Fig. 2.—

Beast chronogram of 102 passerine species derived from complete mitochondrial genomes. The 14 New Zealand native species are in bold. Branch thickness indicates ML bootstrap support, and the timescale is in millions of years. The insert ML tree shows relative branch length, and a full size version is shown in supplementary figure S2, Supplementary Material online. Colors are the same as in figure 1 for reference. ¹Pseudopodoces humilis is likely Phoenicurus ochruros, see Results section and supplementary figure S1, Supplementary Material online.
