Individual spatial consistency and dietary flexibility in the migratory behaviour of northern gannets wintering in the northeast Atlantic (dataset)

This datafile contains the biometric data used by Grecian, Williams et al. to examine the migratory behaviour of northern gannets breeding at four colonies in the northeast Atlantic. Each row represents a sample from an individual and contains data on; colony of origin, year of sampling, animal ID, sex, tarsus length (mm), wing length (mm), bill length (mm), mass (g), and scaled mass estimated following Peig & Green. For those animals that were tracking with geolocators the data frame also contains the December mean latitude and longitude. For those animals that were sampled for stable isotope analysis the data frame also contains primary feather d13C and d15N values, and isotopic cluster assignment.

本数据集收录了Grecian、Williams等人用于探究北大西洋东北部4个繁殖群落的北方塘鹅迁徙行为的生物测定数据。每一行对应一个个体样本，包含如下信息：个体所属繁殖群落、采样年份、动物编号、性别、跗跖长度（mm）、翼长（mm）、喙长（mm）、体重（g），以及遵循Peig与Green的方法估算的标准化体重。对于使用地理定位器（geolocators）进行追踪的个体，数据框中还包含12月平均纬度与经度数据；对于接受稳定同位素分析的个体，数据框中还收录了初级飞羽的δ13C、δ15N值，以及同位素聚类分组结果。
