The oystercatcher, with its striking black and white plumage and orange bill, is one of the most recognisable shorebirds. Despite its abundance, specific welfare challenges arise from human disturbance of nesting beaches and competition with shellfish harvesting.
Oystercatcher welfare at beach nesting sites is directly affected by dog disturbance and human beach recreation. Nests on accessible beaches are frequently destroyed by dogs and quadbikes. Adults disturbed from nests in warm weather leave eggs to overheat — ambient beach temperatures in summer can exceed lethal egg temperatures within 15 minutes of parent departure. Shellfish harvesting regulations that reduce cockle and mussel availability at key wintering sites force birds to travel further and may cause nutritional stress. Oystercatchers that persist at good feeding sites show high site fidelity and good welfare outcomes — disturbance is the primary management concern.
