The molecular phylogenetic relationships of Haematopus ostralegus within the order Charadriiformes based on sequence of 13 PCGs and 2 ribosomal RNAs (12S rRNA and 16S rRNA) by using partitioned Bayesian analysis. The GenBank accession numbers for each species are shown in parentheses. Values on the branches represent bootstrap values/Bayesian posterior probabilities. “*” represented the nodes received the values of 1.00/100 unless otherwise labeled. The species which was sequenced in this study was underlined.
