Morphological traits taken for males and females of C. curvipennis lineages. Boxplots show the 10^th, 25^th, 50^th (median), 75^th, and 90^th percentiles. Values above the 90^th and below the 10^th percentile are plotted as open circles. Illustrations correspond to C. c. curvipennis (A), C. c. excellens (B) and C. c. pampa (C) taken from the Handbook of the Birds of the World [32].
