Purple sandpipers are hardy Arctic breeders that winter on rocky shores around the UK, with welfare challenges from habitat disturbance, pollution events, and declining food availability.
Purple sandpiper welfare is challenged by disturbance on wintering rocky shores. Dog walking and human recreation on shoreline rocky outcrops causes repeated disturbance that forces birds to fly when they would otherwise be feeding. Given the cold conditions and high energy demands of winter survival, repeated interruption of feeding periods causes energetic stress that can affect survival. Oil pollution events on rocky shores can contaminate the invertebrate food supply and directly oil birds, causing hypothermia from feather waterproofing damage. Recreational climbing on sea rocks during winter months causes disturbance that is locally significant for small wintering groups.
