Chronogram with divergence times estimates of the birds-of-paradise. The divergence times and confidence intervals (grey bars) were estimated under a relaxed clock model implemented in Beast 1.4.7 [33]. For the calibration of the chronogram the postulated separation of Acanthisitta from all other passerines in the phylogeny was used.
