Birds from Buldir Island (n = 5 in 2016, n = 9 in 2017) are shown in red, birds from St. George Island (n = 29 in 2016, n = 7 in 2017) in blue; arrows indicate breeding colony locations. The 25%, 50%, 75%, and 95% UD levels are shown in progressively lighter shades. BA values represent amount of overlap between each colony in core distribution (50% UD, out of a maximum of 0.5) and overall range (95% UD, out of a maximum of 0.95).
