PCoA plots show the microbiome composition based on Bray–Curtis distance matrixes of magpies and great spotted cuckoos from monospecific (M) or heterospecific (H) nests using (A) the whole set of ASVs and (B) only potentially pathogenic ASVs. Ellipses are 95% confidence interval. (C) Box plots showing group dispersions with Bray–Curtis distance matrix (betadisper analyses) of magpies from monospecific (M) or heterospecific (H) nests. (D) Differential abundance of genera from the whole dataset of ASVs differing significantly among species (magpies or great spotted cuckoos) and/or social environments (nestlings from monospecific (M) or heterospecific (H) nests). The list indicates bacterial genera derived from Random Forest analyses with alpha = 0.01. Underlined in red are the potentially pathogenic genera
