Marine Debris Impacts on Seabirds

Marine plastic and other debris causes significant welfare harm to seabirds through ingestion, entanglement, and nest incorporation. Understanding these impacts informs conservation priorities.

Key Facts

Over 90% of seabirds have ingested plastic debris according to some studies
Albatrosses and petrels are particularly affected, feeding plastic to chicks as food
Entanglement in fishing line and nets causes drowning, injury, and starvation in seabirds
Monofilament fishing line incorporated into nests can entangle and kill chicks
Plastic accumulation in seabird digestive systems causes a false sense of satiety, reducing actual food intake

Welfare Considerations

Marine debris welfare impacts on seabirds are severe and largely invisible to human observers. Chicks fed plastic fragments by parents experience a false sense of fullness and fail to receive adequate nutrition, causing growth failure and starvation. Plastic in adult digestive systems reduces stomach capacity and may cause toxic effects from leaching chemicals. Entanglement in fishing gear causes traumatic injury and drowning. The welfare harm extends from individual birds to population-level impacts as breeding success is reduced. Reducing plastic waste at source is the only long-term solution.

What You Can Do

Reduce single-use plastic consumption to decrease marine plastic pollution
Participate in beach and shoreline litter picks to remove debris before it enters the marine environment
Support fishing line recycling programs to prevent monofilament from reaching seabird colonies
Donate to organizations monitoring and removing marine debris from seabird breeding sites
