Interaction matrices of birds and malaria parasites in the two study sites. Also provided are sample sizes (N), the number of associates (degree), species-level specialization (d’), and phylogenetic species-level specialization (wMPD). We placed “TI” in front of each lineage number from Tiputini to distinguish these from “OZ” lineages and an “H” or a “P” in front of each lineage name to distinguish between Haemoproteus and Plasmodium. An “L” is placed after lineage names consisting of more than one haplotype
