Description
Summary:Occupancy surveys in November 2008 (Southwell and Emmerson 2013) found a total of 31 Adelie penguin breeding sites off the Vestfold Hills. The boundaries of breeding sub-colonies at 26 of these sites were subsequently mapped from vertical aerial photographs taken for abundance surveys on 18-21 November 2009 (for details of aerial photography see Southwell et al. 2013). These boundaries were mapped with a buffer distance of approximately 1-3 m from the perimeter of penguin sub-colonies.
