Microplastic (MP) pollution is ubiquitous throughout the planet and has become a global concern. There are many reports of microplastic ingestion by seabirds and inland waterbirds. However, only handful of studies have investigated the microplastic ingestion in the terrestrial birds. We are the frst to report evidence of microplastics in the feces of Indian house crows Corvus splendens. Microplastics were detected in 92% of the fecal samples. Mean number of microplastics obtained for each feces was 2.64±1.47 particles. Only two diferent shapes of microplastic were observed in our study—fbers (99%) and fragments (1%). Average length for microplastics was 1727.16 µm, and width was 27.07 µm. About 97% of the plastic particles were below 5 mm. Black was the prominent color of microplastics followed by blue and gray. FTIR–ATR revealed that polyester fbers were prominent (21.21%), followed by polypropylene (16.67%), LDPE (15.15%), HDPE (9.09%), cellulose acetate (7.58%), and nylon (6.06%). SEM revealed the degraded surface of microplastics and EDX revealed that carbon/oxygen ratio was 69:22 confrming that the microplastic was a polymer. Understanding the fate of microplastics in the terrestrial ecosystem is crucial, hence further broader works should be carried out to understand microplastics in the terrestrial ecosystem.
