A Dated Bayesian maximum clade credibility tree showing phylogenetic relationships among members of Atlapetes albinucha species. Node bars depict 95% HDP interval, scale bar represents millions of years. Nodal values above branches indicate posterior probabilities/ bootstrap supports of BI/ML. Capital letters depict haplotypes. An asterisk (*) indicate birds representing yellow morphs B Median-joining haplotype network for the concatenated dataset. Each color depicts the geographic provenance of samples: green-northern Chiapas (subspecies albinucha), red-southern Chiapas (subspecies griseipectus), blue-El Salvador (subspecies griseipectus), yellow-Honduras (subspecies fuscipygius) and light blue-Colombia (subspecies gutturalis). Each branch represents a single nucleotide change, transversal black lines along branches depict the occurrence of three mutations. Gray dots indicate median vectors inferred for the data.
