Photographs of 15 randomly chosen sparrows were measured again several months later; repeatability between measures was highly significant for all four ornament variables (all R i >0.81, all F >10.17, all P <0.0001).

However, after Bonferroni correction (α-level = 0.0125) the effect on wing-bar brightness would turn to marginally significant ( P = 0.016).
