Common sandpiper ecology along upland rivers requires clean, invertebrate-rich streams with exposed gravel banks for nesting and foraging.
Sandpiper welfare is tightly coupled to invertebrate abundance in their riverside territory. Rivers with poor water quality or reduced flow have fewer invertebrates, requiring adults to forage further and work harder to provision chicks. Improving river water quality and maintaining riparian vegetation directly improves individual sandpiper welfare by increasing prey availability in breeding territories. Each invertebrate-rich river system supports sandpiper welfare across the breeding season.
