FIGURE 5. Principal Components Analysis of the morphological measurements (Tables S1, S2, S3) of the four Turdus thrushes of the present study. red = T. leucomelas albiventer; green = T. l. upichiarum; blue = T. arthuri; purple = T. ignobilis debilis. Note the virtually complete separation between T. l. albiventer and T. i. debilis; T. l. upichiarum overlaps most with T. l. albiventer, less with T. arthuri and still less with T. i. debilis; T. arthuri shows considerable overlap with T. i. debilis.
