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...
