Seabird Plastic Ingestion and Welfare Impacts

Seabirds are among the most severely affected vertebrates by ocean plastic pollution, with ingestion causing internal injury, malnutrition, and death across dozens of species globally.

Key Facts

Over 90% of seabird species have been recorded ingesting plastic debris
Flesh-footed shearwaters on Lord Howe Island show some of the highest plastic loads of any bird
Plastic accumulates in chick stomachs when regurgitated by parents during feeding
Hard plastic causes intestinal blockages and perforation; leaching chemicals disrupt hormones
An estimated 1 million seabirds die from plastic ingestion or entanglement every year
Species like the Laysan albatross feed floating plastic to chicks, mistaking it for prey

Welfare Considerations

Plastic ingestion causes a slow, painful decline: birds feel satiated while starving, experience internal abrasion and chemical toxicity, and die over weeks or months. Chicks are especially vulnerable as they cannot regurgitate solid plastic as adults can. The welfare harm is diffuse, invisible, and affects entire breeding colonies.

What You Can Do

Reduce single-use plastic consumption to lower ocean pollution at source
Participate in or donate to beach and ocean plastic cleanups
Support research into seabird plastic toxicology and welfare assessment
Back policies that mandate producer responsibility for plastic packaging
Choose products with minimal or recyclable packaging to reduce plastic leakage
