  1. Model set 1 concerns the analysis of individual flights, model set 2 concerns the analysis of movement metrics per duck day in the Netherlands, and model set 3 concerns the analysis across Western Europe. Only the top three and null models are shown (full details in Additional file 1: Table S2). Best fitting models without uninformative parameters [49] are in bold. TOD is time of day (sunrise, day, sunset or night), and PC1 and PC2 are principal components of weather parameters, mainly corresponding to temperature and wind/precipitation, respectively. Flight distance and home range parameters were log-transformed
