ClearPrevalência e tipos de plásticos em Albatrozes e Petréis (aves: procellariiformes)
Researchers quantified and classified plastic debris in Procellariiformes seabirds — albatrosses and petrels — found on Brazilian beaches, finding plastic ingestion in multiple species. These ocean-going birds are among the most vulnerable to plastic pollution because they feed from the ocean surface where plastics concentrate.
Métodos para avaliação da exposição a poluentes plásticos em procellariiformes
This paper reviews methods for assessing plastic exposure in Procellariiformes seabirds — including albatrosses and petrels — focusing on how to measure plastic ingestion in both live and beached birds. Standardized methods are needed to monitor how plastic pollution affects these ocean-going birds over time.
Plastic ingestion by seabirds in New Caledonia, South Pacific
Researchers examined stomach contents of 90 seabirds from 12 species in New Caledonia and found plastic debris in 14.4% of individuals, with the highest rates in procellariids (petrels and shearwaters), providing the first plastic ingestion baseline for this Pacific island region.
Plastic ingestion in seabirds of the western Indian Ocean
Researchers examined stomach contents of 222 seabirds from nine species in the western Indian Ocean and found plastic in all species, with tropical shearwaters (79%) and Barau's petrels (59%) most affected, and juvenile birds carrying significantly greater plastic mass than adults, indicating regional ocean plastic pollution and age-dependent exposure risks.
Microplastic ingestion: Are seabirds more affected than other marine species?
This review examines whether seabirds ingest plastic more frequently than other marine species, finding they are among the most affected groups with high rates of plastic ingestion documented across species. The review discusses factors including foraging behavior, habitat, and ocean plastic concentrations that explain why seabirds are particularly vulnerable.
Exposure to microplastics by pelagic and coastal seabirds from temperate and tropical environments
Researchers examined microplastic exposure in pelagic and coastal seabird species from temperate and tropical marine environments, using the birds' broad spatial distribution and feeding behavior to assess microplastic distribution and concentration patterns across oceanic regions.
The hidden cost of following currents: Microplastic ingestion in a planktivorous seabird
Researchers documented microplastic ingestion in Mediterranean storm petrels, finding that these planktivorous seabirds ingest microplastics while foraging in pelagic areas where plastic debris accumulates alongside their planktonic prey in ocean currents.
Assessing the risks of marine debris ingestion to Procellariiform seabirds
This study assessed the risks of marine debris ingestion for Procellariiform seabirds — one of the world's most threatened bird groups — finding that plastic ingestion poses significant risks to health and survival. The analysis highlights how plastic pollution interacts with other stressors affecting globally threatened seabird species.
Characterisation of plastic debris (macro-, meso-, and microplastics) from stranded alcids in southern Spain
Researchers analyzed plastic debris in the digestive tracts of 123 Atlantic puffins and razorbills collected along the Andalusia coast in Spain between 2022 and 2024. Puffins had significantly higher plastic prevalence (65%) than razorbills (18.4%), with fibers being the most common type in both species, suggesting different foraging behaviors drive differential exposure.
First assessment of debris pollution in the gastrointestinal content of juvenile Magellanic penguins (Spheniscus magellanicus) stranded on the west south Atlantic coasts.
This study found anthropogenic debris including plastics and fibers in 100% of juvenile Magellanic penguins stranded on the Argentine coast, with microparticles making up the vast majority. This is the first assessment of debris ingestion in juvenile Magellanic penguins and raises concerns about the impact of plastic pollution on these vulnerable young seabirds.
Marine debris ingestion by adults and fledglings of Swinhoe's storm petrels in the Republic of Korea
Researchers analyzed stomach contents of stranded Swinhoe's storm petrel carcasses from a Korean breeding colony and found that both adults and fledglings ingested predominantly microplastics, with juveniles consuming more plastic by weight than adults and the two age groups ingesting different particle shapes, suggesting separate foraging behaviors.
Plastic debris ingestion by seabirds on the Korean Peninsula
Researchers examined plastic ingestion in 387 seabirds of 11 species on the Korean Peninsula and found the highest frequency in Swinhoe's storm petrels (93.7%), with plastic characteristics varying by species feeding ecology, providing baseline data for monitoring marine debris impacts in East Asian waters.
Size and dynamics of microplastic in gastrointestinal tracts of Northern Fulmars ( Fulmarus glacialis ) and Sooty Shearwaters ( Ardenna grisea )
Researchers examined microplastic in the gastrointestinal tracts of 143 Northern Fulmars and 25 Sooty Shearwaters stranded on Oregon and Washington beaches, finding plastic in 89.5% and 64% of birds respectively, with larger particles concentrated in the stomach's upper chamber and no significant reduction in plastic load in birds held in a plastic-free rehabilitation environment for up to seven days.
