Table 2.

Estimated ages of the main Arctic Warbler clades

Clades	All samples	Major clades
A--B	1.9 [1.3--2.6]	2.3 [1.5--3.0]
A/B--C	2.5 [1.8--3.3]	3.0 [2.1--3.8]

Estimated by Bayesian inference using the GTR + Γ model and a fixed clock rate of 0.0105 per lineage/million years, and a coalescent expansion growth model (All samples) or birth-death model (Major clades). Values in square brackets are 95% highest posterior density intervals.
