Figure 12 in Eigensurface analysis, ecology, and modelling of morphological adaptation in the falconiform humerus (Falconiformes: Aves)

Figure 12. Ordination of the falconiform species for which migratory behaviour information was available (32 species) within the space of the first two canonical variates axes of ten eigensurface shape variables. Based on this result 90.6% of training set species were assigned to migratory behaviour groups correctly on the basis of proximity to the group means. Rows of shape models below the ordination plot represent along-axis coordinates through the canonical variates space for CV-1, calculated using the method of MacLeod (2007). In high-scoring taxa the external tuberosity (ET) is more prominent and other protrusions may be noted around the humeral head (H), while in lower scoring taxa the humeral head has a smoother, more rounded appearance. See text for further discussion. Note the CV-2 axis contains no information with regard to group discrimination and should not be interpreted. Species abbreviations are listed in Appendix 1.
