The purple sandpiper is a specialised wader of rocky shores and pier structures that winters in small numbers around British coasts, with each individual particularly significant given the species limited presence in the UK.
Purple sandpiper welfare at British wintering sites depends on the quality of rocky intertidal habitat with accessible invertebrate communities. Oil spills on rocky shores are the most acute welfare threat, coating feeding areas and prey organisms. Disturbance from recreational users of piers and jetties causes displacement during the limited daylight feeding window. Wave exposure at rocky sites means birds face significant physical welfare demands during storms.
