Phylogenetic relationships of the ovenbird-woodcreeper clade. The 50% majority rule consensus tree obtained from the analyses of the combined dataset (cytochrome b, myoglobin intron 2, ornithine decarboxylase introns 6 and 7, glyceraldehyde-3-phosphate dehydrogenase intron 11, and β-fibrinogen intron 5). Posterior probability values are indicated below the nodes, posterior probability values of 1.00 are indicated with an asterisk. Dashed lines are used to tentatively place taxa (from which nuclear data is lacking) based on their relative position in the cytochrome b tree. Differently coloured branches illustrate where the different lineages were placed in traditional classifications (purple = Dendrocolaptidae, green = Philydorinae, red = Furnariinae, yellow = Synallaxinae). The morphological adaptive radiations and examples of convergent evolution within the ovenbird-woodcreeper family are illustrated by drawings to the left of the tree; the phylogenetic positions of the birds are indicated by numbers in bold font. The left column of birds illustrates large scansorial groups (from above; Pseudoseisura, Berlepschia, Syndactyla, Pygarrhichas, and Xiphorhynchus), the center column depicts groups with terrestrial feeding (from above; Asthenes dorbignyi, Coryphistera, Upucerthia, Furnarius, Tarphonomus, Ochetorhynchus, and Geositta), and the right column portrays small acrobatic birds feeding in the vegetation (from above: Cranioleuca, Xenerpestes, Synallaxis, Schizoeaca, Phacellodomus, Leptasthenura, Aphrastura, Phleocryptes, Premnornis, Margarornis, Heliobletus, Xenops milleri, and Xenops).
