Fecal samples from migratory birds were collected from contaminated wetlands in the Bunker Hill Lower Basin Coeur ’d Alene River Watershed and from a Hepton Lake reference area St. Joe River Watershed during 2022-2024. Mitochondrial CO1 metabarcoding was used to confirm bird taxa from which samples were collected. CO1 primers with Illumina adaptors: CO1-F TCGTCGGCAGCGTCAGATGTGTATAAGAGACAGAACATTCAGCCATCTTACCCGTG CO1-R GTCTCGTGGGCTCGGAGATGTGTATAAGAGACAGACAGGGAGTGATAGRAGKAGTAGG Also, chloroplast rbcL metabarcoding was used to identify plant taxa recently consumed by the birds, which can be found at DOI: 10.23719/1532393
