An occupancy survey in January 2011 found a total of 14 islands/sites in Windmill group had populations of breeding Adelie penguins. The boundaries of breeding colonies at 11 of the 14 islands were subsequently mapped for abundance surveys. Four of the islands, Nelly Island, Hollin Island, Midgley Island and Beall Island were mapped from aerial photos taken in January 2011. Images were taken on the 2 January 2011 [Hollin, Midgley, Beall] and 23 January 2011[Nelly]. Mapping involved digitising polygons around sub-colonies from vertical aerial photographs. The boundaries were mapped with a buffer distance of approximately 1-3 m from the perimeter of penguin sub-colonies.
