Of the 75 nodes on the tree, 62 received posterior probability values Ͼ 95%, and 53 of 75 received posterior probability values of 100. Morphology, Kinematics, and Aerodynamic Power. Morphological measurements were made for 484 captured individual hummingbirds from 43 species. Of the 43 species, 42 were included in the phylo- genetic estimate, which contained no polytomies (Fig.įlight trials were conducted on most of these individuals, but accurate kinematic data during maximal load lifts were available for only 347 individuals, but with all taxa represented. Thus, 41 ( n Ϫ 1) phylogenetically independent contrasts were available for comparative analyses.