Microplastics in Seabird Feces from Coastal Areas of Central Chile
Researchers analyzed fecal samples from Dominican gulls, Magellanic penguins, and Humboldt penguins in coastal Chile for microplastic content, finding microplastics in all three species. The results document microplastic ingestion by multiple seabird species in Chilean coastal ecosystems, reflecting ocean contamination in the southeastern Pacific.
Long-term variations in size and polymer type of meso- and microplastics in seabirds and on beaches since the 1980s
Researchers analyzed plastics found in seabird stomachs and on beaches at a remote South Atlantic island across several decades since the 1980s to track long-term changes in marine plastic pollution. They found shifts in the types and sizes of plastic polymers over time, reflecting changes in global plastic production and how plastics degrade at sea. The study demonstrates that seabirds can serve as effective long-term monitors of floating plastic pollution trends in the ocean.
Seabird plastic ingestion differs among collection methods: Examples from the short-tailed shearwater.
This study compared plastic loads in short-tailed shearwaters collected as fishing bycatch versus naturally dead beached birds, finding that naturally dead birds carried significantly more plastic debris. The results suggest that studies relying only on beached carcasses overestimate typical plastic ingestion rates in seabird populations.
Floating macro- and microplastics around the Southern Ocean: Results from the Antarctic Circumnavigation Expedition
Researchers surveyed floating macro- and microplastic pollution around the Southern Ocean islands, providing baseline abundance estimates for high southern latitudes. The data reveal that plastic contamination extends even to remote polar regions, with seabirds in the area confirmed to have been ingesting plastics since at least the 1960s.
Seabirds from the poles: microplastics pollution sentinels
Researchers reviewed four decades of studies on microplastic ingestion by seabirds in Arctic and Antarctic regions, covering at least 13 species. They found that polar seabirds regularly ingest microplastics, with polyethylene being the most common type detected. The study highlights that even some of the most remote ecosystems on Earth are not immune to plastic pollution.
Pellets and Prey Remains as Indicators of the Diet of Two Sympatric Skuas (aves: Stercorariidae) on King George Island, Antarctica
Researchers analyzed pellets and prey remains from two species of Antarctic skuas to understand their feeding habits. This type of dietary study in polar seabirds can reveal whether marine predators are inadvertently ingesting microplastics along with their prey.
Characterization of Plastics Ingested by the Bioindicator Cory’s Shearwater from Tenerife Island (Canary Islands): Implications for Marine Environmental Monitoring
Researchers characterised 674 plastic items found in the stomachs of Cory's shearwater fledglings from the Canary Islands, finding that ingested plastics were predominantly large microplastics (1-5 mm, 82%) with threadlike morphology, and that the birds serve as effective bioindicators of marine plastic pollution in the eastern Atlantic.
Ingestion of plastic debris by commercially important marine fish in southeast-south Brazil
Scientists visually examined 965 specimens of eight commercially exploited fish species off the southeast-south coast of Brazil for plastic debris ingestion, finding plastic in multiple species across different marine habitats.
Charismatic Species as Indicators of Plastic Pollution in the Río de la Plata Estuarine Area, SW Atlantic
Researchers examined sea turtles, marine mammals, and seabirds in the Río de la Plata estuary as indicator species for plastic pollution, finding evidence of plastic ingestion and entanglement across all three groups. These charismatic species can serve as early warning systems for the extent of marine plastic pollution in South Atlantic coastal areas. Monitoring plastic exposure in these animals provides data relevant to understanding plastic loads in waters also used for fishing and recreation.
Threat of plastic pollution to seabirds is global, pervasive, and increasing
Researchers performed a global spatial risk analysis combining ocean plastic distribution data with the ranges of 186 seabird species to assess which birds face the greatest threat from plastic ingestion. They found that nearly 60% of all seabird species have been documented with plastic in their guts, and predicted that 99% of species will be affected by 2050 at current trends. The study identifies the Southern Ocean as a particular hotspot of risk where high plastic concentrations overlap with diverse and vulnerable seabird populations.
Contamination of coastal and marine bird species with plastics: Global analysis and synthesis
This review summarizes global data on plastic contamination in coastal and marine bird species across all seven continents, finding that seabirds like fulmars, shearwaters, and albatrosses are the most heavily affected. Birds ingest microplastics, mesoplastics, and macroplastics that can cause death directly through gut blockage and indirectly through toxic chemicals absorbed onto or released from the plastic. Several contaminated species are already classified as endangered.
