Birds Buldir are shown in red (n = 5), birds from St. George are divided into a northern (n = 11, shown in dark blue) and a southern (n = 17, shown in light blue) group; arrows indicate breeding colony locations. Shaded polygons show 50% UD; empty polygons show 95% UDs. Arrows indicate the locations of breeding colonies at Buldir (red) and St. George (blue). BA values represent amount of overlap (out of a maximum of 0.5) in 50% UDs between the three groups.
