FIGURE 1.

Consensus Bayesian phylogenetic tree of resident haemosporidian lineages (in bold) and 13 additional Leucocytozoon morphospecies lineages for context. Species names are provided in italics where known. Posterior probabilities shown on branches. Novel lineages are indicated with asterisks. Host preference is indicated for lineages, species, and groupings which had significant z values, (BT) for blue tits or (GT) for great tits. Color coding highlights the three genera: Haemoproteus, Plasmodium, and Leucocytozoon (Groups A–D). Leucocytozoon lineage groups received strong posterior probability scores and showed considerable within‐group sequence similarity. Double dash = 0.18 substitutions
