Fig. 2From: Evolution of body morphology and beak shape revealed by a morphometric analysis of 14 Paridae speciesScatters of the principal component analysis of the morphology of the 14 species examined. a: Scatters of the PC values for body morphology. b: Scatters of the PC values for beak shape. Phylogeny is projected onto the PC values in each plot. c: Phylogeny of the Paridae, including the 14 species examined in this study. The species illustrations refer to HBW alive: http://www.hbw.com/ Back to article page
