Phylogenetic and haplotype network analysis of COI data for C. carduelis, C. caniceps and the origin of study material A neighbor-joining tree, values on the branches shows bootstrap values and, an asterisk indicates Iranian COI sequences from GenBank B distribution range and collection sites for the samples included in the study. Distribution map of C. carduelis and C. caniceps, with green indicating areas where the species is native resident according to bird species distribution maps of the world (https://datazone.birdlife.org); sampling sites are indicated by red triangles C haplotype network, where colors indicate the origin of the haplotypes (orange: western species; green: eastern species) and the number of bars at each branch indicates the number of mutations.
