The common sandpiper is a summer visitor to upland rivers and lakes, arriving from West African wintering grounds to breed on shingle and grass banks. Individual breeding welfare depends on habitat quality, disturbance, and predation pressure.
Individual sandpiper welfare during breeding is primarily determined by freedom from disturbance at nest sites and access to sufficient aquatic invertebrate prey. Nests flushed repeatedly by approaching walkers and dogs fail through egg chilling and increased predation risk. The welfare cost of recreational disturbance falls on individual birds attempting to complete one of the most energetically demanding periods of their annual cycle. Staying on paths and keeping dogs under control near riverbanks during May-August significantly reduces disturbance.
