Oil spills cause catastrophic welfare harm to seabirds, with oiled birds rescued, cleaned, and rehabilitated by specialist teams whose work provides direct individual welfare benefit.
Seabird oil spill welfare response provides direct individual welfare benefit to birds that would otherwise die slowly from hypothermia and organ failure. Oiled birds experience acute distress from the loss of feather function and the physiological effects of oil ingestion. Rehabilitation requires skilled handling to minimise stress while achieving thorough cleaning. Birds that survive rehabilitation and are successfully waterproofed can be released - but only when genuinely clean and able to regulate temperature. The welfare success rate of oil spill response varies by species and oil type. Preventing spills through robust tanker regulation and response infrastructure is the most effective welfare intervention.
