Kernel density distribution (20, 40, 60, and 80%) of dive locations. Kernel density distribution shows the places where the Gentoo Penguins Pygoscelis papua spent most of their forging time, for birds breeding at the North End (shades of red) and South End (shades of blue) colonies, New Island (in black), Falkland Islands / Islas Malvinas. Depth zones (in m) are based on data from the Global Topography (Smith & Sandwell 1997) and an IDW interpolation in ArcGIS 9.3. Only dives performed during the first foraging trip of each individual were included
