Fecal samples from migratory birds were collected from Pb 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. Chloroplast rbcL metabarcoding was used to identify plant taxa recently consumed by the birds. rbcL primers with Illumina adaptors: RBCL-F TCGTCGGCAGCGTCAGATGTGTATAAGAGACAGYGATGGACTTACNAGTCTTGATCGTTACAAAGG RBCL-R GTCTCGTGGGCTCGGAGATGTGTATAAGAGACAGGNCCATAYTTRTTCAATTTATCTCTTTCAACTTGGATNCC Also, mitochondrial CO1 metabarcoding was used to confirm bird taxa from which samples were collected, which can be found at DOI: 10.23719/1532394
