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.
Microplastics in fishes as seabird preys in Jakarta Bay Area
Microplastics were detected in five fish species collected from Jakarta Bay, Indonesia, with fishes serving as prey for little-black cormorants, indicating that microplastic contamination enters seabird food webs through fish prey in Indonesian coastal waters.
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.
Investigation of Microplastic in Pellets from the Selected Piscivorous Bird Along the Wetlands of Coimbatore City in Tamil Nadu State of India

Ingestion of Unusual Items by Wetland Birds in Urban Landscapes
Researchers surveyed regurgitated pellets from colonial wetland birds in two Indian cities, finding that over half of pellets in Coimbatore contained rubber bands, rubber balloons, and small plastic debris, demonstrating widespread ingestion of anthropogenic litter by urban birds.
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.
