The common sandpiper breeds along fast-flowing upland rivers and streams in Scotland and northern England, and its welfare is linked to clean water quality and riverbank habitat.
Livestock poaching of riverbanks destroys nesting habitat and increases sedimentation, smothering the gravel invertebrate communities sandpipers depend on. Agricultural runoff reducing water quality and invertebrate diversity affects food availability. Mink predation at nest sites causes direct welfare and population impacts. Their migration exposes birds to hunting pressure in some Mediterranean countries.
