We have examined the saturation of anomalous Ward identities by the low-lying pseudoscalars {pi}{sup 0}, {eta}, and {eta}{prime} to determine the sizes of {eta}{prime}-{eta}, {pi}{sup 0}-{eta}, and {pi}{sup 0}-{eta}{prime} mixing angles. The {eta}{prime}-{eta} mixing angle turns out to be about {minus}20{degree} which is consistent with the recent findings. Our estimate for the {pi}{sup 0}-{eta} mixing angle shows that it could be bigger than the older value obtained from the {rho}-{omega} mixing, baryon mass splittings, and kaon mass difference.
