Table 1. Dating, biogeographic inference and nesting biology. Results from divergence date estimations with mcmctree, summarized as median ages and their 95% HPD for all nodes. Nodes marked with * were calibrated for dating analyses. Ancestral ranges and ancestral nesting preferences are further given for each node; for nesting preference, states with the highest probability are given in bold; for ancestral ranges, only the most probable range and its relative probability is listed for each node. Node numbers refer to Figure 2. Geographic ranges are C = Caribbean, E = Eastern US, ne Mexico, W = Western US, nw Mexico, M = southern Mexico to Honduras, EW = combined distribution of E and W, EC = combined distribution of E and C, EM = combined distribution of E and M
