The Welfare of Oiled Wildlife During Spills

Oil spills cause acute and prolonged suffering in seabirds, marine mammals, and other wildlife.

Key Facts

The Deepwater Horizon spill affected an estimated 8,000 sea turtles and 82,000 birds
Oil destroys the insulating properties of bird feathers and mammal fur — causing hypothermia
Oil ingestion causes internal organ damage, anemia, and immune suppression
Rehabilitation of oiled wildlife is resource-intensive but effective for some species

Welfare Considerations

Oil spills cause some of the most visible and acute wildlife welfare emergencies. Birds coated in oil cannot fly or thermoregulate — they sink in freezing water or die from hypothermia on shore. Marine mammals lose fur insulation and ingest oil while grooming. Death from exposure, starvation, or organ damage can take days. Rehabilitation centers treat oiled wildlife but face enormous scale challenges in major spills. Prevention — through improved drilling safety, pipeline integrity, and tanker regulations — is the most effective welfare intervention, but rapid response systems save thousands of animals when spills occur.

What You Can Do

Support organizations maintaining oiled wildlife response capacity
Advocate for stronger oil spill prevention regulations and enforcement
Support drilling moratoriums in ecologically sensitive marine areas
Donate to oil spill response funds when major incidents occur
