Common Scoter: Coastal Welfare Science

Key Welfare Facts

Common scoters winter in large rafts at sea, diving for bivalve molluscs on sandy seabed feeding grounds.
Oil spill events cause mass mortality through feather contamination and ingestion, representing severe welfare emergencies.
Disturbance by vessels causes diving and flight responses that significantly increase energy expenditure in winter.
UK breeding population in Scotland and Ireland is tiny and highly vulnerable to habitat disturbance.
Offshore wind farm development in feeding areas creates potential collision and displacement welfare risks.
Marine Special Protection Areas protect key wintering raft sites from disturbance and marine development.
Lead shot ingestion from shotgun pellets in feeding areas is documented as a mortality cause in some populations.

Welfare Assessment

Common scoter welfare is threatened by oil pollution, vessel disturbance, and potential offshore development impacts. Supporting Marine Protected Area designation for key wintering sites and oil spill response preparedness are the most effective welfare actions.

What You Can Do

Support Marine Special Protection Area designation for key common scoter wintering sites
Donate to oil spill response organisations providing wildlife rehabilitation for affected seabirds
Advocate for careful Environmental Impact Assessment of offshore wind proposals in key feeding areas
Record common scoter flocks for national sea duck monitoring surveys
