Justification of Red List category

Although this species has a comparatively small breeding range size for a shorebird (extent of occurrence c. 950,000 km²), this still far exceeds Criteria B thresholds. It also has a large estimated population size (3,500,000 mature individuals; Partners in Flight 2023), and so does not approach Criteria C or D thresholds. The population trend is suspected to be declining, but not at a rate that meets or approaches thresholds under Criterion A. Western Sandpiper is therefore listed as Least Concern.

Population size: 3500000 mature individuals

Population trend: decreasing
