This dataset contains: 1) count data from a series of surveys of brown skua nest numbers and breeding success conducted from 2008/09 to 2017/18; 2) historic skua nest count data and concurrent estimates of rabbit abundance (1974/75 to 2009/10); 3) stable isotope data from feather samples taken from skua chicks during the 2017/18 season to compare stable isotope ratios between different feather types; 4) stable isotope data from feather samples taken from skua chicks from 2008/09 to 2017/18; 5) a small dataset of stable isotope data from skua prey tissue samples; 6) the nest locations of skuas surveyed in the seasons 2009/10, 2012/13 and 2017/18. This data was used to assess the effect of rabbit eradication (completed in 2011) on brown skua breeding and diet.
