Penguins Pygoscelis papua are year-round residents. Despite being characterized as inshore feeders, the at-sea spatial usage of Gentoo Penguins during the non-breeding period, when central place foraging constraints are rel...
