Reconstructing the phylogeny of “Buarremon” brush-finches and near relatives (Aves, Emberizidae) from individual gene trees

► Conventional phylogenetic analyses of sequences of several nuclear and one mitochondrial locus recover different gene trees in Buarremon brush-finches and near relatives. ► Three methods for species tree inference based on multilocus data support monophyly of Buarremon as traditionally defined, in contrast to a previously published mtDNA data set. ► Different species-tree analyses recover different topologies and results of these methods appear sensitive to sampling, indicating the difficulty in resolving relationships in the group.
