Relationship between the beak and braincase. Phylomorphospaces of the beak (A) and braincase (B) individually, colored to indicate family (two Accipitrid subfamilies of Old World vulture are also highlighted). Morphospaces of the beak (C) and braincase (D) individually, colored to indicate dietary preference. Partial least squares analyses showing covariation between the beak and braincase blocks in the original shape data (E), the nonallometric shape data (F), and the phylogenetic independent contrasts (G).
