Phylogenetic and geographic relationships of white-eyes. Tree produced by rate-smoothing the ML phylogeny, calibrated with an age of 560,000 years before present at node 1 based on estimates of island age within the New Georgia Group of the Solomon Archipelago. Thickened branches indicate posterior probability ≥0.95 and bootstrap proportion ≥70; 2 inferred insertion/deletion events are labeled near the base of the tree. Bold species names indicate members of Z. [griseotinctus] species complex, all of which inhabit the New Georgia Island Group in the Solomon Archipelago except Z. rennellianus, which is endemic to Rennell Island, and the nominate Z. griseotinctus, which inhabits the Louisiade Islands off eastern New Guinea. Colors on map indicate distribution of Yuhina (purple), Clade A (green), and Clade B (orange). Lineage through time plots track the number of extant lineages (ln) for the entire ingroup and within Clade B alone. The time scale at the bottom applies to the LTT plot as well as the phylogeny. The Quaternary (Q) includes the Pleistocene and Holocene epochs. Bird images illustrate general patterns of diversity within the major clades.
