Consumo incidental de plástico y otros materiales antropogénicos por parte de Coragyps atratus (Bechstein, 1793) en un vertedero de basura de Ecuador
AI summary Read the abstract
Researchers found that 100% of regurgitated pellets from black vultures (Coragyps atratus) at an Ecuadorian landfill contained anthropogenic materials, with plastics being the most common item, demonstrating widespread incidental plastic ingestion by scavenging birds.
En este estudio se analiza y discute la ingesta de plástico y otros materiales antropogénicos por parte de Coragyps atratus en un vertedero de residuos suburbano de Calceta, Provincia de Manabí, Ecuador. De un total de 112 egagrópilas analizadas, el 100% contenía materiales antropogénicos siendo los más conspicuos, diferentes tipos de plásticos y microplásticos, además de metales, vidrio, suelo y otros. Se discute y contrasta con la bibliografía la importancia relativa de los materiales antropogénicos encontrados, así como su potencial impacto en la especie y para el ser humano.

First report on occurrence and characterization of microplastics in feces of Corvus splendens (Vieillot, 1817)
AI summary Read the abstract
Researchers found microplastics in 92% of fecal samples from Indian house crows (Corvus splendens), with polyester fibers dominating at 99% of particles and an average of 2.64 particles per sample. This first-ever report of microplastic ingestion in a terrestrial urban bird species highlights how plastic pollution has permeated even land-based wildlife food webs, far beyond marine and waterbird systems.
PLASTIC AND BLOOD: A FAKE FOOD FOR THE BLACK VULTURE (Coragyps atratus) IN THE URBAN ENVIRONMENT
AI summary Read the abstract
Researchers documented black vultures in an urban Brazilian environment consuming low-density polyethylene plastic bags contaminated with blood residue, suggesting the birds mistook the bags for animal viscera—raising concern about plastic ingestion in urban scavengers and its potential health consequences.
Presence of microplastics in raptor pellets
AI summary Read the abstract
Scientists found tiny plastic fibers in nearly all the pellets (regurgitated waste) collected from birds of prey in Chile, meaning these plastics are working their way into predator diets through the animals they eat. Since raptors sit near the top of the food chain, this suggests plastic pollution is spreading through entire ecosystems—a warning sign for the food chains that humans are also part of.
