Purple sandpipers are specialised winter waders on rocky shores that face welfare challenges from storm events, food availability, and human disturbance.
Purple sandpipers depend on specific rocky intertidal habitats rich in the invertebrates they specialise in eating. Disturbance from photographers and beach visitors causes energy-wasting flight from feeding sites. Storm surge events temporarily displace birds from their territories. Chronic disturbance on popular beaches reduces feeding time and net energy balance during the critical winter period. Welfare-aware birdwatchers maintain distances that allow continued feeding without flushing. Shore protection through responsible use guidelines directly benefits individual bird welfare.
