Green sandpipers are solitary waders that use UK waterside habitats as wintering and passage sites, with welfare tied to clean shallow water margins.
Green sandpiper welfare at UK sites depends on clean, shallow water margins with abundant invertebrates. Water pollution reducing invertebrate diversity depletes food supply at individual territories. Their secretive nature makes them vulnerable to being flushed repeatedly by dogs and walkers before detection. Each disturbance event wastes energy and reduces net foraging success during the day. Waterside habitat management maintaining natural margins with muddy shallow areas and protective vegetation directly supports green sandpiper welfare at wintering and passage sites.
