TABLE 4 a in Morphological assessment of the Common Barn Owl Tyto alba (Strigiformes: Tytonidae) supports three species

TABLE 4a. Females. Measured data comparing the morphometrics of three barn owl species units: Tyto alba, T. furcata, and T. javanica. Note the total sample size of each group changes depending on the morphometric because not every owl had complete morphometric measurements. Significant results are highlighted in grey. Adjusted p-values used Holm correction.
