Plastic pollution in a special protected area for migratory birds
AI summary Read the abstract
This study measured plastic pollution — including microplastics — in a special protected area designated for migratory birds, finding widespread contamination despite the area's protected status. The presence of plastics poses ingestion and entanglement risks to bird species that rely on the habitat.
Plastic pollution in Special Protected Areas for Migratory Birds and Sites of Community Importance is a growing environmental concern. These areas, often designated to provide safe habitats for migratory bird species, are increasingly threatened by plastic litter. In this study, we conducted the first assessment of plastic litter, ranging from macro to microplastics, in beach sediments from two sites (Montorsoli Beach and Pylon Beach) along the coast of the Strait of Messina, a Special Protected Area, to assess beach quality and ecological risk. The selected beaches for this study are representative example of two different possible source of anthropogenic contaminations. Plastic density ranged from 1.2 pieces/m2 to 0.1 pieces/m2, Montorsoli and Pylon Beach, respectively. The most abundant plastic litter consisted of plastic pieces ranging in size from 0.5 cm to 50 cm. Several anthropogenic microparticles were identified, including Polypropylene, Polyethylene, Polyethylene terephthalate, Polytetrafluoroethylene, cotton fibers and cellulose-based materials. Montorsoli beach had a high percentage (91 %) of Polymethyl methacrylate (PMMA). While in Pylon beach the main polymer was cotton (49 %). Furthermore, calculated pollution indices showed that Montorsoli was very dirty compared to Pylon beach. Furthermore, the presence of PMMA pellets found at Montorsoli beach may endanger marine birds that depend on the resources of these areas, which are designated as Special Protection Areas for rare and vulnerable bird species. This baseline assessment not only provides crucial information on the current status of plastic pollution, but also offers valuable data that can be instrumental in effective regional management efforts.

Microplastic invasion of coastal protected areas imperceptibly threatens avian reproduction
AI summary Read the abstract
This study found that tiny plastic particles (microplastics) are invading protected coastal areas where seabirds nest and reproduce. The microplastics are harming birds' ability to successfully breed and raise their young. This matters because it shows how plastic pollution is damaging wildlife even in areas we've set aside for protection, and birds often serve as early warning signs for environmental threats that could eventually affect human health too.
Birds and plastic pollution: recent advances
AI summary Read the abstract
This review summarizes how plastic pollution affects birds across both aquatic and terrestrial habitats, covering ingestion, entanglement, and chemical exposure from macro- and microplastics. Researchers found that hundreds of bird species have accumulated plastic in their tissues, with effects ranging from physical injury to hormonal disruption and reproductive harm. The study positions birds as valuable indicator species for monitoring the broader environmental impact of plastic pollution.

Beaches within bird protection areas in the Bay of Biscay contained 145-382 microplastic particles per kg of dry sand, relatively high for European beaches, with open coastline beaches showing higher densities than sheltered estuarine ones, and bird droppings from shags and gulls confirming fiber ingestion.
Microplastic accumulation in various bird species in Turkey
AI summary Read the abstract
Researchers analyzed microplastic contamination in 12 bird species in Turkey, providing the first data of its kind for the country. They found microplastics in all species examined, with variations in particle types and concentrations across different birds. The study contributes to the growing evidence that microplastic pollution affects wildlife across diverse habitats and feeding strategies.

AI summary Read the abstract
Researchers found microplastics in surface water, sediment, and the droppings of migratory birds at a Chinese wetland lake, raising concerns about how birds can transport microplastics across long distances. The study suggests that migratory birds may be spreading plastic contamination between distant habitats.
