The marginal posterior probability density distributions of migration rates ( m ). All parameter estimates are scaled to the mutation rate. The black line represents migration rate from Aegithalos fuliginosus to A. bonvaloti. The grey line represents migration rate from A. bonvaloti to A. fuliginosus. “all” and “allopatric” mean IM analyses based on all individuals and allopatric individuals, respectively.
