Megjegyzések:	We investigated intersexual morphological differences in tree sparrows (Passer montanus), a species being considered as sexually monomorphic. Molecular sexing of the birds was performed by PCR amplification of the sex chromosome-linked CHD1 gene introns. All measured traits (body weight, wing, tail and tarsus length, bill size and the size of the black throat patch, i.e. badge hereafter) were greater in males than in females and the sex of about 90% of the individuals was correctly categorized by means of a discriminant analysis based on the morphological measurements. Nevertheless, wing length alone was equally good predictor of the sex. Other measured traits had only moderate discriminant value. Our results do not support that tree sparrows can be sexed based on the size of their badge alone. However, some of our results suggest intersexual differences in the function of the badge.
