Averaged regression results for relative use of mud flats by herring gulls compared with Amrum, sex_female, and daytime. Final generalized linear mixed models applied to 14 datasets with different starting values M = 1,.., 14 for data thinning. For example, herring gulls breeding on Amrum foraged on the tidal flats five times more frequently than herring gulls from Langeness (=0.2 odds ratio)
