FIGURE 4. Morphological comparisons among four Turdus thrushes found in eastern Colombia. Note the smaller size overall of T. l. upichiarum with respect to cisandean T. l. albiventer. Turdus i. debilis and T. arthuri show similar morphology, except for the longer tail and tarsi of the latter. Medial line denotes the median, and 2nd and 3rd quartiles delimit the box.
