Microplastic exposure and body condition in white-throated dipper (Cinclus cinclus) nestlings across anthropogenic landscapes in Scotland and Spain
Summary
Researchers quantified microplastic concentrations in fecal samples from white-throated dipper nestlings across gradients of human land use in Scotland and northern Spain. They examined relationships between land-use composition, microplastic exposure, and nestling body condition using mixed-effects models. The study provides evidence that these riverine birds are exposed to microplastics even at early life stages, with exposure levels varying across different landscape types.
In this study we quantified microplastic concentrations in faecal samples of white-throated dipper nestlings (Cinclus cinclus) sampled across gradients of anthropogenic land use in Scotland and northern Spain. We examined relationships between land-use composition, microplastic exposure and nestling body condition (SMI). Analyses were conducted using mixed-effects models to account for the hierarchical structure of the data (nestlings nested within nests, sites and catchments) and Principal Component Analysis (PCA) was used to summarise correlated land-use variables.

Microplastic exposure and body condition in white-throated dipper (Cinclus cinclus) nestlings across anthropogenic landscapes in Scotland and Spain
Researchers measured microplastic levels in fecal samples from white-throated dipper nestlings sampled across areas with varying degrees of human land use in Scotland and Spain. Using statistical models that accounted for the nested structure of the data, they examined how land-use patterns relate to both microplastic exposure and chick body condition. The findings contribute to understanding how anthropogenic landscapes influence microplastic exposure in freshwater-dependent bird species.
Microplastic exposure and body condition in White-throated dipper (Cinclus cinclus) nestlings across anthropogenic landscapes in Scotland and the Basque Country (Spain)
Researchers collected fecal samples from White-throated dipper nestlings across Scotland and Spain and found microplastics, mostly fibers, in 62.5% of broods, with concentrations linked to surrounding urban and agricultural land use. While no short-term effects on nestling body condition were observed, the findings highlight the widespread presence of microplastics in freshwater bird food chains across different landscapes.
Differences in microplastics in passerine feces across species, diet, and foraging location
Researchers analyzed fecal samples from five passerine bird species and found microplastics in all of them, with ground-foraging species carrying higher particle loads and insectivores ingesting more fragment-shaped particles than omnivores — suggesting that feeding behavior and habitat determine which bird species face the greatest microplastic exposure risk.
Microplastics characteristics and environmental correlates of their presence in the nests of white stork: An evidence for biotransfer and biocirculation in the ecosystem
Researchers surveyed microplastic characteristics across multiple urban water bodies, examining how land use, hydrology, and seasonal variation correlate with microplastic presence. Results showed that areas dominated by residential and commercial land use had consistently higher microplastic loads, with fibres the most prevalent particle type.
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.
