Identification of microplastics in the digestive tract of Great Egret (Egretta alba) in Percut Sei Tuan, North Sumatra

Researchers examined the digestive tracts of great egrets in Percut Sei Tuan, North Sumatra, and found 15 microplastic particles in their stomachs and 13 in their intestines, with fibers being the most common type. The study suggests that these waterbirds are accumulating microplastics from their aquatic feeding habitats, reflecting significant plastic pollution in the local environment.

Microplastic contamination in waterbirds and their habitats: evidence from little egrets (Egretta garzetta) in tropical rice fields

Researchers investigated microplastic contamination in little egrets and their rice field habitats in tropical southern China. They found microplastics in water, sediment, feathers, and fecal samples, with fiber-shaped particles being the most common type. The study suggests that waterbirds can serve as useful indicators of microplastic pollution levels in agricultural wetland environments.

Assessment of microplastics in gastrointestinal tract of cattle egret (Bubulcus ibis) from a metropolitan city Lahore, Pakistan

Researchers examined the gastrointestinal tracts of cattle egrets from Lahore, Pakistan, and found significant levels of microplastics, with sheets and fibers being the most abundant types. Chemical analysis identified polyvinyl alcohol, polyisobutylene, and polyaramid as the main polymer compounds present. The findings indicate that even semi-aquatic bird species in urban environments are accumulating concerning levels of microplastic contamination.

Species-specific accumulation of microplastics in different bird species from South China: A comprehensive analysis

Across 24 bird species in South China, insectivorous birds accumulated significantly more small microplastics (under 0.1 mm) than other feeding guilds, while piscivorous birds accumulated more large microplastics (over 1 mm). Diet source was a stronger predictor of microplastic contamination than trophic level or body weight, with polypropylene and PET as the dominant polymer types found.

Microplastic accumulation in the gastrointestinal tracts in birds of prey in central Florida, USA

Microplastics were found in the gastrointestinal tracts of all 63 birds of prey examined from eight species in central Florida, with an average of nearly 12 plastic pieces per bird and microfibers making up 86% of the total. Processed cellulose was the most common material identified, followed by PET and a polyamide blend.

Abundance and characterization of microplastic pollution in the wildlife reserve, Ramsar site, recreational areas, and national park in northern Jakarta and Kepulauan Seribu, Indonesia

This is the first study to measure microplastic pollution in sediments across protected areas near Jakarta, Indonesia, including a wildlife reserve, a Ramsar wetland site, and a marine national park. Microplastics were found at all locations, with higher concentrations closer to human activity and during the dry season. The results suggest that even designated conservation areas are not spared from microplastic contamination.

Microplastic accumulation in the gastrointestinal tracts of nestling and adult migratory birds

Researchers examined microplastic accumulation in the gastrointestinal tracts of both nestling and adult migratory birds across six species, finding widespread plastic ingestion with fibers predominating, suggesting that microplastic exposure begins early in avian life stages.

Urban waterbirds shifting microplastics

Researchers found microplastics in the feces of two urban waterbird species in Kerala, India, with polyethylene, polypropylene, and polystyrene being the most common types. Both juvenile and adult birds were affected equally, suggesting that waterbirds can transport microplastics through ecosystems and serve as indicators of local plastic waste levels in freshwater environments.

Identification of the composition and abundance of microplastics in the digestive tract of fish in the Banjaran River, Banyumas District

Researchers identified and quantified microplastic composition and abundance in digestive tract contents of wild-caught fish from a coastal fishery, documenting ingestion rates, polymer types, and particle morphologies across multiple commercially important species.

Prey choice and ingestion of microplastics by common shelducks and common eiders in the Wadden Sea World Heritage Site

Researchers found microplastic contamination in over 92% of stomach samples and 74–86% of fecal samples from common eiders and common shelducks in the Wadden Sea, with plastic filaments under 5mm dominating, suggesting widespread and near-universal ingestion by these coastal seabirds.

Availability and assessment of microplastic ingestion by marsh birds in Mississippi Gulf Coast tidal marshes

Microplastics were found in the gastrointestinal tracts of marsh birds from tidal marshes along the Mississippi Gulf Coast, with ingestion rates and particle types reflecting both direct feeding on contaminated prey and incidental consumption from the environment.

Micro- and mesoplastic contaminants in marine diving ducks: A first assessments from the coast of Japan

Researchers conducted the first assessment of plastic contamination in two species of mollusk-eating seaducks wintering along Japan's Pacific coast and found microplastics in all ten birds examined. The vast majority of particles were tiny fragments under 200 micrometers, a size class previously overlooked in seaduck studies, suggesting these birds ingest microplastics primarily through their contaminated prey.

Ingestion of Plastics in a Wild Population of the Pacific Fat Sleeper (Dormitator latifrons)

This study documented plastic ingestion in the neotropical Pacific fat sleeper fish from an Ecuadorian wetland for the first time, finding plastics in 50% of individuals with an average of 30 particles per fish. Microplastics dominated the ingested plastic load, showing that wetland fish in South America are exposed to plastic pollution.

High microplastic pollution in birds of urban waterbodies revealed by non-invasively collected faecal samples

Researchers analyzed bird droppings from urban freshwater habitats in Germany and found microplastic particles, mainly fibers, in 98% of samples across all species studied. The pollution levels were substantially higher than those reported in other freshwater bird studies, likely reflecting the heavy contamination of urban waterways. Since all the investigated species are at least partially migratory, the findings suggest birds may transport microplastics over long distances.
