Investigation of Microplastic in Pellets from the Selected Piscivorous Bird Along the Wetlands of Coimbatore City in Tamil Nadu State of India
AI summary Read the abstract
Researchers examined regurgitated pellets from Common Kingfishers along Indian wetlands and detected polyethylene and polypropylene microplastic fibers in 26% of pellets, providing the first evidence of microplastic ingestion by this piscivorous bird species in southern India and highlighting contamination within freshwater food webs.
The presence of microplastic has reported in the pellets of various water birds across the world but little information were available on plastic ingestion of fresh water birds in India.The Common Kingfisher (Alcedo atthis) pellets were collected along the wetlands of Noyyal River.In total, 50 regurgitated pellets were examined between September, 2021 to March, 2022.The putative plastic elements were detected from visual examination followed by -FTIR and SEM-EDS.There are two types of polymers namely polyethylene fibers and polypropylene fibers were detected from 13 regurgitated pellets.This was the first reconnaissance study examined the presence of micro plastic fragments in regurgitated pellets of the Common Kingfisher in the Southern India (Fig. 1).This is an important document to understand the impact of microplastic pollution in food web of fresh water ecosystem.

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.
Urban waterbirds shifting microplastics
AI summary Read the abstract
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.
Assessment and quantification of microplastic contamination in fishes with different food habits from Beel wetlands
AI summary Read the abstract
Researchers examined microplastic contamination in fish from freshwater wetlands in India, finding particles in the digestive tracts of all 90 fish sampled across different feeding types. Carnivorous fish accumulated the most microplastics, followed by omnivores and then herbivores, suggesting trophic transfer plays a role. The most common particles were fibers in the 100 to 500 micrometer size range, with polyethylene and nylon as the dominant polymer types.
Species-specific accumulation of microplastics in different bird species from South China: A comprehensive analysis
AI summary Read the abstract
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.
