The common sandpiper is a summer migrant that bobs along rocky stream banks and loch shores from April to August. Its welfare depends on clean, invertebrate-rich upland rivers and freedom from disturbance at nest sites.
Common sandpiper welfare at breeding sites is affected by river disturbance from kayaking, wild swimming and dog exercise. Nests in bankside vegetation are easily found by dogs and foxes — disturbance that flushes incubating birds increases nest predation risk. Water quality affects the aquatic invertebrate communities that common sandpipers depend on. Rivers affected by agricultural run-off show lower sandpiper densities and breeding success. The species is relatively tolerant of human presence when nest sites are undisturbed — breeding pairs at accessible rivers become habituated to walkers maintaining appropriate distance. Upland river management that maintains bankside vegetation and reduces nutrient pollution directly supports common sandpiper welfare.
