Beyond a morphological paradox: Complicated phylogenetic relationships of the parrotbills (Paradoxornithidae, Aves)

► Most comprehensive phylogenetic frameworks of parrotbills in terms of taxa and gene sampling. ► Incongruent mitochondrial and nuclear phylogenies caution against single marker-based phylogenetic inferences. ► Phylogenies help evaluate taxonomic hypotheses and outline numerous topics for further evolutionary studies.
