Common sandpipers are summer visitors to upland rivers and streams, with welfare linked to invertebrate food supply and nest site availability.
Common sandpiper welfare during the breeding season depends on river and streamside quality providing invertebrate food for chick rearing. Upland rivers degraded by agricultural run-off or acidification support fewer invertebrates and therefore fewer breeding sandpipers with poorer chick welfare. Nest flooding from unseasonal rainfall is a natural welfare challenge that can be amplified by river management changes.
