Multilocus data from the different genomes are essential to understand the phylogeographic history of species, particularly when a species has the male-biased dispersal pattern. Although Black-throated tits (Aegithalos concinnus) are socially monogamous and cooperatively breeding birds, limited observational data suggested that males may have the ability of long-distance dispersal. We have previously detected three highly supported mitochondrial populations within two subspecies of Black-throated tits (A. c. concinnus and A. c. talifuensis). Here, we used several genetic markers with different inheritance patterns to gain insights about their phylogeographic history. Phylogenetic and individual-based Bayesian analysis showed weak geographical structure amongst nuclear sequences (autosomal and Z-chromosomal loci). Coalescent analysis revealed high levels of gene flow among mitochondrial populations, even between allopatric populations. These results strongly suggested that male-biased gene flow was responsible for the discordant cytonuclear phylogeographic patterns. Consistent with expectation on the genetic consequence of long-distance male dispersal, mantel tests revealed a significant pattern of isolation by distance for mitochondrial sequences, but failed to provide a similar pattern for nuclear genes within a continuous population; female Black-throated tits showed a stronger but not significantly different relationship of isolation by distance than males when using mitochondrial DNA alone. We discussed the contribution of male juveniles with delayed dispersal to the non-significantly different IBD patterns between sexes. Our results using multilocus genetic data revealed aspects of the complex evolutionary history of Black-throated tits and the important role of long-distance male dispersal in the population structuring.
