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.
