Macquarie Island Brown Skua breeding and diet data

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.

本数据集包含以下六类数据：1) 2008/09至2017/18年度开展的一系列棕贼鸥（brown skua）巢数量与繁殖成功率调查计数数据；2) 1974/75至2009/10年度的历史贼鸥巢计数数据，以及同期兔类种群丰度估算值；3) 2017/18年度取自贼鸥雏鸟羽毛样本的稳定同位素数据，用于对比不同羽毛类型间的稳定同位素比值；4) 2008/09至2017/18年度取自贼鸥雏鸟羽毛样本的稳定同位素数据；5) 一组小型贼鸥猎物组织样本的稳定同位素数据集；6) 2009/10、2012/13及2017/18三个调查季的贼鸥巢位调查数据。
