P-values from the MANOVA on the effect of location on body size-corrected, scaled morphological characters of all species and P-values from Tukey’s HSD tests on differences between locations for the seven Neotropical avian species studied. Response variables and P-values that are statistically significant at α = 0.05 are in bold.
