We included the distance to nearest foraging site (forage), presence of Grey Plover (gp)/Great Knot (gk)/Common Greenshank (cg), water depth (depth), distance to nearest road (road), abundance of all species combined (abund), bird species richness (spp) and vegetation cover (veg) as the fixed effects of the GLMMs. LL represents the log-likelihood. K is the number of parameters in the model. ∆AICc is the absolute difference in the Akaike’s Information Criterion value adjusted for small sample sizes (AICc) between the best fit model and the model under consideration [the model with ∆AICc value 0 has the most support, values between 0 and 2 have substantial support, and values greater than 2 have less support (Burnham and Anderson 1998)]. w_i is the Akaike weight which provides a measure of relative support for each model
