  1. Posterior probabilities (PP) given for each node; estimates are given as mean ages (in millions of years) with 95% Highest Posterior Density (HPD) intervals in parentheses. The divergence time (mean 12.0 MYA, SD ± 1, range of 13.9–10.3 MYA) between mountain gems and bee hummingbirds [25] was used for temporal calibration of the root node of the tree and the mean substitution rates proposed by Lerner et al. [54] to model the tree prior. Node letters correspond to those in Figs 2– 3. NA North America, SA South America, CA Central America
