Plastic pollution devastates our ocean, and its impact on marine wildlife—especially seabirds—is severe and far-reaching. Seabirds breed on land but search for food at sea, bringing them into frequent contact with plastic pollution accumulating both along shores and in surface waters worldwide. Unfortunately, ingesting plastics can prove to be deadly for these amazing animals.

Eating plastics for seabirds can obstruct their digestive systems, preventing them from eating actual food, and leading to starvation. Sometimes it takes only one piece of plastic to block the passage of food. Plastic ingestion has been found in every family of seabird. Below are details on how some species are uniquely impacted by plastic pollution.
- Northern fulmar: Northern fulmars are surface feeders, diving into the ocean to snag prey. Unfortunately, their foraging habits bring them face to face with floating plastic fragments which they mistake for food. A 2015 study in the Arctic revealed a staggering 90% of northern fulmars studied had plastics in their stomachs. These creatures are so prone to eating plastics that both the Canadian government and OSPAR Commission (the mechanism through which the European Union and 15 other governments cooperate to protect the North East Atlantic marine environment) use this species in their monitoring programs to track long-term trends in ocean plastic pollution.

- Short-tailed shearwater: Short-tailed shearwaters are also particularly vulnerable to plastic pollution, frequently consuming both rubber—such as balloons—and hard fragments. A 2014 study in Tasmania found plastic in the stomachs of 96% of short-tailed shearwater chicks studied.
- Laysan albatross: The Laysan albatross skims the ocean surface with its beak to hunt for prey. This hunting behavior makes it likely that the albatross will accidentally consume plastic debris like consumer products (e.g., hard fragments, lighters, buttons) or fishing lines. Adult albatrosses also feed their chicks by regurgitating food, unknowingly passing plastics on to their young. A heartbreaking 1997 study on Midway Atoll, a remote Pacific island, found 97.5% of Laysan albatross chicks had plastic in their stomachs.

- Petrel: More than 50% of petrel species are listed as “threatened” or “near threatened” by the International Union for Conservation of Nature (IUCN). Petrels often inhabit areas with high concentrations of plastic pollution such as the high seas and mid-ocean gyres. Unlike other seabirds, they struggle to regurgitate plastic. This means the plastics they ingest tend to remain in their bodies for extended periods.

What can you do?
If we fail to take action, studies predict that 99% of seabird species will ingest plastic by 2050, which is devasting given how vulnerable seabirds are to even the smallest amount of plastic. Ocean Conservancy is committed to protecting our ocean, wildlife and communities from plastic pollution. But we can’t do it alone. Here is how you can join the fight:
- Reduce plastic use: To tackle our plastic pollution crisis, we need to use less plastic. We can each do our part by avoiding single-use plastics where possible in our daily lives from carrying a reusable water bottle and bag to skipping a straw. These small actions add up and collectively reduce the amount of plastic waste we create, while sending a clear signal to plastic producers that we are fed up with single-use plastics.
- Clean up plastic pollution before it enters the ocean: Cleaning up plastic waste, whether on the beach, along a river, or in your neighborhood park, helps eliminate the likelihood that it will later be consumed by seabirds or other marine life. One of the best ways to do this is by joining the International Coastal Cleanup® (ICC). Use our map to find a coordinator planning a cleanup in your region. Want something closer to home? Team up with friends and family to clean up your favorite beach or beloved park. If you see plastic on beaches, shores or elsewhere, remember to clean it up—it could save a seabird’s life.
- Push for policy change: Advocate for legislation to address plastic pollution by holding corporations accountable for the waste they create, expanding support for reuse and refill systems and much more. Visit Ocean Conservancy’s Action Center to see how you can get involved.
